Waste Disposal and Recycling in Steel Industry

The steel industry in North America has been recycling steel scrap for more than 150 years. The steel industry needs scrap to produce new steel, which ensures that all steel products contain anywhere from 25 percent up to 100 percent recycled content. It also is cheaper to recycle steel than it is to mine ore to manufacture new steel.

Mill scale

Mill scale is formed on the outer surface of plates, rolls, sheets or profiles when iron and steel are heated for rolling, forging, or other processing. Being produced during the reheating, conditioning and hot rolling operation, mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
