we're on a mission to decarbonize cement and accelerate the clean industrial revolution.
taking cement from a climate problem to a soution
Our founders, Cody Finke and Hugo Leandri, met at Caltech, where they began working on solutions to some of the world’s most overlooked environmental problems. The cement industry has long been considered one of the most challenging to decarbonize, with most emissions coming from its main ingredient, limestone.
Cody and Hugo believed that to decarbonize cement, their product would need to be chemically and physically identical to the ordinary portland cement that builders everywhere know and trust. The process would need to be extremely low-carbon and cost-competitive at scale.
The Brimstone team developed a breakthrough decarbonized process that produces the same cement and supplementary cementitious materials used today. These materials have the same quality and performance builders have used for decades, but with a key difference: our process doesn’t contribute to climate change.
Today, we're focused on scaling our solution—and taking cement from climate problem to climate hero.

we leave limestone, and it's emissions, in the ground
Traditional cement uses limestone as it’s core feedstock. Limestone is responsible for 60% of cement’s carbon emissions. We’ve developed a breakthrough process to utilize abundant calcium silicate rocks instead of limestone, dramatically reducing our cement’s carbon footprint from the start.

This initiates the negotiations process to finance Brimstone’s first-of-a-kind decarbonized portland cement plant, which would avoid 120,000 metric tons of CO2/year.
Industrial Demonstrations Program Selects Brimstone for $189M Federal Investment
A third-party lab verified that Brimstone cement meets ASTM C150 standards for portland cement, the type of cement used in virtually all concrete construction today.
The Washington Post spoke with our CEO Cody Finke about Brimstone's ASTM C150 certification, the path to commercialization, and the company's plans for the future.
