Process emissions are created when carbon is used to remove oxygen from iron ore, reducing it to pig iron, the key feedstock in the steel industry. Electric arc furnaces (EAFs) can utilize recycled steel scrap, foregoing many of the process emissions associated with smelting new steel from reduced iron ore. EAFs can rely on renewable sources of ...
