Many industrial manufacturers, including cement and concrete producers, are seeking solutions to reduce the carbon footprint of their products. In collaboration with these producers, we recognized that the fastest path to a low-carbon material was to develop a solution that did not require novel materials, new processes, and expensive technologies. So, we set out to develop a proven, familiar material to speed market adoption and accelerate global decarbonization. The solution—a carbon-negative limestone.Ìý

Second to water, concrete is the most used material on the planet, so finding a sustainable way to make concrete is critical. Minus Materials looks to do just that, by using algae to grow limestone for concrete production. The company is led together by Sarah Williams (CU Â鶹ӰԺ Materials Science & Engineering, '22) and Wil Srubar (CU Â鶹ӰԺ College of Engineering & Applied Science). The Minus Materials team participated in a Six-Pack Startup Challenge that Venture Partners at CU Â鶹ӰԺ offered in 2020Ìýand won the Lab Venture Challenge (LVC). Minus Materials has since participated in Indie Bio.
