Concrete was about millennia, but Terra CO2 Thinks it has a better way to make the almighty building material, and investors seem to agree.
The Golden, Colorado-based startup has recently closed a $ 124.5 million series B to help bring its low-carbon cement replacement to market.
Cement – the things that link aggregation to form concrete – weigh a lot on the climate. The co2 Released from the chemical reaction that makes Portland cement, the most common type of cement, and the fossil fuels, which typically power it is responsible for about 8% of the total carbon contamination.
This is why a range of startups have explored ways to get the same rock-solid results without the contamination. In addition to Terra CO2, Open,, Sublime systems,, Partanand Phnx materials Everyone has different approaches to solve the problem.
SCM is a wide class of materials that serve to replace Portland cement without sacrificing any of the qualities that attract concrete. Terra CO2 makes a version of SCM, which cooks widely available silicate rocks until they melt in glass. The glass powders react in the same way as Portland cement.
The startup said it would use the new funding to build a mass facility close to Dallas capable of pushing 240,000 tons of its supplemental cement materials (SCM) annually.
Terra CO2’s new financial circle was co-led by Bill Gates’ open energy ventures, Eagle materials, Temsek-supported Genzero, and Al Gore’s fair climate. Barclays Climate Ventures, Cemex, Prologis, and Siemens Financial Services participated.
Today, Terra CO2 says its SCM can replace up to 40% of the Portland certificate used in concrete. It also works on a subsequent generation of its product, which can completely move traditional cement. Compared to Portland cement, the SCM of the runway generates 70% less carbon dioxide.
