ATLANTA—A Canadian company’s technology for trapping carbon dioxide in concrete will soon find its way into 16 more manufacturing plants in the U.S.

Halifax-based CarbonCure has disclosed a new agreement to roll out its recycling technology to all 22 of of Thomas Concrete Inc.’s American plants. The manufacturer of ready-mix concrete had already been piloting the technology at six Atlanta-area facilities.

“By adding CarbonCure’s technology into 16 more locations, we’re simultaneously reducing our environmental footprint and providing our customers with access to an affordable greener building product across our U.S. markets,” John Cook, technical director for Thomas Concrete USA, said.

CarbonCure’s technology can be integrated into existing concrete manufacturing equipment and stores carbon by injecting it into concrete. For ready-mix varieties, the process works by chemically binding carbonate ions from CO2 with the calcium ions in cement. Along with sequestering the greenhouse gas, the method strengthens the concrete by about 10 per cent while allowing producers to reduce the amount of cement in their mix.

The deal makes Thomas Concrete the Canadian company’s largest client. Other manufacturers using the technology include Ontario’s Brampton Brick and Edmonton’s Northstar Concrete Ltd.

The East Coast company did not disclose the financial details of the deal.
