Building with Carbon, Not Against It

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.
