Paebbl

Paebbl, a carbon storage company, addresses global warming by creating carbon-negative building materials. Their unique accelerated CO₂ mineralization technology transforms carbon dioxide into solid building materials, offering on-site production and verifiable carbon sequestration. This method, which accelerates the natural process by 10 million times, has rapidly scaled production. Paebbl’s patented technology and focus on durable, carbon-storing materials position them to significantly reduce carbon footprints in the construction sector.

Innovation

Industry Problem

Paebbl is addressing the massive challenge of global warming, specifically focusing on the excessive volumes of greenhouse gases, particularly carbon dioxide (CO₂), in the atmosphere.

R&D Focus

Paebbl focuses on accelerated CO₂ mineralisation technology to create carbon-storing construction materials. Their R&D lies at the intersection of climate tech, materials science, and industrial decarbonisation. They are pioneering in the niche of carbon-negative supplementary cementitious materials (SCMs), turning captured CO₂ into durable construction inputs, targeting the hard-to-abate construction sector and enabling on-site, verifiable carbon sequestration without reliance on underground storage.

Innovative Solution

Paebbl uses an accelerated CO₂ mineralisation technology that mimics a natural Earth process, turning carbon dioxide into stable minerals. Their solution enables on-site production, eliminating the need for costly CO₂ transport or underground storage. It offers a fully verifiable, permanent carbon sequestration method that combines sustainability with strong, durable building performance, helping industries reduce their carbon footprint effectively.

Solution Effectiveness

Paebbl’s technology accelerates the natural CO₂ mineralisation process by 10 million times, transforming carbon dioxide into solid building materials much faster than nature alone. In just 24 months, they’ve scaled production from grams to hundreds of kilograms of carbon-storing material daily, with plans to reach tons of production per day by early 2025, demonstrating strong readiness for commercial-scale impact.

Star Product

Carbon-Storing Supplementary Cementitious Material (SCM) is the star product as it uniquely stores up to 300 kg of CO₂ per ton, permanently locking carbon in a strong, durable material that matches traditional cement’s performance. It directly addresses construction’s huge carbon footprint by turning CO₂ from a harmful emission into a valuable building resource, making it a game-changer for sustainable construction and climate impact.

Demo Product or Complete Product?

Paebbl’s demo plant began operating in March 2025, marking a major scale-up and proving the technology’s scalability. This plant produces carbon-storing construction materials by permanently mineralizing CO₂, storing up to 500 tonnes annually. Paebbl is using the demo plant to optimize processes and gather data ahead of building its first commercial plant, targeted for completion in 2028.

Future Plan

Market Expansion

– Paebbl plans to build a commercial-scale plant, with partner and site selection already underway, aiming for completion in 2028. – Paebbl plans to bring 1 million tons of their carbon-storing material to the market by 2030, selling both the rock powder and carbon removal credits.
