Central Concrete, a unit of U.S. Concrete, has adopted CarbonCure technology to address cement's CO2 emissions. U.S. Concrete has already been working to reduce their carbon footprint via low carbon mix designs. Materials like fly ash can help cut down the amount of cement required. CarbonCure's technology should help decrease emissions even further. The process captures liquid CO2, that would otherwise go into the atmosphere, from industrial sites then injects it into a concrete mixer, where a chemical reaction converts the carbon into a mineral.
Right now, the carbon reduction is relatively small, at 5%. But the startup, which got new funding from the Bill Gates-led Breakthrough Energy Ventures in September 2018, believes that it can double or triple that reduction. Ultimately, it aims to make concrete carbon neutral.Read More
