Tata Steel understands that Steel is one of the central pillars of a green economy, in which economic growth and environmental responsibility are mutually dependent.
Recycling is especially important in a green economy because it conserves valuable resources. Steel in itself is 100% recyclable. Once produced, its life-cycle is potentially endless. A patron of environment sustainability and conservation, Tata Steel ensures its products and processes are environment friendly. The Company offers innovative product solutions using carbon efficient technologies and processes that are in line with the Company's vision of making the planet greener. Towards this vision, Tata Steel continuously supports its customers in proper usage and disposal of finished goods.
Few of the recent initiatives by Tata Steel in this direction include:
Galvano: Tata Steel’s zero spangled galvanized products (Galvano) are coated in a lead-free coating which is eco-friendly. Trivalent Chrome passivation is also offered as per the customer’s requirements.
Nest-in housing solution: The Nest-in housing solution by Tata Steel is made of cold rolled high strength steel sections and is an excellent building solution which does not pollute the environment like cement & brick in the conventional RCC. It does not require any welding, cranes or usage of water, therefore making the construction pollution free and environment friendly.
The Nest-In Bio-toilet: This is an integrated solution, commercialised in FY 13, made up of a Bio-toilet system and Nest-In super structure. The bio-toilet system is developed under license from DRDO. The Bio digester disposes human waste in 100% eco-friendly manner and generates colourless, odourless water and inflammable gas.
ReadyBuild Cut & Bend rebar (CAB) products: To its retail consumers, the Company offers ready to use Cut-And-Bend rebars to eliminate difficult and labour intensive task at site. This initiative helps in reducing GHG emission due to reduction in scrap.
Fe600: Marketing of 40mm Rebar, Fe600 rebar has resulted in reduction in specific steel usage compared to 32mm rebar & Fe415 / 500 grades of rebar. This also leads to a reduction in GHG emission.
Fe500/Fe550D: The consumption of Fe 500 is 15% lower than Fe 415 rebar, resulting in reduction of overall steel consumption in the infrastructure sector. This effectively reduces GHG emission and conserves natural resources.
Super Ductile Rebars: Super ductile - earthquake resistant rebars ensure safety even during a major earthquake. New Corrosion Resistant Steel (CRS) rebar developed by the Company have higher corrosion resistance quality.
LCWR: Tata Steel’s superior quality Low Carbon Wire Rods have helped customers to shift from the “Acid Pickling" process before wire drawing to only "Mechanical De-scaling". By using this improved product, customers are able to save approximately Rs.800/ t.
High Strength C-Mn 440 Steel: Development of this product has helped in light-weighting of cars, leading to low carbon usage in lifetime of vehicle and also increasing the fuel efficiency to a great extent. This also helps in localisation of the grade for the Automotive OEMs.
VAVE (Value Analysis / Value Engineering) Programme: Based on its expertise on automotive steels, Tata Steel (R&D, Technology Group, Operation Managers and Sales Manager) works with Customer teams to generate ideas on steel usage in a vehicle with an aim to reduce cost and weight of the vehicle. These ideas not only reduce cost but also reduce GHG emissions through the life cycle of the vehicle.
Replacing wood as packaging materials: Tata Steel has completely replaced wood by recyclable and reusable EPS saddles for stuffing export containers. This is the first time an Indian Steel maker has used recyclable material for stuffing containers. This move has resulted in savings of 50 m (linea) of timber per container. It has also increased the efficiency by increasing the container floor area, allowing for a significant savings in freight costs.
In addition to the above initiatives, Tata Steel has also installed a Rain Water Harvesting System (RWHS) with zero discharge facility at the Faridabad stockyard. Similar system is also being planned at Chennai, Kanpur and Ludhiana stockyards. At the same time, by using transparent sheet in the roof, Faridabad stockyard has reduced the electricity consumption by 80%. Similar plans are also there for Chennai and Kanpur stockyards. Also, Tata Steel has used Fly Ash Bricks instead of fire clay bricks for new constructions at the stockyards as the former are environment friendly.
