Our Technology
We’ve developed a biological process that converts captured CO₂ into solid minerals. By cultivating mineral-forming macroalgae, we reproduce nature’s carbon cycle under controlled conditions, transforming emissions into stable, high-purity carbonates for industrial use. Our materials offer a scalable, low-carbon alternative to mined minerals across multiple sectors.
Capture → Grow → Mineralize → Build → Recycle.
Capture → Grow → Mineralize → Build → Recycle.
Stage 1: CO₂ Capture
We begin by introducing an external alkaline component (which has a high level of calcium) into seawater, triggering the absorption of CO₂.
This step creates a carbon-rich solution, marking the starting point for our minerals.
Stage 2: Biomineralization
In open ponds, our macroalgae use this dissolved CO₂ to grow and naturally produce ultra-pure calcium carbonate through biomineralization.
Through photosynthesis and controlled chemistry, biology becomes the engine of mineral creation.
Stage 3: Separation
Here, biology completes its transformation of CO₂ into stone: permanent, inert, and ready to be used as a building material.
As the algae grow, mineral crystals form, similar to those from processes observed in shells, corals and limestone, and are recovered through a simple, low-energy process without filtration or centrifugation
Stage 4: Build a New Future
This ultra-pure calcium carbonate, produced in our ponds, can replace conventionally mined minerals in a wide range of industrial applications.
Instead of compressing, liquifying, transporting and storing CO2 underground, our macroalgae produces carbon-negative minerals that re-enter industrial supply chains, in cement, coatings, paper, and packaging, locking away CO₂ permanently while maintaining the performance industries rely on.
From pond to powder to product, we close the loop, transforming emissions into the building blocks of a low-carbon world.
