Canada: CarbiCrete has obtained the first Environmental Product Declaration (EPD) for its cement-free concrete masonry units (CMUs). The products have specific CO₂ emissions of 11.7kg/m³ for the CMUs, 94% below the industry norm of 200kg/m³. FinancialWire News has reported that CarbiCrete’s recipe for the CMUs replaces cement with steel by-products, while also sequestering CO₂.

Concrete products company Canal Block is set to commence production of CarbiCrete CMUs at its Port Colborne plant in Ontario in early 2025.

Finland: Saint-Gobain and steel company SSAB are building a new slag processing plant in Raahe in North Ostrobothnia. When commissioned in 2025, the plant will convert SSAB’s steel slag into 90% reduced-CO₂ binders to replace cement in building materials. The partners aim to reduce the CO₂ emissions of Finnish building materials production by 200,000t/yr. Saint-Gobain first patent a slag-based binder design in 2022.

Saint-Gobain will invest €12m and SSAB €2m towards the cost of the plant, which will be 35% funded by Sustainable Growth Finland, under the NextGeneration EU initiative.
