Sublime Systems offers Sublime Cement®, a whiter, more durable, and cleaner replacement for Portland cement produced via an ambient electrochemical process that eliminates the traditional kiln. The process reduces energy intensity by 30-40%, avoids emissions of CO2 and other pollutants, and up-cycles rock or even toxic industrial waste into cement and pure mineral streams with minimal waste. Backed by major builders and materials companies, Sublime has been deploying the cement in real-world projects since 2023 and is scaling to meet growing demand.
