Abstract
'Wealth from Waste' is a known phenomenon for integrated steel plants of the world. For the sake economic sustainability, the thumb rule of 'reduce, reuse, recycle and restore' appears to be most suitable for the various steel industries (Sarkar and Muzumder, 2015). For this purpose, while making value addition in the process of steel making various mitigation measures are adopted to control the pollution of air, water, soil, etc. The processing of raw materials in integrated steel mill plants is brought about with the help of processes such as direct reduction, blasting furnace, electric arc furnace (steel melt shop), mill sintering, coking oven & palletisation, etc. The by-products of integrated steel mill are coke fines, coal-fines, mill-scale, sinter-fines, SMS slag, BF Slag, coal tar, sulphur, granules & GCP dust. During sustainable waste management, these are reutilised to enhance production quality. The smart use of energy and water consumption also is an added responsibility. The entire waste utilization within the plant demands proper disposal and environmental safety.
The present study it is observed that integrated steel plant waste Generation, Utilisation & Restore for Utilisation from Year 2014 to 2022 the utilisation of solid waste was almost 85% & Remaining 15% was stored for further use for improved plant performance and Sustainable of waste Management.
