Every year 20 million tonnes of steel waste is generated from different steel plants in the country. By 2030, it will be 45 million tonnes every year. The situation is such that mountains of steel waste have formed outside the steel plants. But now this waste is being used. A road has been made in Gujarat from the waste of a plant in Surat. NITI Aayog member VK Saraswat inspected this road today. A report by NDTV's Mukesh Singh Sengar from Surat.
