RECYCLING AND UTILIZATION OF SOLID WASTE GENERATED IN THE ROURKELA STEEL PLANT, ODISHA
Now-a-days developing countries compete with each other in primarily metal production. India occupies the 2nd position in metal production after China in the world. So this creates its own challenges in terms of management of solid waste produced from metal manufacturing industry. Amongst the metal manufacturing industries, Steel industries contribute largest amount of solid wastes. In India there is very rich deposits of hematite and contains higher percentage of alumina and inferior cokes. Steel plant produces a variety of solid waste material viz. BF slag (Air cooled & granulated), SMS slag. BF GCP sludge, sinter sludge, coke breeze and fly ash etc. The granulated BF slag is used for cement production but the slag containing high amounts of Fe is a major challenge to human being. This paper discusses the issues pertaining to the solid waste generation in Rourkela Steel Plant, Odisha in terms of volumes toxicity, challenges and efforts towards recycling and utilization in eco-friendly manner.
