ZERO WASTE MANAGEMENT AND GREEN STEEL BY REPLACEMENT OF STEEL MILL SCALE IN ECO FRIENDLY CONSTRUCTIONP. Ganeshprabhu and P. Chandrasekaran
In steel Industry, the manufacturing of steel is coupled with the production of solid waste materials like slag, dust, sludge, etc. Momentous quantities of wastes are generated from steelmaking process which is a spotlight point in recent years. Its exploitation as well as environmental impact, Mill scale is one of waste materials which are produced as a result of hot undulating of steel in all steel companies. On the other hand, mill scale is painstaking a rich iron resource with least impurities. This paper recapitulates and scrutinizes the generation, composition, characteristics and present status of the employment of the most of the wastes engendered from the steelmaking processes. The alternate solution for avoiding environmental pollution was studied and the usage of steel mill scale in construction is the levelheaded solution was reviewed in numerous research works. The interaction of steel mill scale within the concrete has been methodically investigated. The partial replacement of steel mill scale was examined to explore the various expansions for full amount recycling of solid waste engendered from steel industry, so that the visualization for making clean and green steel with zero waste can be attained for endurance and enlargement of steel business in future.
