• Decarbonization in steel | McKinsey

     · While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material. As the predominant production method in Europe is the conventional, coaldependent BF/BOF process, the need to assess alternative breakthrough technologies to reduce carbon dioxide emissions is high. Indeed, almost all ...
