Carbon mineralization 10M times faster than nature. $25M raised. World's first CO2-neutral bridge. ## Company Overview Paebbl is a Dutch climate tech company founded to commercialize carbon mineralization — a process that permanently converts captured CO2 into solid carbonate minerals used in construction materials. The company was founded on the scientific insight that natural rock weathering sequesters carbon dioxide over geological timescales, and that this chemistry can be accelerated by 10 million times in an industrial process to produce building materials with a net-negative carbon footprint. Paebbl's core technology converts waste CO2 streams into calcium and magnesium carbonates that can replace conventional aggregates, fillers, and binders in cement and concrete.\n\nThe company's primary product is the world's first commercially viable CO2-derived building material, produced by reacting captured carbon dioxide with alkaline industrial wastes such as steel slag and mine tailings. This dual-use approach both sequesters carbon and upcycles industrial waste, improving the economics of carbon removal compared to storage-only approaches. Paebbl's materials target the construction industry, one of the largest emitters of CO2 globally, and are designed to be drop-in compatible with existing concrete and cement manufacturing workflows.\n\nPaebbl raised $25M to scale its production technology and advance commercial partnerships with construction and industrial companies. The company is headquartered in the Netherlands and operates at the intersection of carbon capture utilization and storage (CCUS), circular materials, and green construction. As demand for verified carbon removal credits and low-carbon building materials accelerates, Paebbl is positioned as a rare company that can monetize carbon removal twice — through the building material itself and through associated carbon credits. ## Frequently Asked Questions ### What does Paebbl do? Converts captured CO2 into carbon-storing building materials through mineralization 10M times faster than nature. ### What milestones has Paebbl achieved? First continuous CO2 mineralization plant (2025) and first CO2-neutral concrete bridge (Jan 2026). ### How is Paebbl funded? $25M venture funding + EUR4M EU Innovation Council grant. ### What is carbon mineralization and how does Paebbl use it? Carbon mineralization is the process of converting CO2 into stable mineral carbonates — essentially turning gaseous CO2 into rock. Paebbl uses this chemistry to permanently store CO2 captured from industrial flue gases by reacting it with magnesium silicate minerals, producing a carbonate that can substitute for cement filler. ### What product does Paebbl sell? Paebbl sells a magnesium carbonate mineral that acts as a cement substitute or concrete filler — replacing a portion of Portland cement (which itself produces CO2 when manufactured) with a material that has permanently stored CO2, resulting in net-negative concrete. ### Who are Paebbl's target customers? Paebbl targets cement manufacturers, concrete producers, and construction companies seeking to reduce the embodied carbon of their products. Industrial emitters (steelmakers, cement plants) are also potential CO2 supply partners. ### How does Paebbl's carbon credit model work? Each tonne of CO2 mineralized by Paebbl and embedded in construction materials constitutes a durable, permanent carbon removal — qualifying for high-quality carbon credits from voluntary market buyers such as Microsoft, Stripe, and Google who have committed to purchasing permanent CDR. ### Where is Paebbl based and what is its funding status? Paebbl is a Norwegian carbon mineralization startup that has raised early-stage venture funding from European climate tech investors. It is scaling from lab to pilot plant with operations targeting industrial CO2 sources in Europe. ## Tags energy, b2b --- *Data from geo.sig.ai Brand Intelligence Database. Updated 2026-04-14.*
