We offer concrete makers the process, materials and support to produce higher-quality concrete that uses no cement, costs less to make and reduces their carbon footprint. Conventional concrete is made with cement, the production of which accounts for nearly 10% of the world's CO2 emissions! We've replaced cement in the mix with steel slag, industrial waste that is far cheaper than cement. Using carbonation activation, CO2 is injected into the wet concrete to give it its strength. Because we capture and permanently sequester CO2 in the concrete, these products are carbon-negative. Our patented technology can be implemented in any concrete products plant.
