About

Sublime Systems is leading a swift and massive transition to a clean cement manufacturing future. Sublime’s breakthrough electrochemical process avoids the pollution caused by ordinary portland cement’s use of fossil-fueled kilns and limestone feedstock. Sublime instead extracts reactive calcium and silicates from abundant raw materials at ambient temperature, to make ASTM C1157-compliant Sublime Cement™, a 1:1 replacement for OPC in concrete. Because it does not require carbon capture, Sublime’s technology offers a clear path for cost-competitive clean cement manufacturing at scale.
