Cement—the key ingredient that gives concrete its strength—is produced by burning limestone in kilns at 2,300° to 3,000° F (1,260° to 1,650° C). The process typically uses powdered coal or natural gas as fuel, consuming a large amount of energy and releasing carbon dioxide (CO 2 ) from the combustion.
