Prometheus Materials develops ProZERO™, a supplemental blend designed to decarbonize the construction industry by replacing cement. This bio-material utilizes microalgae to capture carbon and avoids traditional high-heat cement production processes. The resulting concrete products offer performance comparable to traditional materials while achieving carbon negative status.

Problem
The production of traditional cement is a major contributor to global carbon emissions, accounting for approximately 8% of the total, due to energy-intensive processes like limestone mining and high-temperature kilns. The increasing demand for concrete, driven by global construction, exacerbates this environmental impact.
Solution
Prometheus Materials offers ProZERO™, a carbon-negative cement replacement designed to reduce the environmental impact of concrete. ProZERO™ uses microalgae to organically generate limestone through biomineralization, avoiding the need for traditional limestone mining and high-temperature industrial kilns. The microalgae captures carbon through photosynthesis, and this carbon is then stored within the final building product. ProZERO™ can be used as a supplemental blend, replacing cement in a 1:1 ratio, allowing users to adjust the amount of cement replaced to meet specific carbon reduction goals.
Target Audience
The primary target audience includes architects, engineers, suppliers, building owners, and construction firms seeking to reduce the carbon footprint of their projects.
