Paebbl logs 2,500+ plant hours as it moves its rapid CO₂-mineralising tech toward industrial-scale deployment.

Carbon can take centuries to turn into stone in nature, but a Netherlands-based carbon-mineralization startup says it can now do the same in hours, and at a scale that looks increasingly industrial. Paebbl has hit several engineering milestones that signal a shift from R&D into manufacturing readiness.

The company claims its technology, which locks CO₂ into rock-like materials, is already being used in “real-life projects” and now sits on the cusp of commercial deployment.In the last quarter, the startup’s R&D centre crossed three operational benchmarks, including 500 hours of continuous operation at its Demo plant, more than 2,000 hours at its Pilot plant, and a transition from isolated testing to continuous-operation “sprints.”These metrics are uncommon in the early life of any deep-tech climate process and indicate a rapid scale-up path.Paebbl says these achievements arrive at a moment when construction firms are aggressively rethinking their material choices in the race toward decarbonization.Learning at scaleAccording to the team, reaching 500 hours on the Demo plant — commissioned earlier this year — represents a foundational step toward industrial-scale mineralization.The Demo plant is equipped with full-stack sensor coverage designed to harvest data from every run. “Each run, whether successful or challenging, generates data that compresses our development timeline,” the company said.Engineers can track the plant remotely using time-series data synced from reactors and lab equipment to the cloud. “When something doesn’t behave as expected, we know immediately rather than discovering it hours later,” Paebbl noted.The company has also built an internal AI knowledge system that employees can query to access operational details. This “seamless knowledge flow,” as Paebbl describes it, removes friction and helps the team iterate faster.Digital twins everywherePaebbl says its operations rely heavily on simulation. “We can run one million parallel simulations, but we only have one world,” the team said.These simulations are used to create digital twins of reactors, production lines, and eventually the entire value chain, a move that aims to reduce capital expenditure while speeding up material development.The Pilot plant, which has now surpassed 2,000 hours, continues to deliver consistent output to customers while the company focuses on optimizing its cost base. Together, the Demo and Pilot plants form the testbed for what Paebbl calls its “technology-first approach,” combining human operators, data systems, and rapid deployment cycles.The next phase is more ambitious: designing its first commercial-scale facility, or FOAK plant, which will unlock significantly larger production volumes. Paebbl says surging demand from construction players, who are seeking lower-carbon, feedstock-flexible materials, is driving this step.The company emphasises that the challenges seen so far are “expected parts of de-risking a novel process.” With each operational hour, Paebbl claims it is improving reliability, output quality, and system efficiency.Looking ahead, Paebbl says the real milestone is not just the hours logged, but “the rate at which we’re learning and able to improve based on data.”The team expects to announce additional milestones as it moves closer to commercial rollout.
