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.
