Steel is produced by using two types of raw materials: hot metal or pig iron, and steel scrap, and through two types of processes: basic oxygen furnaces (BOF) or basic oxygen steelmaking and electric arc furnaces (EAF). In BOF steelmaking, about 75% of iron comes from the hot metal produced by blast furnace process, the remaining 25% of the raw materials is steel scrap.
