Prometheus Materials, founded by CU Â鶹ӰԺ professors, has developed eco-friendly cement to combat the significant carbon footprint of traditional cement production. Their technology, supported by a Department of Defense project, minimizes carbon emissions and recycles water. Transitioning from research to commercialization, the Colorado-based company now produces bio-concrete using blue-green algae, akin to natural processes forming sea shells and coral reefs.
