CarbonCure injects CO2 into concrete to sequester it ...

Cement is responsible for 7 per cent of global greenhouse emissions, the second largest industrial source. CarbonCure came up with a method to trap CO2 emission forever, while also reducing the need for cement to make strong concrete. The system takes captured CO2 and injects it into concrete during the mixing phase. The carbon dioxide reacts ...

CO2 Curing of Concrete Blocks

To sequester carbon dioxide (CO2) as part of a global atmospheric stabilization strategy, CO2 can be used to cure cement-based materials. For example, manufacturers of concrete masonry units could sequester CO2, reduce energy consumption, and reduce the associated generation of CO2 by switching from current steam curing processes to a CO2 ...
