The emissions of cement kilns coprocessing waste derived fuels have the same limits as waste to energy plants. Due to the high temperature and long residence time, as well as to the fact that the lime in the standard suspension preheater is acting as a natural "scrubber", the emissions of heavy metals and/or dioxins is not increased when using waste derived fuels.
