A slew of energy management initiatives have been adopted at the unit level to reduce energy consumption and improve energy efficiency. These include modernization of equipment for future expansion (which may also include incurring a higher capital expenditure) and improving and optimizing the performance of existing equipment and machinery. Some initiatives to use renewable sources of energy such as solar power have also taken off at Angul, Raipur and Raigarh.

We have succeeded in maintaining our India units at zero discharge levels by reusing and recycling of water for a number of purposes like scrubbing of flue gases from blast furnace, use of blow down water for slag granulation, reuse in rolling mill (after oil is skimmed out), installation of close-circuit effluent-recycling system in DRI plant, slag cooling and dust suppression, and reuse of sewage water (after treatment) for horticulture. Rainwater harvesting structures have also been constructed for ground water recharge in consultation with the water resource department across all units. Also, the surplus rainwater collected in the open pits is used to make up water during operations of the unit.
For details regarding energy efficiency initiatives please refer to the Annual Report and Sustainability Report.
