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 requirements, they knew that their technology could also impact the civilian world and potentially shift the course of climate change. By harnessing microalgae as a living building material, they created a replacement for carbon-intensive portland cement. In 2021, Prometheus Materials was founded – and our zero-carbon bio-concrete 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 an ultra 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 bio-concrete 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 secured, 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 masonry unit) and ASTM C129 (nonloadbearing masonry unit) – marking a significant step toward commercialization.

“Our unique process harnesses the abilities of naturally occurring microalgae along with other essential components. It's basically the same way that nature creates seashells and coral reefs – only accelerated to a degree that makes the production of our zero-carbon bio-cement an effective and efficient solution. We both avoid the carbon-intensive operations involved in manufacturing and transporting traditional cement and sequester embodied carbon from the microalgae and biomineralization.”
