Tata Steel has always believed in adopting an innovative approach in its processes and product development to ensure the best use of available technology in its operations. Energy conservation and efficiency improvement measures are continuously developed and implemented at Tata Steel's plants in an effort to meet environmental challenges effectively.

 

Tata Steel India

The Company's efforts at continual improvement of its environment are well recognised. Tata Steel Main Works at Jamshedpur has been re-certified to ISO-14001 standard. In addition Noamundi and Joda East Iron Mines, Sukinda Chromite Mines, Jamshedpur Town Division, Ferro Alloys Plant, Tubes Division, Bearings Division and West Bokaro and Jharia Collieries have also been re-certified for compliance to the requirement of international standard ISO-14001, 1996.

Tata Steel is fully aware of the impact of its activities, products and services on the environment at a local and global scale. That is why the Company's endeavour is not limited to compliance with applicable legislations, but to go beyond compliance with minimisation of process waste, optimisation of recovery and recycling of waste materials.

In Tata Steel plants in India, a few initiatives taken in recent times are:

  • Conversion of coal-fired boiler no. 7 & 8 at Power-house-3 to by-product gas firing. All the four boilers at this power-house now have by-product gas firing.
  • Installation of Variable Frequency Drives at LD Shop and Hot Strip Mills.
  • Measures for reducing electrical power consumption.

Initiatives that are in the implementation stage include:

  • Installation of Top recovery turbine at ‘G' & ‘H' Blast Furnace.
  • Recovery of sensible heat of coke by installation of Coke Dry Quenching system in Batteries 5, 6 & 7 at Coke Plant.
  • Enhancement of waste heat recovery at Sinter Plants.
  • BF Gas fired re-heating furnace at Hot Strip Mill.
  • Improvement in LD Gas recovery.

These initiatives have led to a number of positive results in energy efficiency.(2007-2008)

  • Lowest ever Plant Specific Energy Consumption of 6.655 Gcal/tcs.
  • Lowest ever boiler coal consumption of 38.97 kg/tss.
  • Higher LD Gas Recovery of 66.80 Nm3/tcs.
  • Higher combine boiler efficiency of 83.67%.

Tata Steel Europe

Energy optimisation is an important element of TSE's emission reduction strategy. Initiatives for the same are in place at the Company's integrated sites and at other locations. The Energy Efficiency Task Team works with the Divisions to identify and facilitate energy optimisation schemes across all sites.

A few examples of initiatives taken are:

  • Strip Products, IJmuiden, launched its YmGreen programme to achieve CO2 emissions reductions from in and around the site that resulted in energy efficiency by 20%.
  • Special Strip, Trier, has assessed routes to optimise waste heat from the process and analysed the heat loss from the manufacturing unit itself.
  • At Engineering Steels Division, Rotherham, the commissioning of a new small bloom continuous caster has achieved a 28% reduction in direct and indirect CO2 emissions per tonne since 2005.
  • At Hayange, we have invested in new automation and optimisation computer systems to improve control on the reheating furnaces and reduce our energy consumption by 11%.
  • Teesside Cast Products has been working with Carbon Trust to audit the energy efficiency of its operations as part of a regional project with OneNorth East.

NatSteel Holdings

NSH processes comply with ISO standards and regulations, ensuring that the Company is able to address adverse environmental impacts. One area that is continuously monitored is the fume extraction system for the protection of employees and the environment. NSH also continuously explores the effective use of energy, raw materials, water and effective management of waste generation, zero soil fill and slag. Adhering to the Tata Steel Group philosophy, NSH continues to subscribe to its philosophy of giving back to society.
