This results in the production of cement clinker, an intermediate product in the manufacturing process. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat the kiln account for about 40% of cement-manufacturing emissions.
