About Greenmixes
GreenMixes is developing carbon-negative admixtures that transform concrete into a climate solution. Concrete is responsible for more than 8% of global CO₂ emissions. Our technology, developed by researchers from the University of Cambridge, uses biomass waste-derived materials to permanently store atmospheric carbon within concrete, turning the world’s most used material into a carbon sink. The result is a scalable, drop-in additive that cuts emissions without compromising strength, cost, workability or process. By collaborating with industry partners, GreenMixes is helping the construction sector move from carbon-intensive to carbon-negative, one mix at a time.
