EXECUTIVE SUMMARY

Background

According to Japanese governmentsources1, as much as 450 million tonnes (t)of waste is generated every year, of which50 million t is municipal solid waste(MSW), and the number of final disposalsites is rapidly dwindling. A commonlyquoted figure from various sources is thatgeneral waste landfill sites will be fullwithin 10 years and that industrial landfillwill be full by 2007/8.

There is also a recognised problem ofincreasing environmental damage beingcaused through waste disposal such asincreasing global warming, decreasing airquality and long-term environmental effectsof hazardous substances.

In addition forecasted resource constraintsare beginning to impact on manufacturingcosts in Japan, not least due to the closeproximity of materials-hungry neighbourssuch as China and Korea.

Consequently the Japanese governmentinstigated a formal programme of sustainabledevelopment based on the 3Rs (reduce,reuse, recycle) in the 1990s2 and a frameworkof recycling laws was established during2000 to 2003, ranging from packaging, homeappliances, food, construction and end-of-life(EoL) vehicles.

The mission

The substance of this report is based on theeffect and application of the Japanese Home

Appliance Recycling Law (HARL, 2001) with44 million domestic households disposing of18 million appliances each year.

The mission team were representatives ofthe Mini-Waste Faraday Partnership, which isone of 24 Faraday Partnerships funded by UK government and the research councils. The Partnership is developing improvedcontacts between industry and academiawithin the UK in the field of resourceproductivity and waste minimisation in thefive key sectors of food, construction, miningand minerals, metals and electronics.

The team represented a cross-section of theindustry both in size (large UK nationals andsmall to medium enterprises – SMEs) andsectors (waste collection and logistics,eco-design, plastics recovery, WEEE andmobile phone recycling).

Six of the mission team are part of a smallcore team forming a network of industrialmembers set up, under the auspices of theDTI Global Watch Service and the newResources Efficiency Knowledge TransferNetwork, to promote post-consumer plasticrecovery and reuse. A secondary objective ofthe mission was to consolidate the strategyand objectives of this group.

The UK delegation visited leading Japanesecompanies (Mitsubishi Electric – Hyper Cycle,Toshiba, Hitachi, Panasonic – METEC, Sharp –Kansai Recycling, Sony – Green Cycle andTokyo Eco Recycle) as well as meetinggovernment officials at the Ministry ofEconomy, Trade and Industry (METI).

Several mission participants also had ahalf-day visit to the International Plastic Fair2005 at Makuhari Messe. The missionmembers delivered a seminar on Applicationof the WEEE directive in the UK and Europeat the British Embassy in Tokyo to anaudience of over 80 delegates.

Many of the companies visited are marketleaders in the electronics sector and haveadvanced manufacturing/de-manufacturingprocesses. For example, Sharp has inproduction one of the first electronic devicesfeaturing active disassembly using smartmaterials (ADSM) for shape-memory polymercomponents. The main thrust of the missionwas to visit as many recycling facilities aspossible to look at technology and understandany major differences in philosophy.

As previously mentioned the main driver forrecycling is legislative as enshrined in

HARL. This law was formulated in the late‘90s and had a wide consultative processwithin the industry. Hence when the lawwas finally enacted in 2001 most of themajor manufacturers had already instigatedthe policy within their organisations, and inat least one instance visited by the missionhad started to build recycling facilities,although these would be better describedas disassembly factories.

The major original equipmentmanufacturers (OEMs) split into two groups– imaginatively called Group A and Group B– to build recycling capabilities. Group Aconsists of Panasonic, Toshiba andMatsushita; Group B of Sony, Sharp, Sanyo,Hitachi, Mitsubishi and Fujitsu. Thesegroups set up joint ventures (JVs) witheach other, with one partner beingresponsible for – and running – the facilityas the major shareholder and the other

partners being involved as lessershareholders. They also invite the minorproducers to join their consortia dependingon the location of the particular facility.

Regulation and control

Overall responsibility for legislation in theWEEE arena lies with METI. Broadlyspeaking, Japanese society and its legislatureare very ‘environmentally friendly’. Theycommissioned a study and then enacted a‘Basic law for a Recycling-Based Society’(June 2000) which acted as an umbrella for anumber of related laws.

Exhibit S.1 details their relationship but theones most relevant to the mission were theLaw for Promotion of Effective Utilisation ofResources (LPEUR) and HARL, both enactedin 2001. Of these, LPEUR is the more broadlybased and similar to what the EU proposesfor the WEEE directive. However, HARL is themost concise and universally applied as itcurrently covers Japan’s four major homeappliances: air conditioning units, fridges,washing machines and televisions (TVs) –defined as cathode ray tubes (CRTs), notliquid crystal displays (LCDs) which were onlyjust coming onto the market at that time.

The cost of financing HARL is borne by theconsumer, directly and transparently, througha system of unified, government-set charges(Exhibit S.2).

In the case of replacement equipment theshop is required to take back the replacedappliance. The retailer will arrange for the

appliance to be collected and delivered to alocal central stockyard (190 of them aroundthe country) and from here they areseparated by type of appliance and make,then sent to the local Group A or Group Brecycling centre depending on the make.

The key strength of the system is that therecycling centres get a very clean segregatedwaste stream and have very detailedinformation regarding the appliancecomposition and manufacturing methodbecause they have the assembly blueprintsfrom the original build (in many cases theycan scan in the model ID or serial number tohave a precise design specification). There willbe a major difficulty in applying a similarsystem in the UK where this kind ofinformation may not be available.

In the case of redundant or scrappedappliances the system is similar except in a fewminor details. If consumers have details ofwhere the appliance was originally purchasedthey can require the store to take the applianceback. If the store is not known, no longertrading or too far away, they can contact adedicated collection unit to come and pick theitem up. For example, in the case of TVs thisservice is provided by the Post Office.

As mentioned, the system is financed byconsumers, who buy a multipart docket ormanifest from the Post Office. The consumerkeeps the top copy and sticks the remainingdocket package on the appliance; when it iscollected another copy is filed; at thestockyard another copy is removed; likewiseat the recycling centre; and finally the lastcopy is sent to a central data collectionauthority. At any point in the proceeding anyof the participants can check where theappliance is. This proves to be a very conciseand simple audit trail and there is evidencethat consumers do check with the datarecording body that their particular appliancehas been disposed of responsibly. A flowsheet is shown in Exhibit S.3.

Surprisingly, METI – which has overallresponsibility – insists that fly-tipping to avoid paying the disposal charge is virtuallyunheard of.

Within the legislation the government has setstrict targets for the amount of materialrecovered for each group of appliances(Exhibit S.4) and all recycling centres have toreport their figures regularly.

These targets have a tight definition of whatcounts as ‘recovered’, with the fraction of anyappliance being ‘reused’ (due torefurbishment, social reuse, sold on to thirdparties) as being disallowed. ‘Recycling’ isdefined as the total weight of waste sold forrecycling or reuse divided by the total input.

The targets were set following consultationwith industry, obviously based on industryknowledge of the average material weightsof components in each type of appliance(Exhibit S.5).

There is no requirement for the recyclingcentre to achieve better figures but allroutinely do, prompting speculation that thegovernment may increase the targets in thefuture in light of significant year-on-yearimprovements from the recycling centres.When METI was directly asked if this waslikely, it replied that it was very pleased withthe results and, as self regulation was clearlystill delivering improvements, it didn’t wantto punish recyclers by imposing strictertargets in the near future. Again this could beseen as a crucial difference between Japanand the UK.

Due to having a well-defined collectionsystem and only looking at four groups ofappliances, segregation and cleanliness ofoperation was impressive. A standard stillagecage appears to be used to deliver appliancesto site and obviously makes transportationand storage ‘modular’ and compact. Cruciallyit delivers appliances to recycling centres in

‘good condition’ (for example the mission sawvery few examples of TVs with brokenscreens or fridges with the gas pipeworkbroken or leaking).

Industrial investment

The regulations were broadly created inconsultation with industry and widelydisseminated with a guaranteedimplementation date. Consequently the majorplayers such as the large electronicmanufacturers had plenty of time to putmeasures in place. Indeed some facilitieswere already constructed and in operationbefore the laws were enacted. The system ofpayment by the consumer guaranteed arevenue stream for the recycling centres.Finally, by close cooperation the majorsuppliers set up JV companies therebylimiting their exposure to financial risk andreducing their capital expenditure.

Vertical integration with the parentorganisation also made recycling easier – ie cheaper and quicker – and gave a readymarket for recovered materials. For example,virtually all the plastic recycled at KansaiRecycling Systems Corp (KRSC) is reused bySharp – some 150 tonnes per year (t/y) fromHARL appliances, 15 t/y from photocopiersand 10 t/y from personal computers (PCs).

This closed-loop system is seen as a ‘virtuouscycle’ by Japanese companies and featuresprominently in their annual ‘corporateresponsibility reports’ of which they are alljustifiably proud. That said, the industry hasstill invested heavily in the 46 or so recyclingcentres throughout the country, as can beseen by the capital investment numbersmentioned in individual visit reports later inthis document.

Essentially, the Group A and Group Bconsortia operate similarly designed plantsusing similar basic technologies. Theappliances are treated on dedicated lines with

Page 10: Elektricni i elektronski otpad

8

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

combined treatment only happening on theresidual elements at the end of lines orwhere similar components had clearly beenidentified, such as common plastic casings orprinted circuit boards (PCBs).

The amount of manual handling anddisassembly was surprisingly high butobviously very efficient. Some typicalexamples quoted were nine minutes for a TV,12 minutes for a fridge and 24 minutes for anair conditioner.

The use of sophisticated data logging systems(for what are essentially waste handling sites)was in evidence with many able to providereal-time information such as units per hourand weight of each material recovered.

The residual technologies to separate thevarious materials were generally tried andtrusted – such as shredding, magnetic andeddy-current separation, plastic air anddensity flotation – but were applied to veryclean, concentrated feedstock, hencedelivered impressive separation results. There was evidence of some innovativetechnology in the area of plastic separationbut this is available and understood in Europe.

Disassembly was mainly manual asmentioned with the only ‘robot’ technologyseen being a hot-wire separator to dividefunnel glass from tube glass on some of theTV lines. Obviously mechanically assistedmanual handling was common with thefavoured equipment being ‘intelligent’ sensor-controlled motorised conveyors and vacuumlift devices.

Gas recovery equipment from fridges and airconditioners was the common vacuumextraction system but rigorously applied usingloss-in-weight detection to make the processsemiautomatic. The companies were at greatpains to point out this technology at eachfacility as they are clearly very sensitive toany climate change gas issue (this is possibly

part of the Japanese culture – an island nationbeing significantly at risk from sea-levelchange, and the Kyoto Protocol being anational emblem).

Conversely, incineration of any finallyunrecoverable waste stream was generallyseen as acceptable and ‘good practice’.Energy-from-waste (EfW) plants were cited asa good means of disposing of unrecoverablemixed plastics, and mixed plastic/metalfractions ‘recycled’ to non-ferrous smelterswas generally acceptable.

Due to the almost non-existence of CRTmanufacture in Japan – now that LCD TVs arethe dominant equipment manufactured –disposal of leaded glass from TVs is starting toprove difficult, with most being considered forexport to China and some starting to be usedas a silica slagging agent in lead smelters orother pyrometallurgical processes.

One of the advantages of only treatingappliances of known composition was thatmany fractions were being recycled directlyback to the parent companies for 100% reuse,giving a completely closed-loop recycling routefor certain constituents like plastics. Also theuse of JV companies with no intellectualproperty right (IPR) concerns allowed ‘designfor disassembly’ to be explored. Already thenumber of separate parts in appliances wasfalling allowing easier recycling. Somecompanies were putting brand-new appliancesthrough the recycling centres to determinehow they could be ‘designed for disassembly’,using time-and-motion type studies todetermine choke points in the process. As yetthere was little evidence of ‘activedisassembly’ components being used toreduce the manual dismantling operation butclearly some companies such as Sharp haddevelopment programmes in place.

None of the processes observed to recycleappliances was ‘revolutionary’ (bearing in mindwe were only seeing a snapshot of

well-established showcase sites) and couldeasily be applied in the UK. The key differenceis that there is very close vertical integrationbetween the legislators, consumers,manufacturers, recyclers and the supply chainand logistics. With only a few appliances beinglegislated for in Japan this is clearly easierthan the European WEEE directive philosophy.

Conclusions

Japanese companies and stakeholderscovered by and involved in implementingHARL are developing advanced knowledgeof how to run ‘recycling systems’ – thelegal system, infrastructure, plants andlogistics: the HARL system has beenrunning since 2001 and many of therecycling plants since 1999. This has beendone through a strategic approach thatinvolved government (METI), investors andindustry. This knowledge and the learningcurves developed on how to run ‘recyclingsystems’ will enable the Japanese to:

• Set up plants in other countries for their own companies and/or sell turnkey solutions

• Establish ‘recycling systems’ for otherelectronic products based on the learningfrom HARL

• Develop international standards based onJapanese experience

Most of the focus of the missionpresentations was on responses to HARL butit is clear that LPEUR has an important role instimulating recycling and eco-design in otherelectrical and electronics product categories,eg computers, mobile phones, small electricalitems and photocopiers. In addition it wasreinforced that eco-design – and particularly‘design for disassembly’ – is beingimplemented by a number of the companiesvisited (see also the eco-design report3).

The mission team found many examples of‘best practice’, some of which – but not all(due to cultural and economic differences) –are applicable to the UK. These are briefly setout below.

Centre of excellence

• Complete a study of the ‘state of the art’in electronics recycling in the UK to mapagainst emerging opportunities

• Develop some form of strategiccooperation between UK and Japanfocused on the transfer of recycling andeco-design knowledge and technologies

• Develop a UK network of electronicsrecycling technology companies

• Consider the educational element of anysuch centre of excellence as a forum forteaching future generations

Investing in industry

• Develop a UK demonstration recyclingplant based on Japanese knowledge andexperience

• Develop an Anglo-Japanese researchproject to classify the recycling plantsseeking to explore inward investmentfrom Japan

Legislation

• Consider carefully the differencebetween LPEUR and HARL oncompanies as a model forimplementation of the WEEE directive

KEY FINDINGS AND RECOMMENDATIONS

Page 13: Elektricni i elektronski otpad

11

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

• The government should consider settingup a national WEEE recycling R&D facilityor ‘centre of excellence’ (similar toMETEC) to encourage innovative R&D.

• DTI funding should be strategically focusedand, in this arena, made available to ‘kickstart’ integrated demonstrator facilities.National demonstrator funding is vital and,where appropriate, covering 100% offeasibility costs would be key to this sector.

• The current policy of longer-term fundingprogrammes should be encouraged andstructured to persist over a decade ifrequired. The current governmentTechnology Programme ‘Towards ZeroEmissions’ call should be extended toemphasise this area.

• Government support should not stop withR&D but should continue down throughproduct development and field trials tomarket, with a suitable emphasis on ‘newproduct’ manufacturing development. Againthe ‘Sustainable Products’ call in theTechnology Programme is to be encouraged.

• DTI should bring in simple regulations inthe key sectors as soon as possible, witha longer-term view to amending andextending these measures as experienceis gained. An agreed and publishedschedule of reviews would be helpful forfuture industry planning. This would bringstability to the ‘recycling’ market andencourage longer-term investment.

• The government should be encouraged to‘brand’ recycling technologies as a meansof reducing energy consumption, towardsmeeting Kyoto global warming targets.They should also be seen as a method ofsecuring a long-term supply based onrecovered materials.

• Education is seen as a key area both toenlighten the younger generation aboutfundamental recycling and the oldergeneration towards the use of recoveredmaterials as sustainable products. Thisshould be funded and based in a centre ofexcellence similar to Japan.

1 INTRODUCTION

Japan has a population of 127 million living ona landmass of 378,000 km2 whereas the UKhas a population of 60 million on a landmassof 295,000 km2. Population density in Japanis further exacerbated by available land beingmainly concentrated in coastal areas.

Gross domestic product (GDP) is £2,844 billionwith a growth of 1.1% giving a per capitawealth of £22,500 (equivalent figures for theUK are £935 billion, 1.9% and £15,500respectively). Unemployment is 4.4% and theaverage wage is £42,000 for men and £20,000for women. With comparison figures in the UKof 4.7% and £24,000 it can be seen that withnear zero interest rates in Japan the disposableincome is higher than in the UK.

In terms of carbon dioxide (CO2) emissionsJapan is ranked fourth in the world, onlysurpassed by the USA, China and Russia.However, being a nation particularlyvulnerable to sea level change and having theKyoto Protocol to their name, the Japanesehave a heightened awareness of theimplications of inaction. Many times duringmission visits the subject of doing things toreduce global warming came up, not only inthe context of the driver for material reuse toreduce emissions but also in alteringmanufacturing facility management (egMatsushita Eco Technology Centre – METEC– had a policy of reduced air conditioning inits office environment as well as its de-manufacturing facility).

Japan has the world's second largesteconomy; however, the massive growth seenduring the 1980s peaked in the early 1990sand has been replaced by periods of

recession interspersed with slow growth.Recently there has been evidence of another growth spurt but it is still seen as very fragile,and with Japanese exposure to globalmarkets the recovery is patchy (eg during ourvisit Sony announced worldwide jobreductions of 10,000 with analysts predictinglarger cuts to come4).

The Japanese government continues to takesteps to stimulate the economy throughmassive spending programmes, includingheavy investment in R&D. The total scienceand technology (S&T) budget for 2003 is¥3.59 trillion (£19.4 billion), an increase of1.2% on 2002, indicating a continuedcommitment to this sector.

Private sector R&D investment is alsomassive, and increasing, accounting for 78%of total national spend, including a significantamount on basic research. The top 10Japanese companies invest more in R&Dthan the whole of the UK (public and privatesector). Much of this is invested outsideJapan, with around 160 Japanese companieshaving R&D or design centres in the UK(46% of Japanese investment in the EU), andover 250 Japanese companies manufacturingin the UK.

Paradoxically the large number of SMEs seenin the UK is not so evident in Japan as thisrole in the economy seems to be serviced byfocused divisions within the larger companies.

Recycling is addressed by the majormanufacturers supporting JV enterpriseswhere one of them, dependent on location,holds a controlling share but treats redundantequipment arising from the other partners aswell as its own.

The Japanese economy is heavily dependenton raw material imports, having few naturalresources of its own. Increasingly resource-hungry neighbours such as China are alsohaving a supply and demand effect. Recentincreasing oil and metal commodity priceshave been particularly significant as a driver toassist WEEE recycling. Japan’s electronicssector is a major consumer of plastics, whichare heavily dependent on oil prices.

Meanwhile, contrary to the trend in desktopcomputing where precious metals content isdropping, the component-rich new electronicdevices such as personal digital assistants(PDAs) and mobile telephones are using anincreasing amount.

Another key market is TV technology, withthere being very few CRT manufacturers inJapan now as production moves to plasma andLCD screens. Moves to this new technologyare generating large numbers of CRTs beingrecycled but limiting the closed-loopphilosophy as recovered materials such as leadglass are not being recycled to new CRTs.

High-level aims

The high-level aims are to identify:

• The mechanisms put in place by theJapanese government to achieve itstargets for electronic recycling

• The approach taken by industry to matchthis aspiration

• Integration of academia with industry to transfer R&D expertise into industrial processes

• Multidisciplinary collaboration to bringabout step changes in technology

• Training capabilities and method of implementation for the overall recycling targets

• Integration of novel technologies withtraditional recycling technology both inindustry and academia

• Complementary strengths of the Japaneseand UK manufacturing base to identifypotential new alliances

Japan represents 23% of total EU imports ofelectronic equipment, with a trade deficit of€14 million. The information gathered fromthis mission will be exploited in several ways.

First, comparisons will be made with theapproach adopted within Japan to introducenew technologies, specifically in the field ofplastics and metals recovery, and moregenerally in recycling technologies. Examplesof best practice will be translated to potentialadoption within the UK context to act as theEU clearing house.

Secondly, particular technologies will beinvestigated to identify the strengths withinthe UK and those in Japan to improvecollaboration to develop improved

manufacturing principles. For example theadvantages of active disassembly are not wellunderstood in the UK and the Japaneseperspective would be important.

Finally, actual manufacturing capability willbe assessed to determine if improvedcooperation will result in advantages forboth markets.

Mini-Waste Faraday is already operating toidentify R&D needs for industry alreadyfamiliar with this technology, and henceimprove productivity within those companies.In addition it is assisting companies that havenot already looked at exploiting thistechnology by introducing them to worldexperts in the field. By translating theexperience and expertise in Japan, thisprocess can only be improved and thereforeboth the rate of advance of the technologyand the rate of uptake is likely to increase.

Specific objectives

Following release of the WEEE directive inEurope, Japanese manufacturers are keen tosee recycling sites established in Europe toaddress the producer responsibilities obligation.In Japan there is a national collection systemfor the four major appliances with two industrialconsortia (Group A and Group B) established totreat them. The two groups operate 41 sitesacross the four major islands.

This solution is similar to the NationalClearing House system being considered inthe UK. However, areas of particularweakness were identified within the EUeconomy around the collection andsegregation of these wastes.

2 AIMS AND OBJECTIVES

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Another significant gap is the area of plasticsrecycling and recovery. This technology gap isseen to influence the shredding andsubsequent separation technologies, thesebeing a particular strength in Japan.

The areas of interdisciplinary research havenot previously been investigated, andtherefore no conclusions can be drawn on thecurrent state of development.

Several specific areas are thus of majorinterest to the mission team:

• Best practice for collection and segregationof WEEE

• Perceived needs for improved separationtechniques, including depollutionprocesses

• Advanced shredding and mechanicalseparation

• Performing of novel leaching andelectrochemical reactions to recovermetals

• Improvement of metal revalorisationefficiencies

• Performing of novel processes to recoverplastics

• Level of plastic revalorisation efficiencies (if any)

• Recycling capability (particularly from small-scale collection sites to large processingunits)

• Uptake of technology by the uncontrolledsector of electronic goods, comparing thiswith the ‘big’ four proscribed by HARL

• Tools available to audit the logistics of thecollection system and recovery routes

Introduction

Sustainable waste management has been ahigh priority for the Japanese government forthe last 20 years with their enormousmanufacturing base and limited naturaldisposal options. Existing landfill space is dueto run out in 2008 and the government hasbeen following a planned strategy since theearly ‘90s under the basic 3Rs – reduce,reuse, recycle.

WEEE legislation was clearly the key focus ofthe mission visit but WEEE is just part of acoordinated range of legislation formulated bygovernment in close cooperation withindustry. With an annual 450 million t ofwaste arising from industrial production andconsumption, the country has been seekingto reduce dependency on both naturalresources and end disposal, and seessustainable environmental development as an

essential part of economic progress. This mindset seems to be carried through toJapanese industry which, with its culturalcommitment to R&D, appears to view thechallenge as an opportunity to improvemanufacturing and design processes.

The Japanese government has therefore builtan environmental strategy around the 3Rs –reduction of waste generation, reuse of parts,and recycling of used products as rawmaterials – with the aim of reducingdependence on natural resources andmitigating society’s environmental impact.

This strategy is underpinned by theFundamental Law for Establishing a SoundMaterial-Cycle Society5 that was put into forcein January 2001 and establishes the basicprinciples under which other environmentallegislation should operate. This imposes theobligations of different sectors and the

measures to be taken by national governmentand comes under the responsibilities of METI.Under this come the two key laws that thengovern the application of detailed regulation‘on the ground’. The Waste Management Lawbasically deals with disposal whilst the Lawfor Promotion of Effective Utilisation ofResources (LPEUR) deals with the 3Rsthrough product-related law.

This sequence of waste and recycling law isalso then supported by a Green PurchasingLaw, creating legislative circularity for theproduction process and a complementaryrange of strategic goals.

Additional supporting waste-related legislationhas also been applied such as the SoilContamination Countermeasures Law, the

Page 23: Elektricni i elektronski otpad

Animal Excrement Management Law foragricultural waste and the Law for PromotingManagement of Release of ChemicalSubstances. Thus there is a full range oflegislation applied across both the municipaland industrial/commercial waste streams.

The key driving legislation for the HomeAppliance Recycling Law (HARL) is LPEUR.This was applied in April 2001 and providesfor 3R measures to be taken by business inthe production stage – ProducerResponsibility. This includes design, labellingfor separate collection and the developmentof an end-of-life (EoL) take-back system.

It applies responsibilities to each party in thesupply and consumption trail:

Businesses• Rationalising the use of raw materials with

the aim of minimising • Using recyclable materials and

reusable parts• Promoting their use at EoL

Consumers• Using products for as long as possible• Using products with high recycled content• Cooperating in separate collection

National and local government • Taking financial measures• Promoting green procurement• Promoting S&T development

Ten designated industry areas and 69 productitems were identified to be addressed byLPEUR, covering around 50% of municipaland industrial wastes (Exhibit 4.3).

This all-encompassing law therefore requiresthat even those products not directly coveredby specific producer responsibility are underpressure and scrutiny to be encouragedtowards improved environmentalperformance. It has also led to thedevelopment of additional take-back schemes

for household PCs and portable batteries.

For some years, consumers have had theability to return EoL computers through anational take-back scheme where thecomputer could be packaged, taken to a localPost Office and returned to the manufacturerat consumers’ expense. In October 2003,manufacturers voluntarily started to include arecycling mark on computers entitlingconsumers to return them free of charge atEoL but with an additional recycling feeincorporated in the sale of the product.

For compact rechargeable batteries, a nationalreturns system has been set up atmanufacturers’ cost with collection points inshops and a national recycling centre.

Home Appliance Recycling Law (HARL)

The main purpose of the mission was toinvestigate HARL and the facilities being usedfor the recycling process.

This law is an excellent example of theJapanese approach to environmentalsustainability in applying the following process:

• It appears to have been developed jointly –and in a coordinated and collaborativespirit – by industry and the relevantJapanese ministries

• It set down clear responsibilities, a clear timetable and clear environmental objectives

• It limited application to gain what wasconsidered to be the optimum achievable benefit

• It gave industry a risk-free framework inwhich to invest

HARL was passed in 1998 giving theproducers – manufacturers and importers – of four domestic appliance types theresponsibility of providing a national take-backscheme and achieve recycling targets. Air conditioners, washing machines,

Exhibit 4.3 Key sectors affected by LPEUR

Page 25: Elektricni i elektronski otpad

televisions and fridges/freezers were targetedas the items where the greatestenvironmental net benefit could be achieved.

Japan has ~44 million households disposingof ~18 million of these units each year,equating to ~1 million t. Before HARL,71% of these items were disposed ofthrough untargeted disposal, mostly aswaste, although there would have been asignificant quantity entering the scrap metalindustry. The remainder were exported(24%) or sold as second-hand goods (5%).

Since HARL, it would appear that ~62% areentering the take-back process andachieving an average 72% recycling rate.History does not currently relate whathappened to the 38% that do not enter, but it is assumed that they get resold orexported although there is acceptance that1-2% are ‘illegally’ disposed of which wouldsuggest fly-tipping. If this is the case, thisequates to around 100,000+ units a year, a not inconsiderable problem.

Requirement

The regulations lay down specific recyclingtargets for the four types of appliance andonly relate to household waste equipment.Business WEEE is not covered by HARL,although under LPEUR businesses have aduty to maximise recycling.

The recycling levels are as follows:

• Air conditioners 60%• Televisions 55%• Fridges/freezers 50%• Washing machines 50%

‘Recycling’ is defined as the total weight ofwaste sold for recycling or reuse divided bythe total input.

There are no targets for collection, butitems collected must be recycled throughthe system.

The system had to be in place forcommencement in April 2001, at which pointmanufacturers took responsibility for thecollection and recycling of these items.

The regulations required manufacturers andimporters to set up a national collection andrecycling infrastructure. Manufacturers splitthemselves into two groups which then setabout building the recycling plants on thebasis of shareholdings:

• Group A – 40% of the market withMatsushita (Panasonic) and Toshiba as thetwo largest members: 25 recycling plants

• Group B – 60% of the market with Hitachi,Mitsubishi, Sharp, Sanyo, Sony and Fujitsuas key members: 15 recycling plants

Group A has effectively contracted out theoperation of the plants to waste managementcompanies whilst Group B has built theplants itself.

Plants are built on the basis of prime

manufacturers having the main shareholdingwhilst the other manufacturers and importerstake a small shareholding.

These plants are fed by a national collectionsystem operating through 380 designatedcollection points that act as bulking and transferfacilities. The plants will only take back productbrands related to their Group companies.

Collection is carried out primarily throughelectrical retailers who are required to take backused products from consumers either whenthey purchase a new product or if a consumerdelivers the old product back to where itwas bought from with proof of purchase. On delivery to the retailer, the consumer willpay a national recycling fee plus an additionalamount (£2.50 – £10) put on by the retailer tocover transport costs to the collection point.

The national recycling fees are currently:

• Television (CRT) ¥2,700 yen (~£13.50)• Fridge/freezer ¥4,600 (~£23)• Washing machine ¥2,400 (~£12)• Air conditioning unit ¥3,500 (~£17.50)

A fridge/freezer unit could therefore end upcosting the consumer over £30 on disposal.

A voucher system is used to track all itemsand enable the recycling centre to claim backthe recycling fee from the retailer (explainedlater). These vouchers can also be purchasedfrom the Post Office and consumers can takeproducts direct to the designated collectionpoints although only about 10% do. In thisinstance the recycling plant would claim therecycling fee back from the Post Office (asmunicipalities also can).

The regulations apply strict monitoringrequirements: all recycling plants are requiredto submit monthly returns showing thenumber of units received and the level ofrecycling achieved.

6 PROGRESS AND CURRENT POSITION

The regulations have provided themanufacturers with a clear basis forinvestment, ensuring guaranteed supply andcertainty of revenue. The results havetherefore been extremely encouraging andhave led to long-term development towardsimproving both recycling rates andenvironmental design.

The Group A/B system provides some degreeof individual producer responsibility therebyencouraging improvements in design fordismantlability. Indeed, it was evidentthroughout the mission visit that thecompanies operating the plants saw them asvery much part of their R&D structure, and anumber of manufacturers test their equipmentthrough the plants before it is released.

The level of recycling achieved is impressive,with year-on-year increases for both quantitiesof units collected and appliance recycling rates(Exhibits 6.1 and 6.2), but this is achieved atrelatively high cost compared to expectationsin Europe and especially in the UK.

The main reason for the high costs is theextremely high level of manual disassemblythat is applied; but if consumers are preparedto accept the high costs, there is littleincentive to reduce them. However, it wasindicated that the level of consumerdissatisfaction with the recycling fees hasgrown to such an extent that municipalitiesare complaining of significant increases inillegal disposal – fly-tipping.

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

The government is therefore said to beconsidering a review of the regulations thatwould require manufacturers to apply a visiblefee to the sale of new products. This would belikely to lead to pressure to bring down thecosts of recycling to avoid manufacturersbeing uncompetitive in the market, especiallyagainst imports, and could in turn adverselyaffect recycling rates as recycling plantslooked for savings in their recycling costs.However, it was claimed by some plantoperators that they believed that their currentmethods were as cost effective as could be

achieved because of the relative value ofrecyclables compared to disposal costs if theyweren’t recycled.

It is also interesting to review the technicaldata relating to materials recovered throughthe recycling process for 2004/5 (Exhibit 6.3).

In addition, 995 t of chlorofluorocarbon (CFC)coolants were extracted from air conditioners,plus 311 t of coolant CFC and 625 t ofinsulator CFC from fridges and freezers.

HARL ticketing system

One key element in the successfulimplementation of HARL is the use of aticketing or voucher system that ensures thetraceability of an EoL appliance on its journeyfrom the consumer to the recycler.Introduced about two years ago, the systemhas been found to be a very useful way ofmonitoring and tracking EoL appliances. Thesystem is administered by an organisationknown as the Home Appliance Recycling LawTicket Centre, a public foundation owned bythe Japanese government. (The ticket centreis regulated by HAPA, a trade association ofappliance manufacturers, but it is ultimatelyunder government control.)

The basic process employs five tickets per itemto be recycled and these are used to track theprogress of the appliance through the recyclingsystem. Each ‘ticket’ consists of a book of fivecopies each printed with an individual numberand, in total, costs the equivalent ofapproximately £15, although this amount variesfrom appliance to appliance. The tickets containdetails of the appliance, the name of theretailer and manufacturer and, from theinformation and reference number on theticket, consumers are able to check the statusof their appliance, eg to find out whether it hasbeen returned to the manufacturer or sent onto a third-party recycler. Consumers thus havefull traceability of their appliance via thisrelatively simple system. (They are able to findthe status of an electrical appliance which theysubmitted for recycling by accessing the webpage of the Association for Electric HomeAppliances (AEHA) and using a checkingsystem that tracks the status of all collectedelectric appliances.)

The ticketing scheme places a number ofobligations on people and organisations inorder to ensure that the process worksefficiently. For example, consumers areobliged to both cooperate in appropriatelytransferring used appliances to retailers inorder to ensure recycling and to agree to paythe necessary fees for the transfer andrecycling of those appliances. Similarly,retailers have an obligation to take back usedhome appliances both when the appliancesare those which retailers themselvespreviously sold to consumers and whenretailers sell the same kind of homeappliances to consumers. They also have anobligation to transfer them to the relevantmanufacturers or importers. Manufacturersand importers are then obligated to receiveappliances for recycling at designated take-back sites and to recycle them according tothe recycling standards set by the Japanesegovernment. To date, 46 dismantling factorieshave been established in Japan.

Retailers and manufacturers have anobligation to keep the tickets for three years.The scheme works as follows. One voucheris given to the consumer when an item isdelivered to the shop for recycling. Thisvoucher provides evidence of delivery of theappliance for recycling and payment of theappropriate fee. This fee is determined by theparticular type of equipment to be recycledand also includes an additional amount tocover the cost to the shops of transportingthe item to a take-back site. One copy isretained by the shop and the other threetravel with the item to a designated inputsite. At this point one copy stays at the siteand the final two go with the appliance to therecycling plant. The recycling plant then sendsone voucher back to the shop in order to

7 DATA RECORDING AND REPORTING

Page 31: Elektricni i elektronski otpad

initiate payment of the recycling fee and itretains the final one for its own records. Ifconsumers take items directly to adesignated collection point, they can obtainbooks of tickets from the Post Office. Aschematic of the process is shown in Exhibit7.1 and some actual vouchers in Exhibit 7.2.

Role of the Post Office

The Japanese Post Office is used toadminister the ticketing system because it isboth convenient for the consumer andbecause it is also seen as an independentbody with the required infrastructure to copewith such a large undertaking. It also gainsrevenue from sales of tickets. This relativelysimple approach is in significant contrast tothe UK, where the possibility of establishing aclearing house was originally proposed butwas eventually shelved due to the predicted

high costs. In contrast, the Japanese havemerely utilised an asset which they alreadyhave in place.

Role of the consumer

One of the fundamental reasons why HARLappears to work so well is because theJapanese public seems extremely willing toparticipate in the scheme even though thereis actually a substantial cost incurred. Thishighlights the significant differences in bothnational culture and individual ways ofthinking between the UK and Japan.

It is difficult to conceive of the average Britishconsumer being willing to pay £15 or so tohave old appliances removed and recycled.Even before the new European WEEElegislation comes into force, it is frequentlypossible to find EoL electrical and electronicappliances abandoned at the roadside. Theimposition of a fee such as is used in Japanwould surely cause this type of illegal activityto escalate further. In Japan, although theconsumer is obligated to ensure thatredundant equipment is disposed of in thecorrect manner, there actually appear to becultural reasons that encourage individuals toparticipate in recycling.

It has also been suggested that in the nearfuture consumers may be required to provethat they have recycled their old equipmentwhen buying new equipment. This goes tothe take-back ethos where, if an appliancehas not been returned or if it has beendumped illegally, a penalty would be payable.In this case, by acting correctly, there wouldbe a built-in incentive.

Benefits to manufacturers

The ticketing scheme offers a number ofbenefits to manufacturers. For example, theyget market research information on sales oftheir appliances. They can also trace theirappliances to ensure that they have been

disposed of correctly. This of course is veryimportant to manufacturers as it can enablethem to adjust their supply chain accordingly.It also enables them to monitor theirenvironmental reports. This is somethingwhich is deemed to be very important toJapanese companies as can be seen fromthe annual reports produced by all of themajor large companies.

Benefits to the retailer

Retailers, as with manufacturers, are able toexercise stock control, to gain marketassessments and an insight into new trends.The ticketing system gives retailers fullcompliance with HARL, something whichboth they and the manufacturers have signedagreements to uphold. Participation andsupport for the system can also give acompany the ability to extol its greencredentials.

Benefits to the government

The ticketing system enables the governmentto gain in several ways, as it is able to collectdata on imported electronic goods and also tounderstand how the electronics sector isperforming. It also has control over recyclingand can monitor the efficiency and impact ofits home appliance recycling legislation.

In summary, the Japanese government hasput in place the ticketing system to ensurethat there is a completely transparent audittrail which can be audited at any level andwhich has the agreement and support of allthe manufacturers.

Introduction

On 5 June 1998 Japan published the Law for the Recycling of Specified Kinds of HomeAppliances after consultation with majorstakeholders. The enforcement was tocoincide with that of the Basic Law forEstablishing the Recycling-Based Society on 1 April 2001.

Eighty percent (by weight) of discardedproducts consisted of air conditioners,washing machines, CRT televisions andrefrigeration equipment. These products also

contained substances of concern such asleaded glass and ozone depleting gases.

With the assurance of the Japanesegovernment regarding costing, the majorJapanese manufacturers joined in groups(Group A and Group B – see Exhibits 8.1 and8.2) and began researching the mostefficient methodology for processing theseproduct lines.

An advanced disassembly and sorting systemknown as the ‘HEART System’ (High EfficientApplicable Recycle Technology) was

developed following experimentation withwhole product shredding and manual removalof materials from conveyor lines andcryogenic immersion of products in liquidnitrogen (-120ºC) and crushing technologies.Although some cryogenic process continues,it is considered impractical with desiredthroughputs. Shredding and picking linescontaminate materials with hazardoussubstances, prevent reuse of certaincomponents and it is considered a health andsafety risk to the workforce.

Eventually a basic concept was developedwhich can still be seen today at the majorityof processing plants, combining manualdepollution or pretreatment with shreddingand separation technologies. The systemdeveloped (Exhibit 8.3) considered thepossible future inclusion of other productlines such as office equipment, vendingmachines and gas instruments.

Processing systems

The processing plants visited by the missionteam in 2005 still appeared to follow theoriginal concept (Exhibit 8.4).

The containers are product specific on arrivalso some form of sorting has already takenplace, presumably at the manufacturer’scollection facility, of which each groupmanages 190 facilities. Eighty percent ofproducts are Japanese.

Products also arrive group specific: Group Aplants only process Group A products, aconvenient system that is unique to Japaneseculture, and a benefit unlikely to work outsideJapan. Also each individual product carries thefifth sheet of the HARL manifest including barcode; these are read by bar code readers andthe information contained uploaded to themanagement software system and to theAEHA website where consumers can monitorthe movements of their discarded appliances:www.rkc.aeha.or.jp (only available in Japanese).

Manual depollution or pretreatment

The four product types are sorted into lines,before any manual disassembly; the productis identified by its bar code and weighed.Each product type then follows a prescribeddisassembly procedure.

• Refrigerators

Any single type polymers such as saladcrispers or vegetable drawers are removedand granulated with others of the samepolymer type. Plastic coated steel shelves areremoved along with the magnetic door seals.Refrigeration units are then aligned to aid

refrigerant gas removal, using a mechanicallifting device. The gas is vacuumed into acontainer which is located on a scale system,allowing the monitoring of the refrigerant gasremoved and determining the contents of thecontainer, to allow replacement when full. The compressor is then removed, punctured anddrained of oil. The remaining carcass is thenpositioned ready for shredding.

• CRT televisions

The casings are unscrewed and identified bymaterial type; cabling, speakers, PCBs,copper rich components, steel banding andelectron guns are all removed and separatelycontainerised for further processing. Some ofthe plants visited went on to separate thedifferent glass types using the ‘hot wire’method; at METEC this procedure has beenautomated using an optical system for thepositioning of the hot wire. Others send theremainder to other plants for separation.Sealing with tape or adding water containedthe phosphorus coating on the panel glass.

• Washing machines

The major differences noted betweenJapanese and European washing machineswere that Japanese units were upright twintubs with salt water counterweights whereasEuropean units tend to be front loaders withconcrete counterweights. The usual manualdisassembly of cabling, PCBs and single typematerial was observed; in addition a purpose-built press was used for separating motordrives from PP tubs and extracting salt waterfrom the counterweights.

• Air conditioners

The major task in the processing of airconditioning units is the removal of refrigerantgases – ozone depleting substances such asCFCs, or hydrocarbon greenhouse gases. Theremainder of the unit is becoming more andmore single type material and copper-rich heatexchangers, all of which is separated. Theremaining carcasses of these appliances thengo through a shredding and separation process.

Processing technologies

The five processing plants visited by themission all had noise, odour and dustabatement systems, and all seemed to havesimilar primary shredders – a vertical designcombining shredder and hammer millproperties. All investigations indicated theseprimary shredders all came from one of twomakers: Kubota and Kinki kogyo.

At least one processing plant had requestedmodifications to be made to their Kinki kogyounit and now their parent company holds thepatent for this design.

Only one twin-shaft wheel shredder was seenat METEC for processing refrigeration units.

The next standard processing observed was amagnetic separation device such as a rotatingband magnet for removing ferrous materials. Allprocessing plants claimed between 99.5% and99.8% purity rates for ferrous outputs. Then acombination of eddy current and specificgravity separation units was used to separatealuminium, copper and polymers, with all plantsclaiming between 97% and 99% purity rates.

Refrigeration systems were processedthrough a polyurethane air separator and thefoam was heated to extract the maximumamount of blowing agent from the foammatrix. The foam was processed through alarge diameter outlet briquetter.

Exhibit 8.14 Briquetted polyurethane foam (Japan)

Television glass types were processedthrough a crusher and despatched as cullet.

Some plants were further developing plasticseparation by type, predominantly by specificgravity or flotation, or a combination of both.Polymer separation by type appeared to bethe next important issue to the processingcompanies, if not in-house by otherprocessing plants.

Summary

A great deal can be learnt from the systemsused in Japan, although much of theworkings are dependent on Japanese cultureand would not transplant to the UK orEurope. The many experiences anddevelopments made by such a well-organisedculture and people would transfer into the UKas genuine cost savings in logistics andprocessing and – particularly so – to the valueadded to the material due to manualdisassembly. Markets for these materialsrequire quality and quantity; the ‘Japanesesystem’ seems to increase quality withoutaffecting quantity.

The mission to Japan was to take anoverview of electronics recycling technologiesand report back on any new or developingtechnologies that may be of any interest toUK companies. Of particular interest was theplastics recycling and reuse element.

Despite preconception before the mission,the level of product disassembly found inJapan is similar to that seem in the UK atplaces such as the Hampshire Trust recyclingsite in Portsmouth. The difference is in scaleand efficiency. The majority of disassembly ismanual on a production line basis, lookingmuch like an assembly plant in reverse.Dedicated lines for each major HARL item arestandard, and segregation of the incoming‘product’ by both type and manufacturer isobviously a very significant advantage.

In general the ‘good quality’ of the returnedgoods was apparent, with no evidence of theUK policy of ‘compacting’ WEEE goods intoskips. There was no evidence of post-consumer damage that is common in the UKwaste stream. This is patently a product of themanufacturer ‘take-back’ system previouslymentioned, reinforced by cultural attitudestowards cleanliness, recycling and protectingthe environment. Whether this attitude isextended to post-consumer goods not fallingunder the HARL legislation was difficult togauge as the mission did not see any, otherthan small quantities of PCs being recycled.

The main ‘novel’ investment in the recyclingcentres seemed to be in avoiding manualhandling by the use of air lifts and motorisedconveyors but this was by no meansuniversal and the whole process still involveda very high degree of manual labour.

Unlike the assembly plants for these goodsthere was no evidence of robotic dismantling,the nearest to it being the near universal hot-wire machine to separate funnel and tubeglass of televisions.

Easy-release technology – smartdisassembly

The mission team were also looking atemerging technologies and development ofcurrent and newly implemented technologiessuch as active disassembly (AD). This is amethod of disassembling products into theirseparate components, and is a significantstep towards meeting of WEEE requirementsby manufacturers. Any singular or combineduse of specifically engineered and smartmaterials, adhesives, layers and parts, integralor discrete, plays a key role within AD. Itallows for a cleaner, nondestructive, quickerand more efficient method of componentseparation. The term ADSM (activedisassembly using smart materials) istherefore synonymous with AD. Robotics canalso be used within AD and is referred to as‘automatic disassembly’.

The mission visited all major manufacturers inthe electronics industry such as Panasonic,Sony, Hitachi and Sharp, and asked whetherAD technology was being considered forimplementation within their product range. Allexcept Sharp said that they had no interest inthe technology. Although this may be true italso may be because the topic iscommercially sensitive. Sharp’s development– ‘easy-release technology’ – is beingimplemented in one of its products.

A video was shown of a shape-memory alloywasher being used on a screw fixing for abattery casing. Immersion in boiling watercaused the split c-washer to expand andrelease the screw fixing. This has greatpotential for the rapid dismantling ofappliances using heat instead of manuallabour and shredding machinery. However, itwas apparent that this was not in commonusage and was not seen in the post-consumer goods being recycled. Subsequentintelligence in the UK has indicated that thetechnique is also being used by Sharp insome of its LCD screen manufacturing, butagain probably only in high-value items.

The product they revealed to us that was intrial mass production was a mains charger fora mobile phone; the units were beingproduced in Poland. However, having seenthe presentation they gave to us it is evidentthat they may well be using this technology inLCD flat panels for televisions.

The AD technology used was in the form of‘shape-memory washers’. Shape-memorymaterials can be polymers or metal alloys.Such a material is manufactured to hold a setshape until it is taken to a triggertemperature, at which point it adopts asecond set shape. When the product needsto be disassembled it can usually be heatedor cooled. At this point the snap-fit willautomatically transform to allow release.Trigger temperatures can be set to a fairlyaccurate range of values. However, in theliterature other means of triggering thedisassembly through microwave, infrared,pressure, sound, electric current or magneticfields have also been studied.

Exhibit 9.1 is an example of the shape-memory washer being used by Sharp and anexample of the system that the EoL productwill pass though to be disassembled, thisillustration showing a temperature modelwhich triggers the disassembly process. Itwill be interesting to see how EoL productsthat have this technology built in are dealtwith. The recycling market will have to evolveto deal with this new challenge.

10 MATERIALS RECOVERY AND MARKETS

10.1 Plastics recycling

The majority of plastics recycling informationcame from a presentation by Mr Kamaguchiof Sharp who was extremely knowledgeableand helpful.

Plastics account for 20-40% of the massprocessed but over 50% of the volume. Japanestimates that the disposal volume of electricalwaste will increase 1.4 times by 2010, andlandfill space will be exhausted by 2008.

Quantities of plastics arising from electricaland electronic (E&E) waste appliances inJapan are estimated as:

• HARL appliances 150,000 t/y• Photocopiers 15,000 t/y• PCs >10,000 t/y

Sharp presented a summary of availablerecycling routes for plastics (Exhibit 10.1).

In order to build a sustainable, reuse society,it is necessary to promote self-recyclingmaterials as much as possible – using theclosed material recycling (CMR) route.

Open material recycling often leads to only onereuse cycle before eventual disposal to landfill.

An explanation was given of the many factorsthat could lead to degradation of materialproperties during the lifetime of a plasticcomponent (Exhibit 10.2).

Sharp has developed a way to analyse theantioxidant level in the recovered material,and conjectures that antioxidant is‘consumed’ during the lifetime of a plasticcomponent. When the level drops below athreshold level (~100 ppm) then the materialproperties begin to tail off rapidly asmolecular degradation occurs. It is possible torevitalise the lifetime of polymers by addingmore antioxidant to the resin before re-extruding (Exhibit 10.3).

The inclusion of foreign bodies in the polymermatrix also leads to a reduction in materialstrength due to stress concentration effects (asmeasured by the Izod impact strength test).This problem was being overcome by improvedwashing methods and the use of melt filtrationto minimise the level of foreign parts.

An example was given of the CMR route forthe polypropylene (PP) material fromrecovered washing machine drums. The partto be recycled is first carefully separated fromthe machine and other parts (eg a hydraulichub-puller was used for drive-motor removal).Sharp showed a video clip of the closed-looprecycling process for this material, illustrating:

• Drum disassembly method• Initial cleaning of adhered

dirt/residues/labels• Shredding on site – down to ~10 mm chips• Water washing in vertical rotary friction

washer • Drying with rotary dryer unit• Analysis to determine the degree of

antioxidant in the recyclate chips – as thebasis to evaluate remaining lifetime of thepolymer

• Mixing with antioxidant additive (in tumblemixer)

• Melt filtration in extruder• Pellet forming in water bath system

Finished plastic pellets are reused to makelarge parts for Sharp products (eg condensercover plate for rear of A/C unit, or fridge backcover tray). Product moulding examples shownwere 100% recycled resin. Sharp has utilised420 t of recovered plastic in closed-loopapplications in the four HARL product types in2004. It has set a target of 500 t in 2005(estimated at around 7-10% of plant annualtonnage, if all from the Osaka plant).

Plastic recycling rates

The data collected centrally by METI for theoverall recycling rate in Japan show the levelof plastics found in disposed items incomparison to the target recycling rates foreach HARL product. The estimated fraction ofplastic by mass in the four product streamscompared with the recycling target is shownin Exhibit 10.4.

A set of pie charts by METI analysing thematerial types actually recycled for eachproduct group has very small sectionsdedicated to ‘other valuable materials’(estimated at 2-10% by mass). This materialgrouping is stated to include ‘printed circuitboards and other plastics’.

At several of the sites visited by the mission thecompanies were claiming much higher levels ofactual recycling (eg 80-95%) than the targetfigures. These higher levels can only be claimedif a high proportion of the plastics content isbeing recycled (or recovered).

For example, at Sony’s Green Cycle centrethe quoted recycling rates for 2004 were:

• Air conditioner 91.4%• Television 92.9%• Refrigerator 81.5%• Washing machine 89.5%

Refrigerator 43.4% (inc foam) 50% 63%

Washing machine 34.7% 50% 65%

Page 45: Elektricni i elektronski otpad

At Hitachi’s Tokyo Eco Recycle, Dr Kenji Babaquoted a recycling rate of 98% (although theaverage was stated as 70% elsewhere in thepresentation).

The measurement of the recycling rate mustbe analysed to understand this information. Itis clear that the individual companies areincluding thermal recycling of mixed wasteplastics – and also urethane foam used asrefuse-derived fuel (RDF) – in their in-housefigures. This would not count towardsrecycling in the UK.

The sites visited by the mission were also likelyto be the ‘showcase’ establishments for eachcompany. As the larger firms operate severalrecycling centres, there is likely to be a reducedrecycling rate at the sites where less advancedtechnology is being applied.

Recycling techniques

All the sites visited were employing manualdismantling to remove hazardous materials(mostly CFC refrigerants; CRTs) and any largecomponents such as drive motors or washingmachine drums. These large componentswere being separately collected for recyclingwith an emphasis being placed upon goodquality of strip-down to give a high purity ofthe recycled material.

The type of plastic components seen to beremoved were:

• Washing machine drums – PP• Large moulded bases and covers for

washing machines – acrylonitrile-butadiene-styrene (ABS)

• Fridge trays and vegetable boxes –polystyrene (PS) or PP

• TV casings and back covers – PS or PP• Air conditioners – covers and fans

In most instances there was an emphasis oncollection of clean components, with effortbeing seen to remove labels and adhered dirt.

Similar plastic types were collected togetherand then diverted to dedicated shreddingmachines to reduce the polymer to ~10 mmchips. This material was then sent off-site forfurther processing.

TV casings were being removed at all sites,but there was no visual evidence of at-lineanalysis of polymer type or any attempt tostream the casings by brominated flame-retardant content. It was stated at twocompanies that up to 60% of the TV casingsdo contain brominated additives. This meansthat the shredded plastic from this particularstream is finding its way into lower-gradeapplications in non-E&E goods.

Of particular note was the use of brominatedplastic generated from the Hitachi plant. Anexample of using the brominated content toprovide flame-retardant benefits was seen inthe production of a cable-tray conduit usedfor the laying of power cables alongsiderailway lines. This is a durable productapplication where the flame-retardantproperties are of continued lifelong benefit.

However, in most cases the quantity ofplastic being manually removed from the fourproduct types was observed to be fairly lowin relation to the total plastic content of theitems. This means that a large proportion ofthe plastic is only released for recycling in thedownstream bulk shredding process.

Most sites were using a similar format ofvertical shredder to size-reduce the strippedbodies or casings. It was judged that heavy,dense components such as drive motors werebeing manually removed prior to shredding inorder to reduce wear on the equipment.

All plants were operating some form of airclassifier or dust blower to remove theurethane foam and other dirt post-shredding.This was then followed by metal recovery usingmagnetic and eddy-current equipment. In themajority of plants the residual stream was a

43

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Page 46: Elektricni i elektronski otpad

mixed plastic material in the form of 5-10 mmshredded chips (Exhibit 10.5). When questionedit was clear that this polymer mix was beingsent for thermal recovery via incineration or asreducing agent at blast furnaces.

There were only two sites where some effortwas being made to separate the polymertypes from the bulk stream:

• METEC – the fridge plastic was fed into adensity separation line that included a high-g spinning disc water cyclone togenerate a good split between the PP andPS materials. It was stated that PVC wasalso being removed, possibly using a highdensity solution method.

• Sony – some form of sink float facility wasin operation to wash and remove PPmaterial (although the final productappeared visually of low quality).

METEC also had a screened-off section of theplant where further plastics separationtechnology was under development. In thedevelopment laboratory the mission teamwere shown samples of high-purity plasticwhich were stated to have positive value forreuse applications.

In all cases it was difficult to make anaccurate assessment of the continuousprocessing systems because they weremostly enclosed in soundproof rooms or onlyable to be viewed from remote galleries.

10.2 Glass recycling

Simple, manual CRT removal was beingapplied at most of the sites. Effort was madeto scrape off labels and excess dirt. The X-ray tube was being manually removed from theCRT cone either with a disc grinder or byusing a file and breaker tube. Minimalconcern was given to the release of phosphorpowders, with one site pouring some waterinto the open hole of the CRT and anotherapplying some sticky tape.

Stripped down CRTs were being stacked incages with blankets to prevent breakage atmost sites. These cages were then shippedto another site for glass recovery.

Only at METEC did the mission observe asystem for CRT splitting. This utilised an in-house design of hot-wire cutter as follows:

• The CRT (less X-ray tube) was fitted ontothe cutting jig

• A camera device raised the tube up to thelevel of the frit (weld) between the coneand the face glass

• A glass cutter arm made a score mark onthe tube as it was rotated, at a level 10 mm from the frit join

• A hot-wire band about 3 mm thick waswound around the tube and heat applied tocause a break on the score line

• After lifting off the cone section and metalshield, a manual vacuum brush was usedto remove the phosphor coating

This type of technology has been furtherdeveloped and is now available commerciallyacross Europe from a range of equipmentsuppliers.

Sony mentioned a process to clean the CRTglass which was able to grind off the graphitecoating from the cone glass, but this was at aremote site.

Exhibit 10.5 Residual mixed plastic chips

Page 47: Elektricni i elektronski otpad

It was commonly stated that CRT glass wasbeing used to manufacture new CRTs,although with the TV market becomingdominated by LCDs and flat screens this maynot be sustainable.

LCD recycling

No LCD TV equipment was seen coming intothe recycling plants, which is strange becausethere must be some broken units enteringthe waste stream. It can only be assumedthat as they do not strictly conform as aHARL product no legal recycling is required.

We saw a large plasma screen stripped downfor assessment in the METEC developmentlaboratory, and Sharp mentioned some workon LCD recycling and indium recovery.

Some laptop LCD displays were separatelystored at both Sony and Hitachi, with somecare being taken to remove the halogen backlights. On questioning we were told theywere destined for incineration. Clearly themercury content was a problem.

10.3 Metal recycling

No novel metal recovery technologies wereseen at any location, with the usualseparation techniques of magnetic, Foucaultand eddy-current separation being used.Clearly density separation used to upgradethe plastic fraction produced a metal-richcontaminated plastic stream.

As some of the major manufacturers in eachGroup have metal production facilities (egMitsubishi), the bulk of novel separation maybe done elsewhere. Thermal recoveries of thevarious fractions were mentioned at varioussites. These included secondary aluminiumsmelter, primary iron and steel with arecycled element and copper refineries usedto recover the precious metal group (PMG)from the associated copper fraction.

As with the plastics fractions, CMR of thevarious metals was considered desirable, andclearly this is in fact easier with metals thanplastics in any case. As many of thecompanies involved have interests in otherconsumer goods, in the transport sector andother manufacturing, finding a friendly partnerwilling to reuse ‘recycled waste material’ isobviously easier than in the UK and Europe.

On a less obvious note, culturally thereseems to be no particular barrier to reusingmaterials from waste in manufacturing newproducts, unlike the UK and continentalEurope. Recycling appears ingrained in theJapanese psyche and consequently there is anatural expectation that products will have ahigh proportion of recycled material. Thedebate about ‘when is a waste not a waste’does not seem to arise in Japan.

The four HARL items contain a number ofdiffering metals that can be recovered;however, the metals need to be separatedtaking into account the depollution concernsand the economic element as well during thedisassembly phase.

The mission was shown how differing metalswere physically separated from plastics as faras economically possible. However, there areoccasions where a particular component ofplastic is bonded to the metal and it would notmake economic sense to separate theseparts. An example is a washing machinecircuit board which is encased, or ‘potted’, inclear plastic so as to eliminate short circuits.

The main parts of all four machines areseparated prior to crushing or shredding, themain metals recovered from each machinebeing as follows:

• Washing machine: steel, aluminium, copper • Television: steel, copper • Air conditioner: steel, copper, aluminium,

cast iron• Fridge: steel, copper, aluminium

45

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Page 48: Elektricni i elektronski otpad

The above metals are separated as theyemerge from the crushing/shredding processand are separated further by varying meansas described above.

Exhibit 10.6 is an illustration of eddy-currentseparation for ferrous and nonferrous metals;this ensures that the material collected is of auniform standard.

Only one company visited dealt with EoL PCBsand that was the Green Cycle Corporation(Sony). All other sites visited sent the PCBsdirectly to smelters for metal recovery. It canonly be assumed that Green Cycle has as oneof its stakeholders a smelter which can absorbthe cost as it is kept in ‘the family’.

Tokyo Eco Recycle even went as far as usingspecialised equipment (Exhibit 10.7) topulverise and reduce the amount of plasticcovering, delivering a higher-grade metal waste.

Ferrous wastes from casings of washingmachines and air conditioner units along withstraps from televisions were reduced to ~30 mm pieces and then sent to steelproducers for processing into new material.

Compressors from fridges are normally keptseparate as they are drained of oil, sent forshredding, and then collected with all theother ferrous metals.

LCD recycling

A brief summary was given of Sharp’s workin the recycling technology for LCD screens.They have developed guidelines for the saferemoval of mercury backlights and removal ofthe liquid crystal material. They appear to beworking on a method to remove indium fromLCD glass by acid dissolution, but detailswere limited. The future goal is to reach100% recycling of LCD TV sets.

Plant-based plastics mixing with PPrecyclates

Use of plant-based polymers is increasing inJapan; examples were shown of a Walkmancasing made from polylactide (PLA).

Sharp has worked on recycling of plant-basedplastics mixed with PP. This gave a problemdue to the noncompatible nature of the twomaterials (one plant-based, one mineral-based). Sharp has developed a compatibliserchemical (a copolymer chain molecule ofpolyester-PLA-polyester) that made the‘particles’ of PLA disperse into the PP matrix.This caused a large improvement in thestrength of the polymer.

Sharp predicts a large increase in the use ofplant-based materials, and these will need tobe compatible with mineral-based polymersfor ease of future recycling.

11 FUTURE TRENDS

Page 50: Elektricni i elektronski otpad

Overview of government, academic andlegislative drivers

There is a clear goal to progress homeappliance and other electronics recycling withinJapan. One of the key reasons is that Japanwill run out of landfill in the near future –however, this needs further investigation dueto conflicting information (eg some companiesquoting the year 2008 and some giving 13.1years of landfill from 2002). Municipal solidwaste (MSW) treatment methods are heavilyskewed to incineration (78.4%) with recycling(17.3%) and landfill (4.3%) coming in secondand third place6 and with home appliancesrepresenting only 2% of MSW7. Othermotivations for accelerating recycling of homeappliance and other electronics includeadvanced knowledge development relative toEurope and North America and ultimatelymedium/longer-term competitive advantage.

‘The Japanese System’ gave Japanesecompanies the confidence and certainty inthe late nineties to make investmentdecisions to build recycling plants andinfrastructure, eg on the basis that the HomeAppliance Recycling Law (HARL) wasimplemented as planned in 2001. In addition,

the requirement that consumers must pay aprimary logistics fee and a recycling fee hasmeant that there is a guaranteed andpredictable income for the corporate ownersof the recycling plants. However, the actualeconomics of the recycling plants are notentirely clear, eg some recycling plants seemto have received capital and other grants fromgovernment. It appears that most of therecycling plants were set up as pilots from1999 and came on stream from 2001,therefore allowing problems to be sorted outbefore coming into full operation.

There seems to be between 42 and 50recycling plants focused on HARL requirements(depending on company definition) – and theseare split between the A and B Groups (quotedas 30 in Group A, 16 in Group B and three jointlyowned). The exact number, geographicaldistribution and types of recycling plants areslightly unclear as they appear to depend ondefinition. There also appears to be 380 take-back sites, 190 controlled by Group A and 190controlled by Group B6.

(televisions, washing machines, air conditionersand refrigerators) are being overachieved as aresult of the ‘buy-in’ from all key stakeholders inJapan, ie consumers, industry and government.It should be noted that the Japanese define therecycling rate as ‘weight of materials recycled’divided by ‘weight of unit treated’6.

In the five recycling plants visited (MatsushitaEco Technology Centre – METEC(Matsushita), Hyper Cycle SystemsCorporation (Mitsubishi Electric), KansaiRecycle Systems (Sharp), Green CycleCorporation (Sony) and Tokyo Eco Recycle(Hitachi)) much of the technology used seemsto be low tech, similar and with a high labourcontent, eg manual disassembly. Many of therecycling plants seem to be using their owntechnologies with several stating that theyhad patented particular processes.

Green Cycle Corporation (Sony) and Tokyo EcoRecycle (Hitachi) seem to be at arm’s lengthfrom their mother companies, ie they arecontractors, with their own profit and loss andbalance sheet responsibilities, whereas METEC(Matsushita) gave the impression of beingmore closely linked to the corporate body.

The ownership of each recycling plant seemsto be dominated by one key shareholder withfinancial contributions from other members ofeither Group A or B, dependent on whichGroup the recycling plant belongs to.

The Law for Promotion of Effective Utilisationof Resources (LPEUR) was also passed in2001 and seems to have much broader remitby product category and coverage, eg itcovers both eco-design and recycling. Forexample, since April 2001 computermanufacturers have been required to designproducts that consider the 3Rs (reduce,reuse, recycle) and are also obliged to collectand recycle end-of-life (EoL) computers frombusiness. Manufacturers have also been

required to collect and recycle computersdischarged from households since October2003. The details and obligations of LPEURwere not highlighted by any of the companiesvisited and this is an area that needs furtherinvestigation especially in relation tocomputers and mobile phone recycling(British Embassy presentation (2005)).

A key learning is that – in effect – the ownersof the recycling plants have had approximatelysix years’ experience of running the ‘recyclingsystems’ for televisions, air conditioners,washing machines and fridges. This ‘recyclingsystem’ includes, for example, the collection,logistics, storage, sorting and recyclinginvolving a range of different stakeholders, egconsumers, retailers, the Post Office,manufacturers, logistics companies andrecyclers. Therefore the key lead that theJapanese have is the knowledge andinformation on how to design, develop andrun recycling systems, infrastructure andplants focused on these product categories.They would interpret this as their ‘intellectualproperty’ (IP) which they could offer to UKalliances and joint ventures (JVs).

There was evidence of advances of eco-design,eg ‘design for disassembly’ (Hitachi) and use of‘automated disassembly used smart materials’(ADSM) for a battery charger (Sharp). Subsequent research would also indicate thatSharp is using similar techniques in the latestflat-panel TVs. Hitachi mentioned that Toshibawas also developing similar software, althoughthis was not covered in the Toshiba visit. Hitachialso highlighted the problem that mainstreamdesign engineers are not always au fait withenvironmental considerations and the challengeof producing tools for non-specialists, eg designengineers generally do not have the time orprimary motivation to be environmental experts,therefore they need simple tools and rules tohelp with decision-making. For furtherinformation see the eco-design mission report8.

There was evidence at Tokyo Eco Recycle thatsome waste products were being convertedinto green products to sell to government inrelation to the requirements of the GreenPurchasing Law (also passed in 2001).

It appeared that only METEC is systematicallypassing new products through a testrecycling system. Green Cycle and Tokyo EcoRecycle both implied that they would be keento do such testing for a fee, but it was nothappening on a continuous basis.

It appears that the METEC facility is ademonstration plant with a very strongemphasis on education and communications.In a similar vein, Tokyo Eco Recycle seems tobe developing a model with a strong focus onproducing high quality, real-time managementinformation possibly as a focus for thedevelopment of a software simulation program.

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Page 53: Elektricni i elektronski otpad

Japan’s household appliance recyclingregulations and the framework in which theyoperate sit in stark contrast to the UK’sdysfunctional approach to the application ofwaste-related legislation. The Japanese havethe advantage of being able to set their owntimetable and structure without theconstraints of Europe that the UK has tooperate within; nevertheless, there wouldseem to be clear lessons that the UK couldlearn from the Japanese approach:

1 Coordinate government departments.There appears to be an acceptanceamongst government departments of theirown roles within legislative developmentwith strong support appearing to be givento lead departments.

2 Industry input. There appears to be amuch closer working relationship betweengovernment departments and the relevantindustries when it comes to creatinglegislation.

3 Timetables. The government would seemto be able to set a clear timetable forimplementation that gives industry theknowledge and certainty to invest in thenecessary infrastructure.

4 Clear strategic aims. There appears to bea well coordinated long-term strategic planin place that avoids reactive knee-jerkpolicies and gives all stakeholders anoverarching understanding of their roles.

It was clear that Japanese society is not so costdriven as the UK and that they seem preparedto overinvest in order to get it right, a culturethat seems to extend throughout Japanesesociety. Whether that can continue, of course,remains to be seen but it was certainlyrefreshing to see a system that seemed moreconcerned about where it was going than abouthow cheaply it could get there.

Plastics technology

In general, the level of plastics recyclingtechnology being employed was not thought tobe of a particularly novel or innovative standard.The exceptions to this were the excellent re-compounding work seen at Sharp and themechanical hydrocyclone displayed at METEC.

Manual dismantling to recover largecomponents of a single, easily identifiedpolymer type was being applied in all plants,although with varying degrees of diligence.The plastic parts seen being removedmanually will probably account for less than10% of the total item mass.

The four products included under HARL arerelatively low in plastic content comparedwith smaller household goods that fall underthe UK legislation. Application of well-provenmetal recovery methods and CRT glassrecycling is able to deliver the majority of therecycling rate needed to achieve theJapanese targets on these four appliances. Inaddition, inclusion of thermal recovery(incineration) as part of the in-house recyclingrate calculation makes it possible forindividual sites to state very high materialrecovery rates.

D.1 International Plastic Fair (IPF)

25 September 2005

On the Sunday preceding the mission someteam members visited Japan IPF 2005. Thiswas held at the Makuhari Messe ExhibitionCentre (Tokyo) across eight halls during 24-28September. In total some 396 exhibitorsacross 2,717 booths were listed and theywere sectioned by halls into specific areas oftechnology and manufacturing.

The mission members were interested insome key questions which were broadlycategorised as follows:

• How many companies are producing and/orsupplying recycled plastics?

• Where is the recovered material comingfrom and in what form?

• Which materials and which markets arethey supplying?

• What equipment and/or technologies are being used and where is it beingsupplied from?

• How many companies are trading partnerswithin Japan and across Asia?

• To what extent are multinationalorganisations represented?

In the time available these were challengingquestions to answer, and information wasnaturally limited to those companies themission members were able to contact.Generally speaking the replies were of anunsatisfactory nature and therefore theseissues merit more detailed investigation.

It was rapidly apparent that very fewcompanies were actually supplying recycledor recovered plastics and even fewer wereproducing them. Some companies claimed tobe in this market but actually were justoffering a ‘compounding’ service, mainly tosupply plastics of a uniform colour andquality. These companies were gaining mostof their materials from virgin redundantfeedstock such as offcuts. Off-spec materialswere also being modified (mainly in productform and colour) and offered as low-grade rawmaterials for other products.

Exhibit D.1 The mission team visit the International Plastic Fair

Page 64: Elektricni i elektronski otpad

The team failed to find anybody offering truerecovered plastic materials from any kind ofEoL recycling operations. After the visits ofthe following week it is clear that this material,limited though it is, is finding its way into thesupply chain via a closed-loop route with theoriginal manufacturers, not the open market.

Where recycled material was being suppliedit was into similar areas as in the UK andEurope. Material substitution was the keymarket such as addition to virgin plastics anduse in low-specification ‘green products’ suchas plastic wood articles.

A vast array of equipment for plasticmanufacture was available from manyvendors, this being the bulk of the exhibitors.Broadly speaking, in the mission’s area ofinterest, the equipment comprisedconventional compounding machines,extruders and shredders. There was evidenceof the better known European machinesbeing available through Japanese and otherAsian franchises.

China was seen as a key market, and anumber of Japanese companies either hadJVs with Chinese companies and/or agencyagreements. It was clear from the exhibition,and the formal visits during the followingweek, that Japan views China as anopportunity rather than a threat. The Japaneseuse China as a cheap manufacturing facility,compared to Japan, and a market for recycledmaterials. After a two-year embargo onexporting waste plastics to China (which hadbeen seen as a dumping ground to allowJapanese companies to claim ‘recycling’targets) the market has been opened upagain. Now China is increasingly being usedas a plastic recycling centre, labour being themain cost in recovering plastic materials fromEoL products. Paradoxically China’s economicgrowth is also providing an indigenousChinese market for recovered materials anddriving material costs in Japan up.

A number of multinational companies wereexhibiting at the exhibition, the majority ofthese being based in the USA or Germany.No UK companies were found in the listingalthough some UK agency suppliers werepresent on the biggest multinational stands.

26 September 2005

The meeting opened with a presentation of abrochure Towards a 3R Oriented SustainableSociety: Legislation and Trends. This brochurewas widely mentioned during the variousmission meetings and forms most of thebackbone of this mission report. Hard copieswere kindly couriered to the UK fordistribution at the mission disseminationevent. An electronic version can be found onthe METI website as a PDF in English.

Subsequent discussions with the group ofMETI officials all from the Department ofInformation and Communication Electronicsestablished the following information.

The Ministry for the Environment isresponsible for enforcing the HARL andLPEUR regulations and the results aremonitored independently by another quasi-government organisation. These results andstatistics are published annually by METI.

Despite the self-evident success of the HARLlegislation, METI currently has no plans toextend the requirements to other appliances.These other appliances are covered byLPEUR (which does not appear to have anytargets associated with it) and are handled bylocal prefectures much the same as in theUK; some charge for disposal, some don’t.These recycling technologies are the standardcrush, shred and bulk separation of metallics.

By common consent the next items that wouldbe included in HARL would be PCs, with afocus being on B2B. Like the UK, mobilephones seem to be a special case and arerecycled by the manufacturers to recover thePMG content.

It is essentially illegal to export non-workingelectronic appliances to China but some‘illegal activity’ goes on. METI estimated thattwo million TVs and several million VCRs wereillegally exported to China via middlemen inSingapore in 2004. Spot checks are carriedout on suspicious consignments todiscourage this trade.

General public awareness of HARL and otherrecycling activity is very high, around 80%,and the government does not consider itnecessary to advertise to raise awareness.The level of recycling activity has significantlyincreased since HARL came into force,including increased recycling of non-HARLappliances. The next huge hurdle is analogueTVs when digital is enforced in 2011.

Page 66: Elektricni i elektronski otpad

Local opposition to recycling plants is low asthey tend to be located in remote locations.(When the mission later visited various sites,they did not appear to be in ‘remotelocations’ – but that may just be down to thedefinition of rural/remote in Japan!)

Incineration of final recyclate is well acceptedand there seems less opposition in Japanthan in Europe, possibly as incinerators areseem as energy-from-waste (EfW) plants andJapan is very energy dependent.

PC recycling marking is in force as part ofLPEUR and those with markings are collectedfor free by the Post Office and delivered tothe manufacturers’ recycling plants. In thecase of unmarked products the consumerpays a fee. The idea is for a highly visible feeon new machines.

The HARL ticketing system is controlled by aquasi not-for-profit organisation called HAPA,which acts like a manufacturing tradeassociation but seems to be under theultimate control of the government. Disposalof old products in the absence of buying anew one is through the original vendor ifknown, otherwise through the ticketingsystem described in Chapter 7.

METI appears to be consulting with Japan’snear neighbours on common strategy for thePacific Rim but to date this has not reallybeen on an official basis. Likewise, dialoguewith the UK and EU has just started. This isbeing driven to some extent by EU legislationlike RoHS which is having a very big impacton Japanese manufacturers.

Headline information as presented by TakashiHishi – President:

• Start of operation – 12 May 1999• Capital build cost – £26 million equivalent • Total site area – ~16,276 m2

• Total floor area – ~13,447 m2

• Transformer substation capacity –1,550 kWh

• Treatment capacity – 1,050,000 units/y ofelectric home appliances (including Kyotobranch) + 400,000 units/y of officeautomation equipment

• No treatment by water or incineration• Recycle of refrigerator insulation CFC• ISO 14001 certification – April 2001

Mitsubishi Electric supports two JVs in Japan,this one in Higashihama and one in Kyoto.

The Higashihama plant does all HARL productsexcept TVs plus some photocopiers andPCs. The Kyoto plant processes TVs as well.

This is due to logistics as Mitsubishi originallymanufactured TVs in the Kyoto region andcould reuse the recycled glass.

Mitsubishi is particularly proud that the plantwas built and commissioned before theHARL legislation came into force. It is alsokeen to promote its two new brand leaders,the ‘Uni’ and ‘Eco’ manufactured units usingthe 3R principles. The Uni (Universal) unitshave the minimum of 3R principlesembedded in them while the Eco units are‘super green’ – using 3R principles in theentire supply chain, manufacturing anddelivery system – and are sold at aconsiderable premium because of this.

Mitsubishi analyses the take-back figures ona monthly basis; there are peaks in July andAugust for fridges and air conditioning units(unsurprisingly), while TVs peak in December.Both phenomena are driven by matchedpeaks in sales of new units. This ability toanalyse take-back figures against new salesis clearly a marketing advantage for the OEMsuppliers in Japan that would be impossibleto emulate in the UK model. This analysisalso allows them to predict labourrequirements and move operators around atpeak times as the different appliance inputsare out of phase.

Mitsubishi uses a horizontal self-recyclingsystem as detailed in Exhibit D.2. As can beseen, disposal to landfill is clearly a very smallfraction. It also claims to not incinerate anyresiduals. However, this is ratherdisingenuous as energy from waste is notclassed as incineration nor when metal isrecovered from ash! In addition, plastics usedas a reluctant additive to the company’s in-house smelting group Mitsubishi Steel alsodon’t count.

However, Hyper Cycle Systems atHigashihama claims to recycle 99% pure PPand reuse all of it in new Mitsubishi products,which is significant. The high-precision plastic

One of the collaborators, Asahi Glass, hasfurther refined the process to recycle therecovered gas into a cleaned product that canbe used in a plastics synthesis plant asshown in Exhibit D.6.

These plastics plants produce Teflon typematerials that are used to coat Mitsubishiproducts such as non-stick electric fish grillsand domestic infrared ovens (Exhibit D.7).

During the plant tour it was apparent thatHyper Cycle Systems has a very integratedprocess with preliminary upstreamseparation being merged into commondownstream unit processes, which isdemonstrated by the flow sheet model inExhibit D.8. This would become a commonfeature of all the site visits.

The company’s representatives were verykeen to point out that the recyclingphilosophy is deeply embedded withinMitsubishi which has a significant ongoingcommitment to ‘design for the environment’principles in its new product design. Anexample of this policy was the fact that thereprocessing unit has a photovoltaic (PV) solarroof which generates a significant amount ofthe energy the unit uses!

Toshiba’s Corporate ManufacturingEngineering Centre is not a recyling facilityand was clearly more involved in productdevelopment R&D, albeit with a knowledgeof manufacturing for EoL recycling. The facilityhas 543 employees, 332 researchers and 81technicians and has been running since 1970.

Core technologies are semiconductors,mechanical components, manufacturinginnovation, quality control procedures,mechatronics, motor/inverter technology, andelectronic components assembly (such as‘flip chip’ and SMT liquid crystals). The facilityalso does rapid prototyping with a PCBmodelling centre, soldering school and valueengineering unit.

Due to the training element it has a strongeducational focus both for its own employeesand the general public (this seemed a strongtheme in all the sites visited by the mission).

The Centre focuses on technologicalsolutions for Toshiba’s manufacturing units.Most of the rest of the visit centred aroundone aspect of this which was its approach tothe lead-free solder problem. While ofspecific commercial interest to a number ofthe mission delegates it is not particularlyrelevant to the objectives of the mission.Consequently these highly technical detailshave been left out of this report.

Most queries on HARL and recycling werereferred to their published literature andsuggestions that we contact their partners inGroup B for more precise details. On thespecific topic of LCD recycling the hostengineers were aware that some researchhad been done in this area but most LCDmaterials were recycled to secondaryaggregate and road surfacing applications.

Clearly Toshiba is active in the area ofrecycling but not at this site, and theassembled people from the EnvironmentalManagement Division were only involvedperipherally. Pre-mission intelligence from UKdelegates indicates that Toshiba is alreadydoing very sensitive confidential R&D intoactive disassembly and possibly did not wantto speak about it in an open forum.

27 September 2005

Following introductions and exchanges ofbusiness cards, the mission team was given ashort presentation by Dr Itoh on the overviewof Hitachi Corporation and the breakdown ofHitachi R&D in Japan and overseas (seewww.hitachi.com/about/corporate/organizationand www.hqrd.hitachi.co.jp/global/organization.cfm).

The Production Engineering ResearchLaboratory (PERL) was established in 1971 inTotsuka-ku in Yokohama and employs 314 staff.Milestones for PERL include a fully automatedassembly line for tape recorders, producing100,000 sets per month in 1980, and winningthe Ohkouchi prize – recognised as the mostprestigious award for production engineeringand technology in Japan. PERL has also wonother awards: 1990-1995 for the developmentof large-scale computers, and 2001 formanufacturing innovation in the PC industry.

Developments now concentrate on thecollaboration between design andmanufacture. The mission was shownevidence of EoL now being factored intothese equations, all part of the Japanese‘Monozukuri’ (the art of making things). Thebasic philosophy is based on the Hitachi LtdStandards of Corporate Conduct (establishedin June 1983). These are intended to setHitachi’s action guidelines for addressingenvironmental conservation in relation to itsbusiness activities, and are a major influenceat PERL which is responsible for evaluatingchemical substances used in products andthe total management system for a ‘recyclingbased society’.

Lead-free soldering technology

The mission was given an insight into PERL’swork on lead-free soldering by Mr MasahideOkamoto. He explained the Hitachi timeframefor the application of lead-free solder:

• 1983 – Hitachi started research into lead-free soldering

• 1999 – lead-free soldering introduced intoHitachi laptops and phased in throughouttheir product lines

• 2002 – all industrial equipment andproducts of all affiliated companies werelead-free

Lead-free solder paste has a higher meltingpoint (260 oC) than conventional Sn-Pb solderpaste (240 oC). Problems occurring during thewave soldering process, such as fillet lifting andcavities caused by shrinkage, were overcomeby rapidly cooling the underside of the PCB.

Mr Okamoto explained the IMS (IntelligentManufacturing Systems) project EFSOT(Environment-Friendly SOldering Technology) –a joint project between Japan, Europe andKorea (Exhibit D.9) – and the timeframesinvolved (Exhibit D.10).

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Page 73: Elektricni i elektronski otpad

The objective of the EFSOT project was todevelop a set of new technologies and adatabase that would enable selection of anoptimum solution for a given application andproduct by identifying such characteristics assolderability, joint reliability, toxicity and –most importantly – the environmental impact

of possible combinations of lead-free soldersincluding those used to metallise the parts tobe soldered prior to actual soldering.

EFSOT was funded (€10 million) by the ECwithin the FP5 Growth Programme under thecontract number G1RD-CT-2002-00838.

Environmentally benign manufacturing

To promote environmental initiatives, HitachiGroup has built an environmentalmanagement system for consolidatedreporting. Hitachi’s Senior ExecutiveCommittee for Environmental Policy, amanagerial level committee chaired by thePresident, assesses and determines theenvironmental policies and strategies for theentire Hitachi Group.

The environmental policies adopted aredelegated to the Environmental ManagementOperations Committee to be implementedand communicated throughout theorganisation. The Environmental Committee(and subcommittees) works to attainenvironmental goals and tasks by conductinginvestigations and developing usefulevaluation methodologies and techniques.

It also establishes the organisations required forimplementing environmental activities in eachbusiness, and designates environmentaloperations officers within Hitachi’s businessgroups, subsidiaries and affiliated companieswho are responsible for managingenvironmental matters within each organisation.

Both within Japan and overseas the HitachiGroup shares information about laws,regulations, market trends, and reports onrelevant topics. From 2005 it has also beenworking to upgrade its environmentalmanagement system in its facilities in Europeand China to promote the sharing ofinformation and enhancement of environmentalactivities within the Group in each location, andplans to implement the same measures in theUSA and other locations.

For its part in this, PERL was responsible fordesigning environmental tools and systemsas part of Hitachi’s ECP (EnvironmentallyConscious Product) objective. Otherresponsibilities included developing lead-freesoldering technologies and chemical

substances management systems, in partdue to EU RoHS legislation, and amanagement system for ‘circulatingmaterials’ in preparation for Japanese andEuropean reuse and recycling laws.

Recyclability Evaluation Method and itsapplication

In 1999 Hitachi introduced a system oflabelling products with environmental impactinformation. Under this system, products soldin Japan had an environmental rating as wellas pertinent environmental data. The newsystem first appeared on PCs launched inDecember of that year.

In 1994 Hitachi drew up a set of standards forassessing products in terms of decreaseduse of resources, recyclability and ease ofdisassembly. In the same year, the companydeveloped and implemented Life CycleAssessment (LCA), DisassemblabilityEvaluation Method (DEM) and RecyclabilityEvaluation Method (REM). As of April 1999,these design tools had been used to developa total of 62 ‘green’ products.

For the new system, products will beevaluated based on a set of criteria forassessing product design in terms ofenvironmental compatibility. A product thatreceives a high assessment score will carry aspecial mark and relevant environmental data.

The mission was given a short explanation ofREM by Dr Toshijiro Ohashi, who said thequantitative attributes of REM are recycleexpense index, estimated value, estimatedrecyclability rate, recyclability/disassemblabilityevaluation score, etc. The goal is to providedesigners with a tool to compare recyclabilityof various design options. The user inputs partname, material and mass, and symbols whichindicate the required disassembly operation.There are some 20 types of disassemblyoperation elements, categorised bymovement, tool operations, etc.

72

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Page 75: Elektricni i elektronski otpad

Examples include upward movement, screwrotation and cutting. Model output includesestimated disassembly time and totalrecycling expense. The system has now beenincorporated with CAD software, so giving aschematic view for disassembly lines.

It appeared that REM was of little use toprocessing plants in Japan as the plants wereprocessing only limited product lines made bythe parent manufacturer.

REM is offered to contracted users athttp://ecoassist.omika.hitachi.co.jp.

Summary

Hitachi has worked in several different areasof environmentally benign manufacturing,including lead-free soldering, evaluationmethods for recycling, inverse manufacturing,and recycling information exchange systems.It has clearly articulated a policy to pursueenvironmentally conscious design andmanufacturing in a variety of areas, andquantified specific goals and target dates.

28 September 2005

After an introduction and welcome by KoFukuda, a DVD presentation was given aboutMatsushita’s commitment to the environmentand the METEC facility itself. The facilityopened in April 2001 on a site already ownedby Matsushita and its cost was given as ¥5 billion (~£25 million). It had the capabilityto process one million units per year. The areain which it was built was famous for growingrice used in saki production.

Matsushita was committed to thedevelopment of green products, as well as torecycling research and technology. It was fullyaligned with the need to reduce, reuse andrecycle (the 3Rs) and to coexist within theglobal environment.

The plant had been commissioned to coincidewith the implementation of HARL andMatsushita had established specific productrecovery points throughout Japan. The plantwas processing the four types of electricalgoods specified in HARL – air conditioners,washing machines, televisions and refrigerators.

In addition to the actual disassembly lines in theplant, there was also an education centre wherethe public – particularly school children – had theopportunity to visit the facility to learn moreabout Matsushita’s recycling activities and theneed to recycle more EoL products. Forexample, the education facility showed andcontrasted the material and component contentof a TV made 20 years ago with one madetoday: the reduction in the number of individualcomponents and materials was significant.

The plant had been built in such a way that itdid not look like a recycling plant from theoutside. Special attention had also been paidto the design in order to reduce noiseemission from the plant: it had beensoundproofed and anti-vibration mountingshad been used on the equipment. Dust anddirt was collected and cleaned or incinerated.

The aim was to make the plant as open tothe community and general public aspossible. METEC also participated in anEnvironmental Council meeting with localresidents every three months.

The recycling processes used in the facilitywere basically the same as might beencountered in other plants but thecleanliness of the whole facility clearlydistinguished it as a showcase recyclingcentre, especially when compared to theother plants visited during the mission.

There appeared to be a large amount ofmanual work undertaken in the plant andthere were a large number of staff workingon the dismantling lines.

The overall process flow in the plant was asshown in Exhibit D.11.

Exhibit D.11 Process flow at METEC

The key part of the whole process was theshredding operation and it appeared thatsome considerable thought had been given tothe design and type of shredder used for

each specific product. The shredders weresurrounded by noise barriers and air wasfiltered before leaving the enclosures.

Following the introduction and DVDpresentation the mission team visited thetraining centre, where more details were givenregarding the recycling of the four types ofproducts handled by the plant. The educationcentre had examples of the types of materialsthat were recycled at the plant, and theapproximate material compositions for eachtype of product are shown in Exhibit D.12.

The recycling rates achieved by METEC weregiven – they are well in excess of theamounts required by HARL (Exhibit D.13).

Details were then given of the recycling ofthe four different products defined by the law.

The first one discussed was televisions and,as can be seen from Exhibit D.12, by far thebiggest proportion of material in a TV is glass.It was stated that CRT glass could berecovered with 99.7% purity and that therecovered glass was used to make newCRTs. The quantity of glass in a typical CRTwas said to be equivalent to the quantityneeded to make 68 drinking glasses.

Because the glass in a CRT varies incomposition between the panel and thefunnel (the funnel glass containing lead forexample), it was critical that the CRT be splitinto two parts at exactly the right place forrecycling. Matsushita had developed a specialcutting machine that used an optical systemto ensure that the CRT was divided at thedesired place. In this process the CRT initiallyhad a groove ground around its circumferenceat the point where it was to be split. A heatedwire tape was than wrapped around the CRTand a current was applied which caused thetape and thus the CRT to heat up locally inthe region of the groove. On cooling, thedifferential contraction of the two types ofglass on either side of the groove caused theCRT to crack into two, giving the panel andfunnel portions. After cleaning, the glass wassent for recycling. However, it wasinteresting to note that the CRT phosphorswere simply removed by suction and thendestroyed by pyrolysis.

The material composition given (Exhibit D.12)for a typical washing machine showed that itwas more than 50% iron and 36% plastic. Thepolymer was mainly PP and this could beobtained in a relatively pure form, via densityseparation, to give a polymer with goodenough quality for use in washing machinebase panel mouldings. It was stated that saltwater was used as ballast rather than concretein many Japanese washing machines, themajority being top loading machines.

Refrigerators were also typically more than50% iron and 40% plastic. One of the keychallenges with refrigerators (and with airconditioners) was the presence of CFCswhich had to be removed and collected sothat they could subsequently be destroyed orconverted into materials suitable for use inthe manufacture of fluoropolymers. Inaddition to the removal of CFCs from thecooling system, they were also removed fromthe polyurethane foam insulation. The oil inthe compressors contained dissolved CFCs

and these were removed by bubbling gasthrough the oil. METEC had also beenworking in a project with the University ofOsaka to develop new methods for removingCFCs from various materials.

Plastic from refrigerators was recycled intonew fridge components such as bottominsect covers and the compressor oil wassent to an oil recycling company where it wasconverted into new lower-grade oil.Compressors were mechanically split toenable aluminium, copper and iron to berecovered. It was also stated that fridgecompressors were treated differently to airconditioning compressors. METEC haddeveloped (with Japanese governmentfunding) a new shredder technology in 1998specifically for compressors and this operatedat room temperature. Recovered metals werepressed into compacted blocks that weresent to a refiner. CFCs were also removedfrom air conditioner units and each individualtype of CFC was separately collected. Themost common refrigerant gas was R22; thequantities of R502 and R134 encounteredwere small and decreasing. METEC isshredding 80,000 fridges each year.

A water-based centrifugal separationtechnology was being used to separateindividual components in a mixed plasticwaste stream. Specifically, PS with its higherdensity could be separated from PP. The unitused at METEC had a 500 kg/h capacity.

Different types of shredders were used forspecific items, for example a vertical spinningshredder was used for refrigerators while atwo axis, twin-shaft wheel shredder wasused for washing machines. The washingmachine shredder was supplied by Kubotaand the fridge shredder by Kinki(www.kinkikogyo.co.jp).

The facility also had a development area thatwas used for company internal R&D andtraining work. Examples of a range of

76

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Page 79: Elektricni i elektronski otpad

recovered materials were shown and thesewere given red or green labels depending onwhether or not they could be sold. Work wascarried out on materials that couldn’t be soldto upgrade them. The Japanese governmenthad funded a project to add value to CRTglass. This project had been successful andthe technology had subsequently beendeployed around Japan.

Design engineers are trained at thedevelopment facility to make sure that theyunderstand dismantling and recycling. Thefacility used formal training tools and it alsohad small compact shredders that were usedfor evaluations on new products. There was alot of information in the facility about lead-freeassembly and soldering. METEC had alsoproduced a book called HazardousSubstances Non-use Techno School Book andit was printed in both Japanese and English.

METEC is increasingly thinking about futureproducts and gave the example of a newfridge design which they would dismantlenow, so that they would already understandhow to handle it at EoL.

Work was also being carried out in theexperimental laboratory on the treatment ofoxidised solder (solder dross). Sesame seedswere being used to reduce the oxidisedsolder back to metals.

A presentation was given on HARL. This law,which came into force in 2001, established asocially acceptable recycling scheme thataimed to minimise recycling costs and whichhad convenient logistics. The system that hadevolved was characterised by cooperationbetween local recyclers using their existinginfrastructure and a decentralised recyclingnetwork. Although the law covered TVs, therewas no obligation to process CRT-basedmonitors from PCs; they were veryoccasionally processed at the plant but theywere typically handled elsewhere.

It was asked if HARL covered non-CRT basedTVs, ie LCD. These were not currentlyincluded in the law, but it was likely that theywould be added in the future.

Overall this was a very interesting visit towhat was clearly a showcase demonstrationfacility. The actual equipment used in theprocessing of the four types of EoL productswas not particularly novel and was similar tothat seen at other plants visited. Some workhad clearly been done to optimise shredderperformance for the most appropriate type ofdesign to be applied to each product. Themain feature of this plant was not so muchthe technology but the fact that it wasrunning efficiently as part of an effectiveintegrated process that began with theconsumer and ended with the recycler. Thewhole mechanism had been initiated byHARL and it was clear that, despite thecharging of fees for recycling EoL appliances,the Japanese public were willing to play theirpart in making the process work. It is difficultto imagine a similar process being sosuccessful in the UK for numerous reasonsincluding cultural ones.

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

The following summary of the operation isbased upon the presentations and theobservations of the mission team during thefactory tour.

In the limited time available, the PlantManager concentrated upon the following:

1 Freon gas removal and monitoringsystem – A semiautomated system hasbeen implemented to ensure that allrefrigerant gases collected from airconditioning and fridge equipment iscorrectly recorded and stored in separatetransport containers. Each individual unitis bar-coded into the gas-removal sectionand the model and serial number used toascertain the type of Freon gas used(often this is also clearly marked on thecompressor/gas system).

During gas removal the weight of the unitis monitored and gas extraction can onlybe stopped once there is no furtherdetected drop in mass. A system ofwarning/signal lamps is used to informthe process operator when it is safe tounhook the gas extract clamp from eachitem. Much effort was given to separatestorage of the different gas types – whichwas explained as being needed to satisfy‘gas storage’ laws, but this seemsunnecessary if all hydrochlorofluorocarbon(HCFC) gases are being sent for thermaldestruction.

2 Plant inventory and material flowcontrol system – Explanation was givenof the information technology (IT) systemthat records the data from each unitentering the plant and links this to themass flows of material leaving thefactory. Real-time stock control and work-in-process (WIP) monitoring wasincluded. There appeared to be nothingnovel here, other than all incoming unitswere seen to be clearly marked with theconsumer’s shipping ticket which formed

the key to the whole system, evenallowing individual trace-back by item forthe original disposer.

3 Plastic recycling – There was briefmention of the plastic from washingmachine tubs being recycled since 2001back into new parts for Sharp washingmachines. TV cases and fridge base platesetc are being sent for recycling into otherlow-grade goods; this is thought to be dueto the high incidence of brominated flame-retardant additives (see following visitreport on Green Cycle Corporation).

4 Plant flow sheet – A block flow diagramof the main unit operations carried out inthe plant (Exhibit D.17) shows the initialmanual disassembly operation on fourlines dedicated to each product, withremoval of large items (eg CRTs, motors,big plastic parts) and Freon gasextraction. CRTs are sent for processingat a remote site after removal of copperyoke and X-ray gun. Sticky tape is usedto prevent escape of phosphor powders.

After the manual strip-down of the unitsis complete, the material is sent forshredding in a soundproof, enclosedroom. The fridge and washing machinehousings are sent to two similarshredders (vertical shaft design, made byKyboto). These units incorporate twoshredding regions: the first gives ahammer-mill effect using breaker barsand stators; smaller pieces then fall intoan annulus gap between the rotor andthe shredder wall to undergo further sizereduction down to about 10-25 mm. Thisdesign has the advantage of allowingcontinuous operation, with gravity infeedand output of materials. Sharp providedtechnical data on this unit together withinformation on the lifetime of the primarywear parts (330,000 units processed ineight months between replacement ofbreaker-bar and stator plates).

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

The fridge-body shredder feeds the metal,plastic and urethane-foam mixture to an airblower that removes the lighter insulationfoam waste. This material is sent forthermal destruction following compressionin an extruder to form pellets.

Magnetic and eddy-current separatorsare then used to reclaim the metalfractions, and the remaining mixed plasticwaste is sent for external recycling. Themixed plastic has been sent for thermalrecovery at incineration plants, but thismay be linked to mention of a lawbanning export of waste to China for thelast 18 months.

During questioning Mr Yoshino quoted thefollowing figures for dismantling labour acrosseach of the appliances:

The plant handles 3,600 units daily with astaff of 85 people on a 12-hour shift pattern.The average time to dismantle each unit is as follows:

• Television – 9 minutes• Fridge – 12 minutes• Air conditioner – 24 minutes

(more Freon to extract)

The mission arrived at the plant to be met byMr Saito, Mr Hori and Mr Tokita and shown toa conference area to be given a shortpresentation on the ethos of Sony and theGreen Cycle Corporation which may besummarised as follows:

• Efficient plant with the simplest layout • High recycling ratio of 98% or more of

CRT glass• High recovery of 93% or more for adiabatic

CFC and cyclopentane• Aiming at high plastics recycling ratio by

the introduction of a plastics separator• High recycling ratio of 80% or more by

using wet-type separator plant with noiseand dust proofing

The visitors were shown round by Mr Tokitaand taken to a viewing platform where theywere able to see television and air conditionerdisassembly lines.

They were also told of the recording of datacollected from the redundant units that aresent to the plant. These data were evident on all equipment that was entering the plantas a sticker (ticket) was attached to everyitem collected (see Chapter 7 for details ofthis system).

Television recycling

This semiautomated plant is fed by fork-lifttrucks depositing units onto a roller conveyorfeeding differing work stations. The variousstages of disassembly are:

1 The units are checked into the system byscanning in the bar code on the returnticket attached to the unit.

2 Differing components are manuallystripped from the unit: first the externalpower supply and then the deflection yoke,speaker, degaussing coil, PCB and cabinet.All are separated into discrete bins.

3 There does not appear to be any check on whether the plastic is flame retardantor not and so it is assumed that it ismixed, as it is put in for shredding with allother plastics.

4 The neck of the CRT to which the gun isattached is removed by angle grinder;there was no evidence of water beingadded to the inside of the tube at thispoint as had been seen at the Hitachiplant visited earlier in the week. Heretape was put over the opening to stop thephosphor escaping.

5 The CRT is then sent down the line andcleaned of most of the carbon grime it hasaccumulated over its lifetime in use. This isaccomplished by use of a small hand-heldangle grinder fitted with an abrasive mop.

6 After thorough cleaning the whole CRT isplaced (not thrown!) into a cage and eachlayer covered by thick sheeting.

This was the first time the mission team hadseen such care being taken with CRTs. Bytiming the process it was found that eachoperator took a full three minutes to cleanone unit.

Air conditioner recycling

The largest volume of any of the recycleditems was the air conditioner units. With theclimate in Japan these are used in virtuallyevery home and so tend to be more inevidence than other equipment.

The units arrive from the extensivestockyards where they are stored and aredeposited by fork-lift truck onto a poweredconveyor system. Then they are dealt withmanually as the self-propelled conveyorsystem gives way to a roller system asillustrated in Exhibit D.26.

Exhibit D.27 Processing of air conditioners at Green Cycle plant (arrows indicate removal of Freon gas)

Page 91: Elektricni i elektronski otpad

The process is as follows:

1 First, as with all recycled equipment, thebar code is scanned on the return ticket sothe particular unit is recorded as havingbeen received for recycling.

2 The units then undergo depollution asillustrated in Exhibit D.27 to remove allCFCs, namely Freon gas which is stored incontainers. This is regulated by anoperative who monitors the amount takenfrom each unit and ensures that each unitis empty before disconnection. The gas isthen sent for incineration as it cannot beused for any other purpose.

3 The power cord is severed and placed in a bin.

4 The outer case is detached using air-powered screwdrivers.

5 At the same station the outer case isseparated into metal and plastic grill. This isnormally achieved by prising the two apartwith a large hand-held screwdriver! Thecomponents are then placed into differingbins appropriate to their composition(metal/plastic). This was the norm at allplants visited.

6 Once the unit is exposed, the piping, heatexchanger, condenser and compressor areremoved and placed into their respectivebins, being sent off site for furthertreatment.

7 Other plastic components, such as theplastic drum, are separated on site.

All of the metal components (other than heatexchanger, condenser and compressor) aretaken directly to bins to be processed off site.

The remaining material is dealt with on site inthe two spindle horizontal crushers, the plasticsbeing sent to the dedicated crusher on site.

Washing machine recycling

The next line shown to the mission was thewashing machine disassembly process. Thiswas by far the dirtiest recycling process of alland was similar at all facilities visited.

In Japan most washing machines are toploading not front loading as in the UK (ExhibitD.29). Also it would seem that the majority ofdrums are plastic instead of stainless steel.

89

WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE): INNOVATING NOVEL RECOVERY AND RECYCLING TECHNOLOGIES IN JAPAN

Exhibit D.29 Comparison of typical UK and Japanese washing machines: (a) UK model – front loading; (b) Japanese models – top loading

Page 92: Elektricni i elektronski otpad

The disassembly process is as follows:

1 The units arrive as all recycled unitspreviously described and have the plasticlids removed from the top of the unit.

2 Then the waste pipe is removed and anyexternal fixings from the bottom of the unit.

3 The unit is then turned over manually andthe washing drum is detached by using anair chisel.

4 The drum is then separated from themotor. At Green Cycle this is done in eitherof two ways. One method is by air chiselto sever the fixing bolts but we were alsoshown a ‘separating booth’ in which thedrum could be placed into a jig and a sawblade used to cut though the fixingsautomatically. This was not in use at thetime but was obviously used in ‘campaignstyle’. The problem with this particularrecycling method is waste water but wewere told that all waste water is treatedbefore release.

5 The drum and motor plus any fixings beingremoved, the drum is then sent to thededicated plastics crusher if it is plastic (in most cases it is) or, if metal, the normal procedure is to crush it under ahydraulic press to reduce the volume forfurther processing.

Fridge recycling

The next line was the fridge section. Theprocess is as follows:

1 The fridges arrive, as with all otherequipment, but with the difference thatspecial air suction lifting equipment isemployed to lift and orientate the units.

2 The unit’s bar code is recorded from thereturn ticket.

3 The unit is stripped internally of all loosedrawers and shelves.

4 The outside magnetic strip surrounding thedoor is removed.

5 The compressor is removed and drained of oil(the oil is apparently commonly of vegetableorigin and is sent for separate recovery).

6 This unit is then sent directly to a verticalshredder.

7 Certain fridges/freezers have a heat shieldon the back which is aluminium and has tobe manually removed. This is undertakenby using a large bar (Exhibit D.30) beforebeing sent to the vertical shredder.

Conclusions

• Plastics

Plastics were seen to be fractionated andsubjected to a washing process although theydid not appear to be of any greater valuevisually than those seen at other plants ascan be seen from Exhibit D.31. Thisfractionated plastic is roughly 10 mm in size.

• Facility

The facility itself was obviously not purpose builtand was probably an old fabrication shop as thearea around it was of old ‘heavy industry’ origin.The stockyard was very large and appeared tobe very pleasant to work in with plants andshrubs in evidence. This was a common featureof site visits and goes to show how the workersare not forgotten but made to feel fortunate towork in such an environment.

• Shredder/crusher technology

The equipment seen at the Green Cyclefacility was two spindle crushers which dealtwith all metal waste. After being roughlycrushed in the two spindle crushers it is finelycrushed in a vertical crusher. Although fridgesare fed directly into the vertical crusher thereis a dedicated plastics crusher.

• CRTs

The form of recycling for this type of itemvaried from plant to plant but it was noted thatGreen Cycle went to greater lengths to achievea much cleaner end product. They claim tohave had the ‘World’s First TV Cathode TubeRecycling System’. From looking at theinformation in a brochure this system wouldseem to be fully automated but unfortunately it

was not located on the site visited. One of theGreen Cycle stakeholders is Nihon Cullet CoLtd so it follows that they would need tomaximise the facility to receive good qualityglass for recycling.

One point they were happy to tell the missionwas that they did export in the region of10,000 old television units to China each year.

• Air conditioners

The air conditioner units the mission saw atthis plant seemed to be treated in much thesame way as elsewhere and the samedisassembly systems were used.

• Washing machines

The difference in how Green Cycle and otherrecyclers treat washing machines is themanner in which the motor and fixings areremoved: Green Cycle uses a semiautomaticcutter while others use semiautomatic pullers.

• Fridges

All of the facilities visited were treating thefridge in much the same way and seemed tobe very proficient at doing so; the one majorproblem component for recycling was themagnetic sealing strip on the door.

• Workforce

It has to be said that the workforce in every company visited was very wellorganised and extremely well motivated;Green Cycle was however the only companyto hire in its workforce on a short-term basis,meaning that they were presumably all ontemporary contracts.

• PCBs

The Green Cycle plant was the only facilityvisited by the mission to actually shred circuitboards on site. This may be due to the fact

Exhibit D.31 Fractionated plastic at Green Cycle plant

Page 94: Elektricni i elektronski otpad

that they have shareholders in the facility todeal with the recovery of precious metalswithin the group.

Dr Kenji Baba President and CEO

Mr Motto Uno General ManagerDepartment of Environmental Business and Technology

30 September 2005

Tokyo Eco Recycle Co Ltd was established in1999 as a corporate response to HARL. In2004 its rate of recycling for four consumerelectronic goods of commercial value(televisions, refrigerators, washing machinesand air conditioners) exceeded thegovernment standards by a wide margin, andthe company achieved zero emissions tolandfill for the third consecutive year.

In 2005 the company won the ninth HondaPrize for Recycling Technology Development,for achieving zero emissions in the householdelectrical appliance recycling division.

HARL was enacted with the goal ofencouraging the efficient use of resources.Tokyo Eco Recycle handles about one-quarterof the volume of the four categories of itemscovered under the Law. The company handlesabout 300,000 items per year in Tokyo, and in2003 sent only 0.1% of the total to landfill,meaning that in effect it achieved ‘zeroemissions’ of waste.

The site is located at nearby Wakasu Park andcampsite, popular with Tokyo residents, andwas therefore subject to strict noise,vibration, odour and dust emission controls.Takenaka (the corporation responsible fordesign and construction) was responsible fornegotiations with various governmentagencies and advisory councils with regard tospecific laws and regulations.

The Hitachi process was applied to five plantsin Japan. Hitachi founded three newcompanies for recycling home electricappliances in Hokkaido, Tokyo and Tochigibased on this process.

President and CEO Dr Kenji Baba introducedthe mission to Tokyo Eco Recycle. He startedby explaining the origins of HARL and LPEUR,stemming from the 1994 Basic EnvironmentalLaw, and the development to the Basic Lawfor Promoting the Creation of a Recycle-Oriented Society of 2001. He went on toexplain how the fees and the manifestsystem worked, and how consumers couldfollow (via the website) appliances throughthis system to the point where the appliancewas recycled.

The definition of the recycling rate, which isdetermined by the law, was given as:

Recycled valuables (t)Recycling rate =

Initial weight (t)

Exhibit D.32 Tokyo Eco Recycle site

Page 96: Elektricni i elektronski otpad

Each product has its own target recycling rate:

• Television – 55%• Refrigerator – 50%• Washing machine – 50%• Air conditioner – 60%

Tokyo Eco Recycle achieves 70% recyclingrate as an average on all product lines.

There are monthly fluctuations in the numberof home appliances recovered for recycling inJapan, the hotter months seeing an increasein refrigeration and air conditioning units, forobvious reasons. Also, the Japaneseworkforce purchasing new products withbonuses earned at work causes peaks inDecember and January (Exhibit D.34).

Key facts about the site at Wakasu are:

• Established – 22 November 1999• Capital investment – ¥300 million

(~£1.5 million)• Shareholders – Hitachi 48%, Ariake Kogyo

34%, Hitachi Home & Life 3%, Mitsubishi3%, Sharp 3%, Sanyo 3%, Sony 3%,Fujitsu General 3%

Recycling process

Processing at Tokyo Eco Recycle starts withproduct identification by utilising the bar codeon the manifest attached to the appliance.The appliance is then weighed.

Products are then dismantled by hand,valuable resources are reclaimed andhazardous materials separated out. Theremainder is processed using technologysimilar to that seen in all the plants visited;however, the vertical shredder used, made byKinki, has undergone modifications. Thesemodifications were requested by Hitachi,which now holds the patent on the modifiedshredder. The whole system is monitored byan ‘operation and management supportinformation system’ which integrates themultiple databases used.

Planning and status reports of goods arriving,treatment and remaining stock are updatedevery 30 minutes. A full flow report isproduced the following day. With information

collected regarding container stock, daily workefficiency and daily CFC recovery monitoringcombined, this produces sufficient informationfor policymaking and operational planning onan hourly, daily and monthly basis.

Single type polymer reclamation is becomingmore important. Single type polymers used insalad crispers from refrigeration units andwashing machine components are set asideand processed through a separate shreddingsystem and washed, to produce single typepolymers for remoulding into new componentparts for products such as washing machinebases and air conditioning covers.

99.8% of materials such as ferrous, stainlesssteel, copper and aluminium are recycled, andrefrigerant gas is incinerated; less than 0.1%is landfilled at Tokyo Eco Recycle.

Polymers not separated for reuse can also beincinerated; this material is then used forroadbed, or incinerated ash becomes rawmaterial for cement based products.

Page 98: Elektricni i elektronski otpad

Foam from refrigeration units is now sold tothe Japanese government for insulationmaterials on low-cost housing projects and toassist in complying with Green Procurementlegislation.

The next issue for the company is therecycling of resources. In Japan the 20th

century was the time of ‘incineration andlandfill’; the 21st century is ‘recycling ofresources,’ not only from waste recycling butthe overall impact on the environment,packaging, transport, etc.

After a short video presentation on the workingsat Tokyo Eco Recycle, the mission team wereshown the process from a viewing gallerywhere they were allowed to take pictures.

In a secure room, accessed by fingerprintidentification system, they were shown PCand gaming machine processing. It waspolicy to destroy information recordingdevices such as hard drives; removed harddrives were placed in a container whichpunctured the device in four places, givingreassurance to end users with regard to datadestruction (Exhibit D.36).

Summary

Tokyo Eco Recycle was set up as ademonstration plant between 1995 and 1998, part-funded by METI and the AEHA.The system was established in collaborationwith government, investors (from Group B companies) and local wastemanagement companies.

The knowledge and experience of thecompany will be a great benefit to governmentand industry in Europe to obtain complianceunder the WEEE directive and otherenvironmental and sustainability policies.

All indications were that Tokyo Eco Recycleand other processing plants wereinvestigating the possibilities and economicdrivers associated with polymer typeseparation from a mixed plastic wasteassociated with EoL electrical products.

Great emphasis was attached to manualpretreatment of products to add value tomaterial arisings, more effective materialseparation, and the protection of theworkforce and Japanese society generally.

Recycling is not a dirty word in Japan

Much has been made over recent years ofhow clean and tidy Japan is compared toEurope and the UK in particular. Japan is avery forward looking nation, identifying theproblem of resource productivity early andthen embarking on a national programme ofeducating people into recycling of waste.

Clearly there is a cultural difference thatpervades all aspects of Japanese society.More difficult is to understand how this hasbeen handed on to the younger generation.The area of recycling electronic scrap gives aclear insight into one powerful mechanism:long-term education.

All of the sites visited had education facilitieswhich were used to tell people about thebenefits and positive impact that recyclinghave on everyday life. Clearly this is notentirely philanthropic; there is a publicityaspect to this as they are manufacturers aswell as recyclers. Also, by law, any profitgenerated from the recycling fees has to bereinvested in the HARL process. However, itis also clear that most companies arepassionate about getting the 3R principlesacross.

Matsushita Electric, best known for itsPanasonic brand, has led the way through itsadvanced recycling plant in the westernJapanese town of Yashiro. The MatsushitaEco Technology Centre (METEC) came intobeing after the Japanese government passedtough recycling measures that came intoeffect in 2001.

Exhibit E.1 METEC facility

Focusing on METEC shows what one plantalone can achieve and what we should aspireto in the UK.

Exhibit E.2 shows a particular demonstrationunit at METEC aimed at children. Themachine, as can be seen from thephotograph, demonstrates the separation ofdiffering materials by weight. In the high-volume airflow, the light balls are sent directlyacross while the heavier ones fall to thebottom. The subject is treated as a fun activityrather than a straight teaching method. Themachine that is used is clearly not expensiveto build and the simple design can very easilybe explained to an audience of young children.The clever part in the demonstration is thatthe children are invited to interact with theequipment for themselves.

All the balls have differing symbols inJapanese representing the different materials,mainly plastics. This simple unit adds interestand meaning for the children who havepreviously been given a factory tour. It allowsthe children to be able to understand in theirown way how the plastic recycling machinerythey have just been shown in the factoryactually works.

This is also the case with the nextdemonstrator shown in Exhibit E.3 whichdeals with magnetic and nonmagnetic items,as seen in the plant where the fridges andwashing machines are shredded and thedifferent metals are separated.

Small magnetic and nonmagnetic bolts aredropped into the hopper. The magnetic boltsare attracted to the wheel and after half arevolution are dislodged by the blade, thenonmagnetic bolts falling straight through.

Exhibit E.4 shows individual letters fromschool children who have visited the facilityon a school trip expressly to understand theneed for recycling. There are also severalpublications that back up the demonstrationunit, one of which is mentioned in this report.

While units of this education type exist in theUK in places such as the Science Museumand elsewhere, being able to see the full-scale units in operation dismantling TVs,washing machines and fridges as at METECgives them added impact.

For more information about METEC see linkwww.panasonic.co.jp/eco/en/metec.

Proof of education in action

The recycling ethos extends into everyday lifewith virtually every drinks dispenser having abuilt-in collection point for bottles and cans. Inmost stores there are facilities for recyclingpaper, plastic and even batteries.

Another example is a cleaning crew sortingwaste from a train that has just been cleaned(Exhibit E.7). As can be seen from thephotographs the Japanese have decided thatindustry should take the lead. This is part ofthe normal train cleaning process tosegregate waste – every train undergoes thisprocess each time it returns to the terminus(maybe another differentiating experience forMr Branson to emulate!)
