Carbon-negative cement -- Brimstone
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).
