CarbonBuilt enables concrete manufacturing to drive large-scale greenhouse gas reductions through the cost-effective utilization of CO₂ and other industrial wastes.
Market:CarbonBuilt offers the concrete industry reduced environmental impact, greater customer demand and increased profitability, while providing heavy industry (e.g., power plants and cement kilns), a low cost pathway to reduce their CO2 emissions. The impact of the technology is conditioned by the global concrete market (TAM: over 20 billion tons produced and $1.2 trillion revenue). CarbonBuilt’s initial segment of prefabricated concrete blocks comprises $5 billion within the USA.
Technology:CarbonBuilt’s ReversaTM platform, which was developed over the course of seven years at UCLA’s Institute for Carbon Management, includes innovations to both the concrete mixture design and the curing process. Reversa formulations includes hydrated lime, a widely-available commodity chemical used in a wide range of applications, and enables increased and more flexible use of waste materials like fly ash. In Reversa’s curing process, CO2 contained within dilute flue gas streams (with no requirement for capture or purification) is permanently sequestered into the concrete. Together, these innovations enable concrete manufacturers to significantly reduce the carbon footprint of their products in a manner that increases profitability.
