Paebbl's Rotterdam Plant Turns CO₂ into Building Materials at Record Speed

Paebbl has launched the world's largest demo plant for continuous CO₂ mineralisation in Rotterdam. The facility speeds up a natural process that locks carbon dioxide into rock. It also produces a silicon-rich powder that could replace traditional building materials like lime. The company completed the plant in record time with support from engineering firms Spie and Vicoma. Funding came from a $25 million investment round led by Amazon, Holcim, and Goldbeck, bringing Paebbl's total raised to $38 million. The Netherlands Enterprise Agency (RVO) also contributed an undisclosed sum.

For every ton of CO₂ captured, the plant generates around three tons of magnesium carbonate powder. Paebbl plans to sell this material as a substitute for lime in products such as wall filler. The goal is to turn buildings into carbon sinks by embedding captured CO₂ in construction materials. No other commercially scaled CO₂ mineralisation plants were operational worldwide by the end of 2024. Paebbl aims to change this by building a full-scale commercial plant in 2027. By 2030, the company wants to bring 1 million tons of its product to market. Revenue will come from selling the rock powder and offering carbon removal credits.

The Rotterdam plant marks a step forward in turning CO₂ into usable materials. If successful, Paebbl's technology could reduce emissions in construction while creating a new source of income. The company's next target is scaling up production within the next three years.
