We turn CO₂ into Future-Proof Building Materials - Permanently.
Why?
With 40 billion tonnes per year, concrete is the most produced material on Earth. Today, it is also responsible for up to 8% of all greenhouse gas emissions, an industry that must decarbonise.
At the same time, humans put a total of 50 billion tonnes of CO₂ into the atmosphere every year. We must do something with all that CO₂ instead of letting it stay in the air.
By turning CO₂ into concrete, building society’s infrastructure becomes an act of climate stabilisation. Paebbl makes advanced carbon-storing construction materials to help make this a reality.

Nature’s Hack. Our Tech.
Paebbl’s technology mimics the way Nature turns CO₂ to stone over centuries. We have taken the same chemistry and with our proprietary technology, accelerated it by 10,000,000 times in a controlled manufacturing process.
The output of this process is a high-performing, carbon-storing supplementary cementitious material, already being deployed in the field in real construction projects.

Paebbl is a company with a time-sensitive mission. As a society, we are already behind in fixing our atmosphere. That's why speed matters. We are focused on delivering a technology scale-up at an unprecedented pace – safely.
Building on 20 years of academic research, Paebbl has gone from grams to kilograms to tons of daily carbon-storing material production within 36 months to meet customer needs and prepare for commercial-scale deployment.
