Abstract
Solid waste generation is a major concern in all integrated steel plants. The production of steel is highly associated with the generation of these wastes, such as slags, dust, sludges, mill scales, muck and debris. These wastes can be reused or dumped otherwise could be hazardous to the environment and mankind. Approximately about 500 kg of solid waste is generated for every tonne of steel in the steel industry. Although the sustainability of Indian steel industry mainly depends on the management of these wastes. The only concern is to utilize the maximum waste to avoid waste disposal issues. The concept of zero waste management and green steel making are nowadays important terms which could support the making of steel with low CO2 emissions. The solid wastes are being consumed within the steel plants as raw material and have also been used as landfills. Solid wastes also provide a huge scope for revenue generation by extraction of valuables from them. This paper summarizes the actual waste management data of various solid wastes generated in terms of volumes by the major Indian steel plants and their utilization at present by these steel plants have been included and discussed.
