ABSTRACT The electronic industry is the world’s largest and

fastest growing manufacturing industry in the world. Discarded electronic and electrical equipment with all of their peripherals at the end of life is termed e-waste. The quantity of e-waste generated in developed countries equals 2% of total solid waste on an average and is expected to grow to 6% by 2016 and is one of the fastest growing waste streams.

E-wastes are considered dangerous. However these products can be reused, refurbished, or recycled in an environmentally sound manner so that they are less harmful to the ecosystem.

This presentation gives an overview of the action plan of e-waste management i.e the hazards of e-wastes, the need for it's appropriate management and options that can be implemented.

What is E-Waste? Discarded electronic and

electrical equipment with all of their peripherals at the end of life is termed as

E-waste. Such electronics goods may

be television, telephones, radios, computers, printers, fax machines, DVDs and CDs etc.

Small Household Appliances

Consumer & Lighting Equipments

Electrical & Electronic Tools

Toys, Leisure & Sports Equipment

Medical Devices

Telecommunication Waste:• Mobile phones• Telephones• Telephone exchanges Wireless Equipment cables and related scrap material• PC and TV

Electrical Waste:

• Switches• Relays• Connectors and related Scrap Material.

Electronic Waste:• Electronic – metal waste• Printed Circuit Boards• E – Equipment and Machinery• IC• Sockets Connectors.

Cable Waste:

• PVC• Pre Insulated Copper and Aluminium Cable waste.

IS E-WASTE HAZARDOUS? Electronics products like computers and cell

phones contain a lot of different toxins. For example, Cathode Ray Tubes (CRTs)

contain heavy metals such as Lead, Barium and Cadmium, which can damage human nervous and respiratory system if they enter the water system.

EFFECTS OF E-WASTE On Environment: On Human Health:* Pollution of Ground-Water. * DNA damage.* Acidification of soil. * Lung Cancer.* Air Pollution. * Damage to heart, liver and

* E-Waste accounts for 40 % spleen. of the lead and 75 percent * Chronic damage to the brain. of the heavy metals found * Asthmatic bronchitis. in landfills.

SOUND E-WASTE MANAGEMENTThe major components of E-waste Management are :- E-waste collection, sorting and transportation. E-waste recycling.

In industries, management of E-waste is done by Waste

Minimization Techniques. It involves:- Inventory management, Production-process modification, Volume reduction, Recovery and reuse. 9

RECYCLING OF E-WASTE Treatment Options of E-Waste are:

a)Land Filling,

b)Incineration. Technology currently used in India is : a)Decontamination

b)Dismantling

c)Pulverization/Hammering

d)Shredding

e)Density separation using water. 1012/04/2014

Reusing and

recycling• Increase

life span of product

Landfills

• Leaching problem (70% of Heavy metals in landfills are because of E-waste)

Incineration

• Fumes of Heavy metals released in atmosphere

• Municipal incinerators are giving dioxins

E-WASTE ISSUES & CHALLENGES Accurate figures not available for rapidly

increasing e-waste volumes generated domestically and by imports.

Low level of awareness among manufacturers and consumers of the hazards of incorrect e-waste disposal.

Major portion of e-waste is processed by the informal (unorganized) sector using rudimentary techniques.

E-Waste Issues and Challenges

Leaching of heavy metals from Landfills

and Incinerators

Exposure to workers &

communities

Unawareness (brand new

items are also kept in waste)

HOW TO PROPERLY DISPOSE OUR E-WASTE

Donate working older equipment to schools colleges or government entities in need.

If PC are out of order then return it to the manufacturers. (HCL and Wipro in India has best take back service)

Send waste goods to authorised recycling facility for proper disposal.

RESPONSIBILITY & ROLE ofIndustries:Manufacturers, distributors, and retailers

should undertake the responsibility of recycling/disposal of their own products.

Manufacturers must be responsible for educating consumers regarding the potential threat posed by their products.

Companies should adopt Waste Minimizing Techniques.

1712/04/2014

RESPONSIBILITY & ROLE ofCitizens: E-wastes should never be disposed with garbage and

other household wastes. Customers should opt for upgrading their electronic

items to the latest versions rather than buying new. While buying electronic products consumers should

opt for those that: i. are made with fewer toxic constituents. ii. use recycled content. iii. are energy efficient.

LEGISLATION Basel convention for regulating trans-

boundary movement. The hazardous waste (management and

handling) rules, 1998 as amended in 2008. Municipal solid waste management and

handling rules for non-toxic content. The Environment Protection Act - Biomedical

Wastes (M&H) Rules 1998, Batteries (M&H) Rules 2001, etc.

CONCLUSIONS Solid waste management becoming more

complicated by the invasion of e-waste, particularly computer waste.

Establishment of e-waste collection, exchange and recycling centers should be encouraged.

Policy level interventions should include development of e-waste regulation, control of import and export of e-wastes.
