CarbonCure's carbon dioxide removal (CDR) technology offers permanent, verifiable, and scalable carbon reductions for the concrete industry. The retrofit technology is installed in hundreds of concrete plants globally, and the company is continuing to launch new innovative products and technologies. CarbonCure's technology won the grand prize in the $20 million NRG COSIA Carbon XPRIZE competition, selected as the most scalable breakthrough technology to convert CO2 emissions into usable products. CarbonCure was also recognized as Cleantech Group's North American Company of the Year in 2020.
This project addresses one of the construction industry's most pressing environmental challenges. Concrete is the most widely used man-made material in existence, with Portland cement as its primary ingredient responsible for approximately 8% of global CO2 emissions. If the cement industry were a country, it would rank as the third largest carbon emitter worldwide, behind only China and the United States. The CarbonCure process works by retrofitting existing concrete manufacturing facilities with modular CO2 injection equipment that captures waste CO2 and permanently mineralizes it into ready-mix concrete during production. The technology injects approximately one pound of CO2 per cubic yard of concrete, where it undergoes a chemical reaction that permanently binds the carbon within the concrete matrix while also reducing the amount of Portland cement required.
This grouped project operates across 43 concrete facilities throughout the United States, with initial installations in Georgia, North Carolina, and South Carolina, and is designed to expand nationwide. All enhanced concrete maintains identical performance standards to traditional concrete, meeting ASTM certification requirements. Over its seven-year crediting period, the project is expected to achieve approximately 366,400 metric tons of CO2 reductions through permanent carbon sequestration and reduced cement consumption.
