Apart from CO 2 saving (about 60% of the total carbon dioxide emission from a cement kiln is due to limestone calcination), a strong decrease of the kiln thermal input can be obtained inasmuch as most of the energy requirement is represented by the heat of CaCO 3 decomposition. This, in turn, will decrease the fuel-related kiln CO 2 emissions.
