Pig iron is the raw material for all iron and steel products. This is obtained from chemical reduction of iron ore in a blast furnace by a process called as smelting. The main raw materials required for pig iron are: Iron ore: carbonates, hydrates or oxides of iron; Coking coal: high quality coking coals; Flux, limestone or dolomite.

the blast furnace/basic oxygen furnace route (based on iron ore and steel scrap) and the electric arc furnace route (mainly based on steel scrap). Downstream processing into manufactured products and their use has not been included in the inventory. The steel products have also been modelled including the end-of-life process Executive summary
