SSAB, Heidelberg Materials to Advance Green Binding Agent From EAF Slag
04/20/2026 - SSAB announced it has partnered with Heidelberg Materials to develop electric arc furnace (EAF) slag into supplementary cementitious material (SCM), a more sustainable alternative binder in cement.
“Our ambition is to develop applications for the slag that will be generated in electric arc furnaces in the near future. Through this project, we are seizing these opportunities by combining strong expertise and long experience with a shared determination to drive change,” said Marko Mäkikyrö, director of byproduct sales and development at SSAB.
The companies said the purpose of the four-year project is to create methods which optimize the EAF slag into a circular, low-carbon SCM. It will bring together expertise from Luleå University of Technology, the University of Oulu, Swerim, SSAB and Heidelberg Materials.
“We see a good opportunity in including EAF slag from SSAB as part of our strategy to reduce the carbon footprint of our products. Through this collaboration, we unite leading expertise from industry and research with a common ambition to deliver the building materials of the future,” said Magnus Ohlsson, chief executive officer at Heidelberg Materials Cement Sverige AB.
The companies said the research project was given SEK 20 million from The Swedish Agency for Economic and Regional Growth from the Just Transition Fund, along with national financing.
