The online resource for steel. The steel plant is a lean, green, recycling machine -- making new steel from recycled steel scrap. Enough iron and steel is recycled each year to save the nation 74% of the energy that would be needed to make new steel. Making Steel. How Steel Is Made. To produce steel, facilities use one of two processes: the basic oxygen furnace (BOF) or the electric arc furnace (EAF). The BOF process uses 25-35 percent old steel (scrap) to make new steel. BOFs make up approximately 40 percent of todayâs steelmaking in the U.S. The EAF process uses virtually 100 percent old steel to make new steel. EAFs make up about 60 percent of todayâs steelmaking in the U.S. Our Coke has no caffeine. But you may feel a caffeine jolt if you know how ours is made.
