In a push to decarbonise the economy, Indian Oil Corporation (IOC), the nation's largest oil firm, will recycle 100 million discarded mineral water, cold drink and other PET bottles annually to make eco-friendly uniforms for staff that man its petrol pumps and LPG distributor agencies. The firm also rolled out indoor cooking stoves that can be run on both solar power and auxiliary energy sources to offer households a cheaper and environment-friendly cooking solution.
