A new process could offer a solution to reducing carbon emissions in iron and steelmaking.
BioIron™ uses raw biomass and microwave energy instead of coal to convert Pilbara iron ore to iron and has the potential to support low carbon dioxide (CO2) steelmaking. Modelling shows that when combined with renewable energy and carbon-circulation by fast-growing biomass, BioIron™ has the potential to reduce CO2 emissions by up to 95% compared with the current blast furnace method.
