Dartmouth-based CarbonCure Technologies, creator of a process that buries carbon dioxide in concrete, has partnered with St. Louis-based Breckenridge Material Company and Eastern Missouri Concrete to lift its number of concrete-producing partners above 80.
The new partnerships allow the American companies to recycle waste carbon dioxide into concrete to increase its environmental, material, and economic performance, CarbonCure said in a release.
The rapidly growing company said the CO2 is permanently converted into a solid mineral within the concrete, and the addition of CO2 also improves the compressive strength of the concrete, allowing producers to unlock operational savings.
The release said CarbonCure is part of a growing industry of CO2-utilization technologies that aim to reduce global greenhouse gas emissions by 15 percent by 2030.
CarbonCure’s concrete-producing partners include several of the world’s largest vertically integrated cement and concrete companies.
CarbonCure is one of 23 semi-finalists in the $20 million NRG COSIA Carbon XPRIZE challenge, which has been called the Nobel Prize for climate technologies.
A family company for four generations, Breckenridge supplies aggregates, ready mix concrete and building materials to customers in metropolitan St. Louis. The company has recently quadrupled in size and reached a revenue of over US$100 million. In partnership with CarbonCure, they seek to increase their share of the growing green building market in the St. Louis area.
Eastern Missouri Concrete has been supplying ready mix concrete to customers in the St. Louis metropolitan area and surrounding communities since 2008.
