Paebbl, a Dutch-Nordic carbon capture startup, has secured $25 million in funding to transform CO2 into building materials. The funding round was led by Berlin-based VC Capnamic, with participation from cement industry giants Holcim and Goldbeck. The company plans to use the funds to expand its offices in Helsinki, Stockholm, and Rotterdam, where its pilot plant is located near major carbon emitters like Shell, BP, and ExxonMobil.
Paebbl’s technology accelerates the natural process of carbon mineralization, where minerals react with atmospheric CO2 to form carbonates like limestone. The system feeds captured CO2 and crushed olivine rock into a reactor, converting the CO2 into carbon trioxide and binding it to olivine. This process produces magnesium carbonate powder, which can replace additives in construction materials, effectively turning buildings into carbon sinks.
Paebbl’s carbon capture expansion plans
Co-founded in 2021 by Marta Sjögren, Jane Walerud, Andreas Saari, and Pol Knops, Paebbl is part of a growing cohort of startups focusing on carbon capture, utilization, and storage (CCUS). Paebbl celebrated its first ton of CO2 captured this past June and is developing its first demonstration plant, which is expected to begin operations early next year.
The company aims to increase its production capacity to 3 tons of rock powder daily for use in industry trials. Paebbl plans to establish a commercial-scale plant by 2027 and bring 1 million tons of its product to market by 2030. The startup will generate revenue from selling the rock powder and providing carbon removal credits to companies seeking to offset their emissions.
The new funds and strategic partnerships position Paebbl to contribute to global decarbonization efforts by turning the construction industry into part of the solution.
