ABOUT US

CarbonBuilt’s core technology emerged out of the Samueli School of Engineering and Institute for Carbon Management at the University of California, Los Angeles (UCLA). Led by Gaurav Sant, a third-generation civil engineer, the UCLA team conceptualized the potential to address climate change by embedding industrial CO₂ emissions in the production of concrete in an economically viable fashion. 

 

That core technology has become CarbonBuilt’s Reversa™ process, which injects CO₂ emissions directly from industrial sources (like cement, bio-energy, and natural gas plants) into a new formulation for concrete. CO₂ is absorbed and converted into calcium carbonate (limestone) as it cures permanently storing the emissions in the concrete where they are no longer a threat to the environment. The Reversa process reduces emissions by more than 50 percent relative to traditional concrete production.

 

CarbonBuilt is privately held and led by CEO Rahul Shendure, who has spent 20+ years commercializing sustainable technologies ranging from fuel cells to advanced biochemicals. The growing team includes concrete experts as well as climate tech and heavy industry veterans.

OUR VISION

A world in which global economic prosperity

is no longer a threat to the climate.

 

 

OUR MISSION

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

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

OUR VALUES

  • 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.

  • Transparency. We are forthright with our stakeholders about the opportunities and limitations of our technologies, and advocate for all industry players to do the same.
