The waste gases produced by iron and steel production are made up of the same molecular building blocks – carbon and hydrogen – that are utilised to make the wide range of chemical goods that modern civilization requires. The majority of waste gases are now burned, resulting in CO2 emissions.
They are constructing the world’s first large-scale plant to capture waste gas and biologically convert it into bio-ethanol, which has a CO2 reduction of up to 87 percent when compared to fossil transport fuels, and can be used to help decarbonize the transportation sector as a bridge fuel between full electrification and full decarbonization.
