Sweden/India: Cemvision has received a grant from the Swedish Energy Agency to conduct a joint feasibility study with Tata Steel to convert basic oxygen furnace (BOF) and electric arc furnace (EAF) slags into feedstock for near-zero-CO₂ cement. The 10-12-month study will assess the technical and economic viability of a scalable slag valorisation model, ahead of a planned demonstration facility at Tata Steel’s site.
Cemvision CEO Oscar Hållén said “Being able to, at scale, turn environmental liabilities into valuable resources is exactly the kind of climate innovation heavy industry needs. In partnership with Tata Steel, we hope to show how steel slag can become a cornerstone in near-zero CO₂ cement, while metals are recovered and returned to steel production.”
The project is part of the India-Sweden Industry Transition Partnership (ITP), announced during Cop30 in Belém, Brazil. Tata Steel also received a grant from India’s Department of Science and Technology, with additional partners including IIT ISM Dhanbad and JK Cement.
