Three startups focused on lowering embodied carbon in concrete are among recipients of 14 federal grants totaling $428 million, the U.S. Energy Dept. announced Oct. 22. The agency's Advanced Energy Manufacturing and Recycling grants are aimed to help the companies build manufacturing facilities.
Terra CO2, which plans to produce supplementary cementitious material that it says can displace much of the portland cement in concrete, will put its $52.6-million grant toward building a plant in Magna, Utah, on the site of Rio Tinto Group’s massive Kennecott copper mine southwest of Salt Lake City. Terra would use mine tailings as feedstock for the plant to produce 240,000 tons of the material per year for the local market.
