SRB's foray into steel recycling has given it a leadership pedestal in India on sustainability. As per the National Steel Policy, India's steel production capacity is likely to reach 300 MnTPA by 2030. About 35-40 percent of this capacity is expected to come from the EAF/IF route where scrap is the primary raw material.
