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. New ore is still mined in order to supplement production of steel and steel products.
