Frequently Asked Questions

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 microalgae to make our products. These microorganisms are non-toxic and can be grown using only sunlight, water and CO2.

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 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.
