Build Greener with
ZEN Carbon
ZEN Carbon is a Kenyan startup pioneering CO₂ mineralization in concrete. We believe the built environment can be more than just infrastructure — it can be a climate solution.
TURN CONCRETE INTO THE WORLD’S LARGEST PERMANENT CARBON SINK
Our technology harnesses the chemistry of carbon mineralization and embeds it into the concrete production process. We partner with concrete plants, real estate developers, and carbon capture companies to integrate our technology seamlessly into their operations.
CO₂ Mineralization
in Concrete
Cement accounts for 80% of the total embodied carbon in concrete production. It is also the most expensive material in concrete production. Our novel technology injects CO₂ into concrete in a process called carbon mineralization.
This happens through a series of precise dosages delivered and timed through our injection technology. The CO₂ reacts with the wet concrete to form CaCO₃ polymorphs at the nano scale. This results in early strength gain in the concrete mix which allows for reduction of the cementitious content in the concrete mix while maintaining the same performance and integrity.
Our process has been rigorously tested in alignment with various methodologies to ensure value is delivered.
Our MRV system tracks the amount of CO₂ injected and permanently stored in the concrete mix down to the gram level through real time sensor integration and analytical methods.
EARLY STRENGTH GAIN
CO₂ mineralization forms stable mineral phases in wet concrete that accelerate early strength gain, enabling reduced cement content without compromising performance or durability.
Strength Meets Innovation
Stronger & Smarter – Higher performance with less cement, delivering cost savings without compromise.
Built to Last – Denser, more durable concrete reduces cracking, maintenance, and extends lifespan.
What We Offer
