摘要

Life Cycle analysis studies have been undertaken for a range of steel making routes, including conventional and emerging technologies. It has been shown that the new iron and steelmaking technologies based on coal can match greenhouse gas emissions (GGE) from gas based reduction processes when credits for slag use in cement, and for electricity from offgas, are taken into account. There is a range of improvement opportunities that offer the potential for major further Reductions in GGE -a 50/100 reduction is a realistic target over time.
