Reusable raw materials, such as steel scraps from the body press process, are an abundant by-product of car manufacturing (Fig. 5.10). An electric furnace 6 melts the scrap with carbon (to raise carbon concentration) and ferro-alloys. The chemical composition must be checked before pouring. In the recovery and treatment of byproducts from the coke ovens, sulfuric acid is used for the production of ammonium sulfate and for washing light oils. The consumption of sulfuric acid by the steel industry in 1943 is estimated at 1,580,000 tons, of which something of the order of 280,000 tons were probably used at the coke ovens.
