This project reduces or eliminates concrete’s cement ingredient—responsible for about 7% of global emissions—and replaces it with low-carbon, mostly waste materials. It is one component of CarbonBuilt’s XPrize-winning technology that reduces the embodied carbon of concrete products by 70-100+% with no impact on price, performance, or plant operations.

CarbonBuilt is partnering with existing concrete products producers, including an Alabama block plant, to integrate this technology. The plant is currently being retrofitted, with plans to have very low-carbon blocks (80%+ reduction) available for purchase in Q1 2023. Subsequent plants around the country are in negotiation.

Revenue from carbon credits will be shared with CarbonBuilt’s historically risk-averse concrete producer partners to grow their margin post-retrofit and make a stronger financial case for accelerating adoption.
