Carboncure Technologies of Dartmouth has announced its client Irving Materials, Inc. of Greenfield, Indiana, is adopting the Carboncure technology at 11 of its plants in the coming months.

Irving now uses the technology at four plants, and the expansion brings the total to 15. It is a major expansion of Carboncure’s customer base, given that the system is now used at a total of 126 plants.

Carboncure execs have said before that many of its major customers are using the technology at one or two plants, even though they have several plants that could use it. As well as bringing on new clients, the company has been working at getting existing companies to implement the system at more than one site.

Irving, which goes by the brand name imi Concrete, was founded in 1946 and operates 155 active ready-mix concrete plants across Indiana, Kentucky, Tennessee and Ohio. The company said that every cubic yard of concrete it makes with the CarbonCure technology will save 25 pounds of carbon dioxide, reducing the carbon footprint of its concrete.

“Imi Concrete has been at the forefront of concrete innovation, including the development of the front discharge concrete mixer that is now an industry staple,” Bob Haldrup, imi North Division President, said in a statement. “CarbonCure fits within our vision to lead our industry with forward-thinking processes that provide better products for our customers.”

The CarbonCure Technology works by injecting recycled post-industrial CO2 into concrete during the manufacturing process. The CO2 undergoes a mineralization process that enhances the concrete’s compressive strength, which enables concrete producers to optimize concrete mixes without impacting the concrete’s quality or price.

Imi Concrete first installed the CarbonCure Technology at its Whiteland, Indiana, plant in July 2017, where it conducted extensive testing. This past November, it added three more plants, and will now have more plants using the technology by early spring.

“CarbonCure enables us to produce the same high-quality concrete that our customers have relied on us to provide for the past seven decades, but now with a reduced environmental impact,” said Jeff McPherson, Vice-President of Sales and Marketing.

CarbonCure recently announced its international expansion as Pan-United, the leading concrete producer in Singapore, agreed to install the technology at three plants. CarbonCure is a finalist in the US$20 million NRG COSIA Carbon XPRIZE challenge, which will be decided next year.
