Scrap is the cornerstone of green steelmaking. ironmaking is emission-intensive, so the first logical step to reduce emissions is to reuse available scrap. But scrap cannot meet all metallics requirements – stock is limited, collection infrastructure is fragmented, and scrap quality can restrict recycled steel's use.Web

An additional benefit of DRI steelmaking is that the main reaction runs at a lower temperature and therefore requires less energy. The reduction of iron ore takes place in a shaft furnace at a relatively low temperature of about 1,000°C. The reduced iron is then further processed into liquid hot metal in an electric furnace.Web
