The Cement Startup That Stopped Trying to Replace Concrete - and Learned to Sneak Algae Into the Mix
Prometheus Materials spent years teaching microbes to make stone. Its more consequential trick was learning that the concrete industry did not want a revolution - it wanted a familiar bag of powder that could survive the batch plant.
BioSqueeze Inc.
BioSqueeze Inc. is a Butte, Montana company and the self-described world leader in commercial biomineralization. Its core technology pumps low-viscosity, self-diverting fluids carrying naturally occurring soil bacteria into oil and gas wells, where the microbes precipitate crystalline calcium carbonate (limestone) to permanently seal leakage pathways as small as one micron. The result is a gas-tight barrier that eliminates sustained casing pressure and stops fugitive methane emissions, helping operators meet well-integrity and environmental obligations across producing, plugged, and storage wells.
