About

Sublime Systems is on a mission to have a swift, massive, and enduring impact on global CO2 emissions by decarbonizing cement. Unlike net zero solutions that rely on carbon capture or credits, Sublime's fully electrified, "true zero” approach avoids the industry’s legacy fossil-fueled kilns and limestone feedstock, which releases half its weight as CO2. Sublime’s electrochemical process instead extracts calcium and silicates from an abundance of raw materials at ambient temperature, to make ASTM C1157-compliant Sublime Cement™ as a drop-in replacement for ordinary portland cement in concrete.
