News Highlights

This startup CEO claims he can completely decarbonize the cement industry
Brimstone Energy, a California-based startup, is one of several companies trying to reduce the carbon emissions from the production of cement, which accounts for about 8% of global carbon emissions. Brimstone is using a different rock but producing standard, so-called ordinary Portland cement. Brimstone is using a calcium silicate rock that is even more abundant than limestone and uses patented technology to remove the calcium.
Cleantech startup Brimstone’s carbon negative cement lands first industry certification
Brimstone’s green Portland cement received third-party certification that it meets the ASTM C150 standard, one of the most commonly used materials standards in construction, the Washington Post reported. It is the first carbon-neutral or carbon-negative Portland cement to meet the requirement, according to Brimstone. The approval is a key step toward deploying Brimstone’s carbon-negative cement production to the market, and tackling building-related carbon emissions.
