Brimstone

Brimstone is a climate technology company that has developed a breakthrough process to produce carbon-neutral and carbon-negative Portland cement. While not a traditional healthcare or pharmaceutical company, Brimstone utilizes industrial biotechnology and chemical engineering principles to replace carbon-intensive limestone with calcium silicate rocks. This process produces the same structural cement used globally but generates magnesium compounds as a byproduct that actively absorb CO2 from the atmosphere. The company is currently scaling its technology to decarbonize one of the world's most carbon-intensive industries.
