Fact sheet Energy use in the steel industry

Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. Variations and combinations of production routes also exist. The BF-BOF route produces steel using raw materials such as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF-BOF route.
