Canada: Climate tech startup CURA is collaborating with Aecon Group to test, validate and pilot its low-carbon cement, which it claims can reduce emissions from production by as much as 85% compared to ordinary Portland cement. The electrochemical process removes CO₂ from limestone before kiln use. The company says that the cement is produced at cost parity or below the price of conventional cement with lower emissions.
CURA expects to produce 1.6t/yr of the product at its University of Calgary laboratory by the end of March 2026 and to scale the pilot to 100t/yr by the end of 2026. Aecon will conduct material validation and concrete failure testing and build a prototype, followed by a flagship project in 2027-2028. CURA is raising US$8m in seed rounds to fund the pilot and a 30,000t/yr demonstration plant targeted for 2028.
