The planet uses four gigatons of cement a year, which requires that the limestone be heated to over 2700 degrees in a chemical reaction that releases vast quantities of CO2. Until now.
CarbonCure is developing a technology that uses carbon dioxide captured from various waste emissions, such as ethanol and ammonia, to lower emissions. This process makes the concrete stronger and helps eliminate carbon dioxide that would otherwise be released into the atmosphere.
CarbonCure hopes to attain a 500-megaton-per-year reduction in embodied carbon – the equivalent of taking 100 million cars off the road.
