SSAB and Heidelberg Materials are launching a four-year research project focused on transforming electric arc furnace (EAF) slag into a low-carbon Supplementary Cementitious Material (SCM). The project has received funding exceeding SEK 20 million from The Swedish Agency for Economic and Regional Growth, supported by the Just Transition Fund.
This collaboration includes Luleå University of Technology, University of Oulu, and Swerim, aiming to optimize the slag for cement and concrete applications. As SSAB transitions to electric arc furnaces in Oxelösund by 2027, this initiative represents a significant step towards sustainable production methods. Successful implementation could substantially reduce CO₂ emissions in the construction sector, aligning with circular economy principles.
