About
Exterra Technologies (formerly Exterra Carbon Solutions, rebranded February 2026) is a Montréal-based cleantech company that processes legacy asbestos mine tailings into critical minerals (magnesium oxide, nickel concentrate, amorphous silica) via its proprietary LOW™ process, and can optionally mineralize CO2 into stable carbonates via its ROC™ process. The company closed a CAD $20M Series A in May 2025 (co-led by Clean Energy Ventures and BDC Capital) bringing total funding to CAD $32M, and plans Hub I commercial construction in 2027. It has a Frontier pre-purchase agreement and partnerships with BASF, Énergir, and Deep Sky for carbon storage.
