According to Clean Tehnica, the study conducted by CRU Group found that electric arc furnaces (EAF) have some 75% lower Scope 1 and Scope 2 emissions compared to blast furnaces when it comes to crude and hot-rolled steelmaking processes.

Mark Millett, chairman at SMA and co-founder, chairman and CEO at Steel Dynamics, said that "sustainability has become one of the most important issues in business today, and the steelmaking industry has long faced the challenge of being incorrectly perceived as one that relies on antiquated, inefficient, and highly polluting processes."

"This new study, which has been long overdue, raises the bar for the way we validate our progress in this area. EAF steel offers the greenest, safest, and most energy-efficient method of steelmaking, and our latest study makes our argument and evidence for this significantly stronger and clearer", he added.

Steel produced by blast furnace, which accounts for 70% of the global steel manufacturing, is being produced at large steel facilities that are melting raw materials into iron and then processing it into steel by burning coal.

EAF steel represents some 70% of the total steelmaking in the US and it is being produced by using electricity and it uses recycled scrapped metals to make the actual steel, releasing less emissions and being an overall less energy-intensive process.

Steelmaking using EAF will have an even lower impact on the environment, as energy companies will implement more clean, renewable sources.
