In the next 40 years, we’re set to double the amount of infrastructure in the world — equivalent to a new Manhattan every month. A lot of this is crucial to the energy transition, but all of it will require steel and cement. These two materials represent 15% of global emissions.

We’re committed to tackling the climate emergency by decarbonising heavy industries and creating low-carbon construction materials. Our patent-pending process captures CO2 and upcycles by-products from steel manufacturing into a cement alternative.

We’re a small, but mighty team (and growing), backed by world-class investors in climate, hardware and industrial decarbonisation.
