Ecocem and Tata Steel IJmuiden in the Netherlands have signed a Memorandum of Understanding (MoU) to advance the use of Basic Oxygen Furnace (BOF) and Electric Arc Furnace (EAF) steel slags as next-generation materials in low-carbon cement as Supplementary Cementitious Material (SCM). The MoU aims to reduce CO₂ emissions from cement by lowering clinker use, advance circularity across steel and cement value chains and expand access to low-carbon concrete solutions across Europe. The MoU builds on an existing joint research program and sets out a shared intention to explore new technical, commercial, and regulatory pathways for the valorisation of these steelmaking slags produced at Tata Steel IJmuiden.
