About
alterBiota is a Nova Scotia-based cleantech startup that makes deltaC (βC), a biochar-derived liquid concrete admixture produced via a patented process from forestry-waste biochar. The product stores biogenic carbon in concrete and enables cement reduction, claiming up to 30% embodied-carbon reduction. The company entered commercial production in December 2025 following 2025 field trials with Casey Concrete and CarbonRun.
