CarbonBuilt’s Reversa™ process transforms carbon dioxide (CO₂ ) taken directly from industrial processes, biomass boilers, or emerging direct air capture solutions into a low carbon, but otherwise "no compromise", precast concrete product.


Reversa's breakthrough use of low cost and low carbon materials enables this capital and energy efficient curing process to deliver a 70-100%+ reduction in concrete's carbon footprint along with a 30%+ financial return.


A world in which global economic prosperity

is no longer a threat to the climate.




To enable concrete manufacturing to drive large-scale greenhouse gas reductions

through the cost-effective utilization of CO₂ and other industrial waste.


  • Optimism. Our innovations can and will have a transformative impact on ensuring the sustainability of our world.

  • Engineering for Impact. An innovation isn’t a success unless it is commercialized. We focus on breakthrough inventions that will make a difference to the world we live in.

  • Performance & Functionality. We build products that deliver the performance our customers require as well as significant environmental, economic and societal benefits.

  • Diversity. We have a responsibility to create opportunities for women and people of color within our company and thus serve as a model for the construction industry.
