About Paebbl Paebbl is an industrial resilience company turning captured CO₂ into carbon-storing building materials. We accelerate the natural process of CO₂ mineralisation- in which CO₂ reacts with minerals to form stable carbonates from thousands of years -to a matter of hours, producing a carbon-negative powder that can replace conventional, heavily emitting cementitious materials. Having switched on the world's first continuous CO₂ mineralisation demonstration plant, we are now scaling from startup execution into structured industrial operations. It is a fast-moving environment where pragmatism, ownership, and the ability to build things that work in the real world matter.
