The Electric Arc Furnace (EAF) offers an alternative method of bulk steel manufacture. It makes steel from what would otherwise be unsightly and environmentally damaging scrap metals. It also consumes much less energy than the BOS furnace. Every tonne of EAF steel uses about 7.4 GJ of energy compared with about 16.2 GJ for every tonne of BOS steel.
