Conditions occurring in cement rotary kilns assure high destruction and removal efficiency (DRE) of the most stable substances, efficacious dry sorption of acid gases in the alkaline raw meal and heavy metals bounding in the clinker. Adequate operation of hazardous waste incineration in the process connected with cement clinker production does not cause increasing air pollutant emissions. Magnitude of the emissions often does not depend of this if there are using wastes in the cement kiln at all. The work presents a review of DRE levels and stack emissions for selected flue-gas constituents during hazardous waste co-combustion in cement kilns with regard to such substances as THC, PCB, PCDD/PCDF, CFC, heavy metals and other gaseous and dust air pollutants.
