Minimization of Waste Generation in Steel Sectors

The operation in the integrated steel plant can be classified into three different groups. The first group involves iron making process comprising sintering and agglomeration, coke making and blast furnace operations. Steelmaking which includes all operations from primary steelmaking through secondary steelmaking to ingot/continuous casting constitutes the second group. Rolling and finishing processes including pickling, coating, shearing and other finishing operations constitute the third group . At all these stages enormous amounts of wastes are generated. These wastes have a wide ranging impact on the environment. Thus, minimization of waste through integrated waste management has gained special significance in the present scenario. This paper suerunarizes the scope to reduce waste generation of all kinds in the steel sector. It has been concluded that through the introduction of latest processing technologies, waste can be drastically reduced and whatever generated can be recycled in the process stream or converted into value added products
