FACT SHEET Energy use in the steel industry

ENERGY USE IN THE STEEL INDUSTRY Most steel products remain in use for decades or even centuries before their function is no longer needed and they can then be reused, remanufactured or recycled. Therefore, there is not enough recycled steel to meet growing demand. Demand is met through a combined use of the BF-BOF and EAF production routes.
