Experimental evaluation of PCDD/Fs and PCBs release and mass balance of a WTE plant
چکیده انگلیسی

The behaviour of waste incineration plants with respect to organic toxic trace contaminants such as PCDDs, PCDFs and, to a minor extent, PCBs, is still a matter of concern for the public opinion and the decision makers. It is therefore very important, first, to evaluate the release of these organic toxic trace contaminants in the environment during waste incineration, not only through the stack gas emission but also with the solid and liquid residues, and then to compare the total release with the input through the treated waste in order to assess the plant behaviour as a “sink” rather than a “source” of organic toxic trace contaminants. The experimental investigation carried out on an Italian full scale incineration plant has shown a total 17 PCDD/Fs and 12 dioxin-like PCBs release of 5.5–27 μg WHO-TEQ per tonne of treated waste and an input flux of 1.6–44 μg WHO-TEQ per tonne of waste, with the difference between the input and the output fluxes rather small and the plant behaviour toward organic trace toxic contaminants in average neutral. Results are compared with similar evaluations conducted in the last decade on a number of waste-to-energy (WTE) plants operating in Italy.


► An updated assessment of dioxin mass balance on a waste incinerator is reported.
► PCBs are also addressed.
► The role of the APC devises in dioxin partitioning in the residues is emphasised.
► Special attention is given to the characterisation of input fluxes.
