Paebbl, the company transforming CO2 into valuable construction materials, has completed the next phase of its record-breaking scale up of operations, successfully starting up their Demo plant - which has been in operation since late March. The project was delivered in 18 months from start to finish.

This milestone represents a world-first for continuous CO2 mineralization at demo scale, laying the groundwork for scaling up the production of future-proof building materials for a more resilient supply chain of essential materials. Paebbl completed its first 24 h continuous production run with the plant on March 26th. Meeting this milestone is a breakthrough step for scaling up a critical technology for a clean industrial base.
Completed not only at record pace but within budget, the project was executed together with engineering companies Spie and Vicoma, with financial support from the Netherlands Enterprise Agency (RVO).
“Reaching this milestone in record time shows how deeply our team and partners believe in the urgency and promise of building with CO2 as an input. With this plant, we’re one step closer to high-performance materials and climate impact going hand in hand - on a scale that really matters,” said Andreas Saari, Co-CEO and Co-Founder of Paebbl.
Paebbl’s achievement in going from project start to a fully commissioned plant in just 18 months showcases how rapidly the company can move, far outpacing typical project timelines in the sector.
The Demo plant uses olivine to permanently lock away CO2, transforming it into supplementary cementitious materials (SCMs). Traditionally these technologies have been limited to batch processes or laboratory scale due to complexities in maintaining high temperatures, pressures, and chemical reactions over extended periods. By showcasing continuous, 24/7 operation at a demo-scale facility, Paebbl proves that its technology is not only technically sound but scalable to meet the rigorous demands of global construction supply chains.
As cement accounts for more than 8% of global emissions, the construction sector is under increasing pressure to reduce its carbon footprint while maintaining the strength, durability, and reliability demanded of critical infrastructure.
Paebbl’s approach turns CO2 into a valuable building material rather than letting it go to waste, enabling a new class of future-proof materials that can be produced close to end markets with lower energy inputs than conventional cement. Beyond the environmental benefits, this paradigm also bolsters the resilience of supply chains, helping the industry cope with fluctuating raw material availability, costs and regulatory pressures.
“The completion of stage one of our Demo plant is a testament to Paebbl’s determination to make carbon-storing materials a practical reality. By swiftly integrating and commissioning our core equipment, we’re now well-positioned to ramp up production and gather the data we need to move forward to full commercial scale,” adds Arnold Choi, Vice President of Engineering & Deployment at Paebbl.
