Recycling is the method used to reduce the environmental impact of large volumes of materials, the sparing use of resources is another relevant factor here. The waste materials which occur in the foundry and st eel industry alongside the target products most be used elsewhere or returned to the foundry and steelmaking processes. The result will be that the need to dispose of material s will be greatly reduced , so alleviating the demand for landfill capacity. In addition, raw material depo sits will be conserved a...
