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. The remaining 60% are “process emissions” — i.e. when limestone is superheated, it releases its carbon atoms and forms CO
