We use algae, sunlight, water and sand to produce a bio-cement alternative to traditional cement and concrete that eliminates CO2 emissions.

Concrete And Carbon

The creation of concrete is putting millions of pounds of CO2 in the atmosphere everyday. 

used material on Earth

Concrete is the 2nd most used material on Earth next to water.

of annual global CO2 emissions

Production of traditional portland cement and concrete contributes an astounding 8% of annual global CO2 emissions.

cement sales industry by 2050

The cement industry is projected to grow from $500B in 2020 to $1.0T by 2050

of energy usage in dev countries

50% of energy usage in developing countries is attributable to production of cement and concrete.

Our mission is to make concrete sustainable.

By making bio-cement with zero carbon emissions, we are pushing the world towards sustainability. Our goal is to reduce the global CO2 emissions by a gigaton per year.

Our Technology

Inspired by the composition of coral and seashells, Prometheus Materials is building bio-cement using an exclusive Intellectual Property Partnership with the University of Colorado.
"At Prometheus Materials, we are a team on a mission to make a substantial and meaningful reduction to annual CO2 emissions world-wide."
