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.
