Approaching a Zero-Carbon Future

In April 2016, a team of biotechnology and engineering professors at the University of Colorado Boulder responded to a Department of Defense initiative related to engineered living materials – and the seed of what would become Prometheus Materials was sown.

While the team’s results more than satisfied the project’s requirements, they knew that their technology could also impact the civilian world and potentially shift the course of climate change. By harnessing microalgae to be used as a living building material, they constructed a replacement for carbon-intensive portland cement. In 2021, Prometheus Materials was founded – and our zero-carbon concrete alternative is currently in production.


Pathway To Prometheus

Mixing ingredients in the lab to make Prometheus concrete.

Department of Defense Initiative

Our founders achieved groundbreaking results for the DoD Biological Technologies Office – harnessing natural components to produce a low-carbon concrete alternative.

Formed Company

Prometheus Materials was founded, seed capital was raised and intellectual property was licensed from the University of Colorado – attracting the attention of major architectural and technology firms.

Microsoft Pilot

Prometheus Materials manufactured our zero-carbon concrete alternative for a pilot project. MS builds 50-100 data centers each year – and we expect to play a much larger role in their construction.

Series A Funding

$8 million in financing was closed, led by Sofinnova Partners with participation from Microsoft Climate Innovation Fund; Skidmore, Owings & Merrill (SOM); GAF and the Autodesk Foundation.

ASTM Certification

Prometheus Materials completed the testing and certification process for ASTM C90 (loadbearing CMU) and ASTM C129 (nonloadbearing CMU) – marking a significant step toward commercialization.

“Coral reefs, shells, and even the limestone we use to produce cement today show us that nature has already figured out how to bind minerals together in a strong, clever, and efficient way. By working with nature to use existing microalgae to bind minerals and other materials together to create new types of sustainable biocomposite building materials, we can eliminate most, if not all of the carbon emissions associated with traditional concrete-based building materials."
