Researchers from the University of Birmingham have developed an innovative method for existing furnaces that could reduce steelmakings CO2 emission by nearly 90%. The iron and steel industry is a major cause of greenhouse gasses, accounting for 9% of global emissions. Thats because of the inherent carbon-intensive nature of steel production in blast furnaces, which currently represent the most-widely used practice. In blast furnace steel manufacturing, coke (a type of coal) is used to produce metallic iron from ore obtained from mining which releases large quantities of carbon dioxide in the process. According to Dr Harriet Kildahl, who co-devised…
