At Prometheus Materials, we provide sustainable building materials that accelerate the world’s transition to a carbon-negative future. Inspired by nature, our unique process combines naturally occurring microalgae with other essential components to create a bio-cement. When mixed with aggregate, it forms a zero-carbon bio-concrete with mechanical, physical and thermal properties that are comparable or superior to portland cement-based concrete. Virtually all of the water used in creating our bio-cement is returned to the earth via dehydration.
Our building materials both AVOID the carbon-intensive operations involved in manufacturing and transporting traditional cement and SEQUESTER embodied carbon from microalgae and biomineralization.
