Co-processing PCB and other POPs in cement kilns. A local solution.

Waste co-processing in a cement kiln allows you to destroy almost fully organic materials (including persistent organic pollutants, POPs) that may present in alternative fuels. If the co-processing of POPs such as polychlorinated biphenyls (PCBs) is carried out in a kiln for the first time and there is insufficient data on the efficiency of their decomposition, trial clinker firing is carried out testing the level of pollutant emissions into the atmosphere. The article describes the procedure for trial firing with a PCB combustion. An example of such testing shows that PCBs are effectively destroyed in a kiln, while pollutant emissions are stable and the quality of clinker and cement is not reduced.
