CarbonCure is a technology that injects a small amount of recycled CO2 into concrete during mixing thereby creating stronger concrete. Some cement that can be saved to create the same strength concrete, thereby reducing the carbon footprint (emodied CO2) of the concrete mix.
Below is a press release for CarbonCure, announcing adoption of the technology in 15 additional mid-west ready mix concrete plants. That makes a total of 126 plants in the U.S. and Canada using CarbonCure. That's not a many of the estimated 5,500 plants, but the technology is win-win in terms of economy and sustainability, according to Jeff McPherson below.
For example, there is one data point is mentioned below. Irving Materials saves 25 pounds of carbon dioxide per cubic yard. When comparing the 650 pounds of carbon dioxide produced by a 4,000 psi class mix for the Great Lakes Midwest Region (as indicated in the
NRMCA Benchmark Life Cycle Assessment Report), this amounts to about a 5% reduction in carbon dioxide per cubic yard. That might also be percent cement savings by Irving Materials.
Here in Seattle, I attended a mixer hosted by Praxair (CO2 distributor) and CarbonCure to encourage local ready-mix plants to adopt their technology. With Seattle being a key market for sustainable products, that adoption seems likely, but no announcements have been made yet.

Irving Materials, Inc. adds CarbonCure
CO2 recycling technology to 15 ready mix concrete plants
GREENFIELD, INDIANA – Irving Materials, Inc. (imi), a concrete and
materials provider headquartered in Greenfield, Indiana, has adopted the CarbonCure CO2 recycling technology
in 15 of its ready mix concrete plants across Indiana, Kentucky and
Tennessee.
On average, every cubic yard of
concrete made by imi Concrete with the CarbonCure Technology will save 25
pounds of carbon dioxide (CO2), reducing the carbon footprint
of its concrete.
The CarbonCure Technology, which is being installed in 15
imi concrete plants, injects recycled CO2 into the concrete
mix to improve the manufacturing process and reduce the concrete's carbon
footprint.
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.

Founded in 1946, imi Concrete operates
155 active ready mix concrete plants across Indiana, Kentucky, Tennessee
and Ohio.
imi Concrete first installed the
CarbonCure Technology at its Whiteland, Indiana plant in July 2017, where
it conducted extensive testing. The company initiated its expanded
coverage of the carbon-reducing technology with 3 plant installations in
November 2018. A further 11 plants are scheduled for installation in
early 2019. Developers and contractors will be able to access concrete
made with recycled CO2 from select imi Concrete locations by
early spring.

Jeff McPherson, VP Sales &
Marketing, remarks, “At the end of the day, what matters to our
customers is: Does the concrete meet structural performance and
construction requirements and does it make good business sense?
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.”

The CarbonCure Technology is available
in 126 concrete plants across the United States and Canada. The company
recently announced its initial foray into international territories with
an additional 3 plant installations at Pan-United, the leading concrete producer
in Singapore. CarbonCure is a finalist in the $20 million NRG COSIA
Carbon XPRIZE challenge, and has been named a Cleantech Group Global 100
company for the past 3 years.
