Recycling and Reuse Potential of Solid Wastes Produced in Iron and Steel Industry
AbstractIron and steel is one of the important tools for the economy of countries. Iron and steel industry uses energy and high quantity of raw material. Iron and steel production has a number of impacts on the environment, including air emissions, wastewater contaminants, hazardous wastes, and solid wastes. Sources of solid wastes for steel industries may be identified as coke oven by product plant, sinter plant, refractory materials plant, blast furnace, basic oxygen furnace, steel melting shop and rolling mill.In steel industry, solid waste management is aimed to provide maximum benefits from waste products and to generate the minimum amount of waste. To achieve this goal “4Rs” i.e. reduce, reuse, recycle and restoring the materials are being considered as strategies of solid waste management.For minimizing the sources of solid wastes and maximizing the recycle of collected wastes can be opted in the following ways: Identification of sources, quantities and types of solid wastes generated from different sub-processes of steel manufacturing process.To find out the reasons of generation of solid wastes. To use advanced technology for minimizing waste.In efforts to prevent environmental pollution, the priority is to evaluate waste materials for recycle and reuse. Thus waste and damage to the environment are minimized and also provides economic benefits.
