The manufacture of steel involves steps that are potentially hazardous if not executed with due care and attention. The Group’s businesses are subject to numerous laws, regulations and contractual commitments relating to health, safety and the environment in the countries in which it operates. Appropriate measures for environment protection are taken by adopting BAT (Best Available Technology) and designing pollution control infrastructure to achieve discharge and emissions within statutory limits. Sustainability issues related to Environment impacts at Jamshedpur and social impacts at all twelve locations were prioritised based on a systematic materiality process.

Tata Steel's efforts at continual improvement of its plants and processes are well recognised. Its processes at the Main Works at Jamshedpur comply with the ISO-14001 standard.

A few environment initiatives at plants:

  • To meet environmental standards, dust and other emission levels are monitored for prompt corrective actions to ensure they stay within permissible limits. On initiating the Brownfield steel expansion project to raise production capacity at the Jamshedpur Steel Works, the Company has made large capital investments in Air Pollution Control Equipment (APCE) for new and existing plants.
  • A significant investment has been made to ensure Ambient Air Quality monitoring, Effluent treatment, BOTP and Rainwater harvesting at Mines and Steel works.
  • A new 8 MGD (2 x 4 MGD) Effluent Treatment Plant is being set up at Jamshedpur Steel Works. It will significantly reduce the water consumption of the Steel Works by converting effluents into service quality water for use in cooling and quenching.
  • Increased use of fly-ash bricks instead of fire-clay bricks has enhanced recyclability at stockyards.
  • Bio-Diversity assessment and management processes have been introduced at mines with International Union for Conservation of Nature (IUCN).
  • Transparent Fibre-Reinforced Plastic (FRP) sheets are used at the plants to maximize daylight usage.
  • LD slag is being used as fluxing agent in cement industry, saving CO2, resources and wastes.
  • Coke Dry Quenching (CDQ) is used to enhance waste heat recovery, improve coke quality and reduce dust emissions.
  • More than 94 per cent of the Blast Furnace Slag at Tata Steel is Granulated Blast Furnace Slag. It is used as a clinker substitute in slag cement, saving mineral resources.
  • No hazardous waste is imported or exported by Tata Steel India. The objective remains reduction of hazardous waste generation wherever possible from the perspective of operational efficiency.
  • As part of its commitment to producing energy efficient products Tata Steel invests its best efforts to mitigate GHG emissions through the supply of energy-efficient steel and by-products as well as the solutions proposed for construction material. Tata Steel has achieved a 40 per cent reduction in specific energy consumption in the last 30 years.
  • Collaborations have been made with UNGC, CDP, CEO Water mandate, TERI, CII-GBC and MAIT. The Company is also a WSA Climate Action member.
