One order of steel; hold the greenhouse gases | MIT News
May 08, 2013· One order of steel; hold the greenhouse gases. The prevailing process makes steel from iron ore — which is mostly iron oxide — by heating it with carbon; the process forms carbon dioxide as a byproduct. Production of a ton of steel generates almost two tons of CO2 emissions, according to steel industry figures, accounting for as much as 5 percent of the world's total greenhousegas emissions.
