Portland cement – the primary ingredient in concrete – accounts for ~7% of global CO2 emissions. The majority of those emissions stem from the calcination of limestone (60%). Approximately 30% is attributable to the emissions from fuel combustion. The remaining 10% is due to the emissions from the electricity needed for grinding and blending clinker.

No; We do not use portland cement in the manufacture of our building products. Instead, we use a patent-pending photosynthetic biocementation process. In fact, our products can be produced with net-zero embodied carbon emissions.

Our patent-pending photosynthetic biocementation process results in the production of biomineralized composites suitable for construction in less than one day.

We use a variety of biomineralizing cyanobacteria, also called blue-green algae or microalgae, to make our products. These microorganisms are non-toxic and can be grown using only sunlight, seawater, and CO2.
We rely on a natural, photosynthetic process to manufacture our products, which can be produced with net-zero embodied carbon emissions (LCA Stage A1-A3) inclusive of biogenic carbon.

We are currently producing microalgae-based concrete masonry units (CMUs) that conform to ASTM standards. We will be introducing additional pre-cast and ready-mix products in the coming months.

We have achieved compressive strengths of approximately 2000 psi, which meet numerous ASTM standards for both structural and non-structural applications. Higher compressive strengths will be achieved through continued development.

We do not use portland cement in the manufacture of our building products. Instead, we use a patent-pending photosynthetic biocementation process, which is similar to the natural formation of strong, tough minerals in seashells and coral. Instead of emitting CO2, we sequester and store CO2 in our products.

The tensile behavior of our products is also unique, unlocking new opportunities for structural and non-structural applications.

We are currently serving customers in North America. We welcome inquiries from licensing partners to help us expand our operations to serve customers in other parts of the world.
