Transition to a green economy is expectedto deliver a sustainable future with anoptimised ecological footprint globally. Indiais a developing nation with finite naturalresources. As a result, there are sustainabilitychallenges associated with growth.Examining newer processes andtechnologies from a green perspectivebefore deciding upon business strategies,adopting greener products, supply chainand services are part of the opportunities.Adoption of a clean and green way of life iswhere future lies. This paradigm shift to agreen economy offers an opportunity toreview current practices and realign the waywe live to ensure a sustainable future.

Thinking beyond our generation whileexercising options and pursuingstrategies veering round a greeneconomy apparently looks expensivewith a short term outlook since onlydirect costs are taken into account. Wehave limited tools to assess indirectcosts (e.g. health, resourceconservation, environment impactetc). Therefore, businesses face thechallenge to balance the marketcompetitiveness with implementationof strategies in pursuit of a greeneconomy, while at national level thechallenge is to strike the optimalbalance in the deployment ofresources for current requirements andfor sustainable development.Choosing the right indicator in thisregard to track whether we areheading in the right direction is also a

major challenge.

Sustainability is embedded in thebusiness philosophy of Tata Group.Internally, business strategies andgrowth aspirations can be reviewed toaddress emerging needs. Externally,we as an industry can develop a betterunderstanding of the green economyand collaborate with local and regionalpolicy makers to take the right steps

in shaping the future. We can engagein capacity building throughawareness campaigns to directly aswell as indirectly promote a greeneconomy. We need to examine thenuclear and renewable energy sectorsin India (when it opens up) and abroadfor investment and engagement inCarbon Capture and IGCC-liketechnologies.

Challenges to advancing

a Green Economy

03

Over the years, Tata Steel has adopted clean technology to reduce pollution levels. Some of them areas follows:a) Coke Dry Quenching at Coke Plantb) Conversion of all Coal Fired Boilers to Gas Fired Boilersc) Top Recovery Turbine for Blast Furnacesd) Waste heat recovery from waste gases of stoves at Blast Furnaces

Adoption of BestAvailable Technology

b) Conversion of coal fired boilers to By-product Gas FiringThe coal fired boilers cause air pollution and generate huge amount of solid waste. Air pollution controland ash disposal from these units was a major concern. Tata Steel took up this challenge and convertedboilers to by-product gas fired (Blast Furnace, Coke Oven and LD Gases). Gas fired boilers are eco-friendly.This has resulted in reduction of middling (boiler coal) consumption from 1.33 MTPA in FY 98 to around0.1 MTPA currently as presented below.

a) Coke Dry Quenching (CDQ)The conventional wet coke quenching, where water is sprayed on red hot coke is replaced with dryquenching with nitrogen. The major environmental benefit from CDQ is recovery of heat to producesteam and power. Approximate Waste Heat Recovery for 1 MTPA Coke is 0.3 MGCal/annum. This resultsin a CO2 emission reduction of 0.2 MTPA.

c) Installation of Top gas Recovery Turbine (TRT) at Blast FurnacesA turbine was retrofitted in the top gas duct of 'G' Blastfurnace to utilise the gas pressure for running it.Additionally 'H' Blast Furnace was commissioned with anew TRT. Together, these TRTs produce 18-19 MW ofelectricity. As a result of power generation from wastepressure, it helps in offsetting CO2 emission of 150,000tonnes /annum due to avoidance of fossil fuel onsumption.The new Blast Furnaces will also have TRT of approx. 15MW capacity.

d) Waste Heat Recovery in Blast Furnace StoveThe waste heat from hot flue gas of stoves at Blast Furnaces'G' & 'H' is recovered to preheat the incoming air andgaseous fuel to enhance flame temperature to enablehigher dome temperature. This has resulted in increasedhot blast temperature and thus reduction of carbon ratein Iron Making. The amount of heat recovered is estimatedto be 0.2 MGCal/annum and consequential CO2 emissionreduction is approximately 0.1MTPA as a result of reducedcarbon consumption in Blast Furnaces.

Additionally, Tata Steel has been aggressively promotinggreenery development in and around the Steel Works.Some of the initiatives are mentioned below.

a) Jugsalai Muck Dumpb) Compost Plant for Municipal Waste at Jubilee Park

c) Compost Plant for Canteen Waste at Works

During the last fiscal, Tata Steel has taken several uniquesteps at its Works to ensure that the ecology of thearea gains further in its green cover.

Organic compositing Plant for canteenwastesThe Organic Waste Convertor machine installedat Tata Steel Works will treat wastes collectedfrom its 16 canteens, bio-mechanically, and willgenerate 400 Kg of mature compost per shift.The soil structured matured compost whichhas a uniform colour and is odour-free, wouldbe utilised for in-house gardening. This willfurther enhance the green cover inside the steelplant.

Greenery Development in Tata SteelWorksTata Steel's Parks and Garden is engaged inenhancing the greenery aspect of the SteelWorks. In FY12, 8,096 nos. of trees wereplanted and about 8656.9 m2 provided witha grass cover. Reclamation of waste land inthe Works area and greening of departmentsis being carried out regularly by WorksGarden.

Rain Water Harvesting (Tata Steel Works-Steelenium Hall)Tata Steel has undertaken rainwater harvestingon an extensive scale at its Steel Works. In thedays to come, this application will help theWorks utilise and conserve water in an eco-friendly way that can be replicated the worldover. Needless to say, Tata Steel may once againbecome a role model to many industries inwater conservation.

Relocation of TreesTata Steel Works Garden Department hasmastered the technique of tree relocation insidethe Steel Works and, till date, they have re-located seven trees of large diameter (Peepal& Banyan) and 42 semi-tree species achievinga survival rate of 85%. Some of the areasinclude CRM, CAPAL, Pellet Plant, etc.

The Quality of Life of the people of Jamshedpur is given paramount importanceby Tata Steel, ably supported by Jamshedpur Utilities and Services Company

(JUSCO). JUSCO's focus on maintaining a balance between green and openareas with land used for human settlements prompted the Company

to vacate large tracts of land used by encroachers as a dump yardor truck or trialing parking lot and turn them into Jogger's havens.

Use of Plastic in Road MakingTo ensure that our city remains a clean and green, it is

important that used plastic - one of the prime toxicwastes being generated every day - be put tostrategic use. JUSCO, being a comprehensive urban

infrastructure service provider, decided to use plasticas an input in road-making. The Company imbibed the

technology of using plastic waste in roads under Dr RVasudevan Thiagarajar College of Engineering, Madurai. On

November 30, 2011, JUSCO successfully constructed approx. 900sq mtrs stretch of road using plastic waste near Income Tax

Commissioner Office in C H Area, Jamshedpur. The success of thisexperiment prompted the Company to explore the possibilities of using

plastic waste in town roads in a big way. Subsequently, two more roadswere constructed in the town to further test the durability. Plastic roads

would be a boon for Jamshedpur's hot and extremely humid climate,where temperatures frequently cross 45°C and torrential rains

create havoc, leaving most of the roads with big potholes.In the near future, we will have strong, durable and eco-friendly roads which will relieve Jamshedpur from all type

of plastic-waste.

Jamshedpur Compost Plant - A first-timer inJharkhand

Tata Steel once more emerged as a pioneer with the successful installationand operation of a Compost Plant at Jamshedpur - the first of its kind inJharkhand. The New Compost Plant is the outcome of Tata Steel's interventionto bring in world class technologies and practices in the areas of urbaninfrastructure sector to continuously upgrade the existing service level standardand look for opportunities for new services for the citizens of Jamshedpur.

Composting process is quite commonly used and results in production of astable product - compost - which, depending upon its quality, can be used asa low-grade manure and soil conditioner. The process results in conservationof natural resources and is an important processing method, especially inagricultural and horticultural areas.

Sustainable development and effective management of environmental impacts have become key goals forpolicy action at global and local levels of all industrial bodies today. It is now widely recognised thatunderstanding sustainability and integrating its principles and methods into everyday practice is vital for the

environmental, economic and social welfare ofsociety.

Against this backdrop, Confederation of IndianIndustry (CII), organised a seminar on ‘SustainableEnvironment Management’ on February 06, 2012,in Jamshedpur. Participants included industries,educational institutes, consultants andGovernment, who came together toreview, assess and appreciate different

and several environmental initiatives undertaken by them and also toencourage industries and institutes to take up more and moreenvironment-related tasks.

CII Jharkhand Council has also been making concerted efforts inthe direction of bringing growth and development in the Stateright from its inception in the year 2000. The Council facilitatedDepartment of Industries, Govt. of Jharkhand in coming upwith an Industrial Policy of Jharkhand in the year 2001. CII iscurrently engaged in designing tools for improving energyefficiency. As a part of this activity workshops are beingorganized all over the country.

Reclamation of Jugsalai Muck Dump

The dump site would be properly graded, leveled and the slopeswould be protected with Geo-net sheets and, with a layer ofthin soil cover, the whole area would be vegetated withgrass, shrubs and trees with wide canopy. Rain waterharvesting (RWH) structures like ponds areconstructed locally to sprinkle water on the topsoil intermittently so as to sustain the vegetationcover. Proper vegetation cover with plan for long-termsustenance will prevent erosion of the top soil and preventexposing the underneath dump material. The top layer of8mm is covered with a mix of good earth, well rotten manureand cocopeat. The plantation is done in a pit of 50 cm depth forshrubs and 75 cm for trees; these pits are again filled with good earth,cocopeat and manure.

CII: Inspiring Humanity to protectour environment

A Green Economy is one of the few alternatives that have the potential to pave the way for asustainable future for generations to come. The alternative today lies in the hands of currentgeneration on whether:(a) to take hard decisions and pave the way for a smoother transition to a better future with the

possibility of reversing climate change or(b) accept the way things are with the risk of an irreversible climate change, thereby leaving

future generations and with limited options to choose from

Leaders globally need to rise above short-term perspectives and immediate gains and embarkon the road to a sustainable future.

Way forward
