Turning carbon into stone.
We grow carbon-negative minerals using algae and sunlight — a new source of limestone for sustainable construction.
Carbon removal, built in.
Our product is adapted to a wide variety of applications, both industrial and domestic.
Every tonne of our biominerals permanently stores captured CO₂ while replacing materials that would otherwise emit it.
By merging biology and industry, we create value where others see waste, proof that climate impact can scale through everyday materials.
