Learn more about CCP use in Texas Texas Coal Ash
For example, each ton of Fly Ash used to replace a ton of cement saves the equivalent of one barrel of oil required to produce the cement. Cement and lime are the third most energy-intensive materials to produce on a per ton basis, next to steel and aluminum. CCP recycling reduces Greenhouse Gas emissions from the manufacture of cement and lime.
