Abstract |
This study was performed to evaluate the emission concentrations of PCDDs/DFs (polychlorinated dibenzop- dioxins/dibenzo-furans) emitted from the stacks of various municipal solid waste (MSW) incineration plantsand estimate emission factors considering several operation parameters. MSW incineration plants were classifiedinto 3 groups (i.e., large, medium, and small), according to their incineration capacity per day. The average
emission concentrations of PCDDs/DFs were 0.014 ng-TEQ/Nm3 in large-scale incineration plants, 1.203 ng-TEQ/Nm3 in medium-scale incineration plants, and 15.317 ng-TEQ/Nm3 in small-scale incineration plants. Emission factors for each scale of incineration plants were estimated to 0.09, 9.05, and 176.43 per tonne of waste burned, respectively. In particular, large-scale incineration plants showed the positive relationship between TEQ concentrations of PCDDs/DFs and emission factors (R2= 0.8775). These results can be used for the estimation of emission amounts from MSW incineration plants into ambient air. |
