Brimstone has developed an industrial process for producing industry-standard Portland cement with significantly less carbon emissions. Brimstone’s decarbonized process is a breakthrough in cement production, making industry-standard Portland cement with carbon-free calcium silicate rock instead of limestone. Brimstone cement is chemically and physically identical to conventional Portland cement, with the same quality and performance. Portland cement contains two core products: Portland cement clinker and supplementary cementitious materials (SCM). Brimstone’s revolutionary technology produces clinker and SCM identical in all elements to ordinary Portland cement, except through a carbon-neutral process and without burning coal. Brimstone makes cement from carbon-free calcium silicate rocks, eliminating the release of CO2 in the air. In addition to the calcium, silicon, iron, and aluminum used to make cement, Brimstone rock contains magnesium compound sequesters carbon from the atmosphere, thereby permanently removing CO2.
