We started Bloomineral because we believe materials themselves can be part of the climate solution. Construction doesn’t have to be an emitter; it can become a carbon sink.

At Bloomineral, we turn CO₂ into a resource through large-scale biomineralization. By cultivating specialized, mineral-precipitating algae, we produce ultra-pure, carbon-negative calcium carbonate — a drop-in replacement for mined limestone that locks away CO₂ in solid mineral form for thousands of years.

Our work begins in the LSCE labs, grounded in real benches and pilot reactors, guided by peer-reviewed science and driven by the urgency of our planetary moment. We are pioneering carbon-neutral white cement and forging the path for construction materials that don’t just emit less, but store carbon.

We aim to redefine how materials are made: turning carbon from a waste into a resource, and industry into an ally of the planet’s chemistry.
