Decarbonizing cement—without changing the product or price


Brimstone is on a mission to decarbonize the cement industry, which today is responsible for 7.5% of carbon emissions annually.

Founded in 2019, Brimstone developed a breakthrough carbon-negative process to produce the same ordinary portland cement and supplementary cementitious materials used today. These materials have the same quality and performance builders have trusted for decades — now with a positive climate impact.
