The Golden Startup, based in Colorado, recently closed a series B of $ 124.5 million in order to launch its replacement with low-carbon cement cement.
Cement – the stuff that binds to concrete in the aggregate – the climate weighs strongly. The CO2 Published by the chemical reaction, the Portland cement, the most common type of cement, and the fossil fuels, which typically make up around 8% of all carbon pollution.
For this reason, a number of startups examined paths to achieve the same rocky results without pollution. In addition to Terra CO2, Furbo, Sublime Systems, Partanna and Phnx materials, all different approaches have to solve the problem.
SCM is a broad class of materials that serve to replace Portland cement without affecting the properties that make specifically appealing. Terra CO2 produces a version of SCM that cooks widespread silicate rocks until they melt in glass. The glassy powder react similarly to Portland cement.
The startup said that it will use the new financing to build a massive system near Dallas, in which 240,000 tons of its supplementary cement material (SCM) can be equipped annually.
The new financing round of Terra CO2 was jointly directed by Bill Gates' groundbreaking Energy Ventures, Eagle Materials, Temasek-supported Genzero and Al Gores Just Climate. Barclays Climate Ventures, Cemex, Prologis and Siemens Financial Services took part.
According to Terra CO2, its SCM can replace up to 40% of the Portland cement used in concrete. It also works on a next generation of its product that can completely displace traditional cement. Compared to Portland Cement, the SCM of the startup creates 70% less carbon dioxide.
