<h1>Oil major marks 60 years of coastal refinery; plans 5,044 crore polypropylene unit, efficiency gains, net-zero by 2040</h1> A major Indian oil and gas company celebrated the 60th anniversary of its coastal refinery, highlighting historical capacity growth to 15.5 MMTPA, recent operational efficiency gains (notably a 20-25% reduction in raw water use), and planned capital expenditure including a Rs. 5,044 crore polypropylene unit using on-site propylene feedstock. The announcement emphasizes product portfolio expansion, petrochemical integration, regulatory milestones tied to prior project inaugurations, and corporate sustainability commitments (net-zero Scope 1 and 2 by 2040, EV charging rollout). Legal considerations include environmental compliance, permitting for new units, community and labor impacts, and scrutiny of investment approvals and disclosure obligations.
