The latest VC money for cleaner concrete

CarbonBuilt, a Los Angeles startup with tech to embed CO2 in concrete, just raised $10 million in Series A funding, Ben writes.

Why it matters: It’s among several startups attracting capital to make climate-friendly concrete and cut the massive emissions from the production of cement, a key concrete component.

Driving the news: Neglected Climate Opportunities, a VC arm of the Grantham Environmental Trust, led the funding round. Other backers include Pritzker Group, Lime Street Ventures and Climate Capital.

How it works: CarbonBuilt, spun out of UCLA, has developed a concrete mixture that requires less cement, and a curing process that embeds CO2 captured from industrial streams but could also come from direct air capture.

«Together, these changes result in a 10 to 30 percent reduction in raw material costs and a 60 to 90 percent reduction in carbon dioxide emissions,» the company said.

The big picture: Multiple companies are developing and commercializing climate tech in the concrete and cement sectors. They include…

  • Solidia Technologies, which has a lower-CO2 cement-making process and embeds CO2 in concrete curing, announced $78 million in new funding in April. Backers include Imperative Ventures, Bill Gates” Breakthrough Energy Ventures, BP, John Doerr and others.
  • In May, the Ireland-based «green cement» company Ecocem Materials announced a $27 million investment by Breakthrough. CarbonCure, another company that embeds captured CO2 into concrete, is backed by Amazon, Microsoft and Breakthrough.
