Thermal waste treatment processes are a feasible option after recovery (collection, sorting, recycling) and prior to controlled disposal. Monitoring data at a hazardous waste incineration plant made it possible to calculate three heights of the incinerator emission network. The incineration plant is thus operated in such a way that the emissions of the harmful substances of the chimney are in conformity with the VLE values transposed into the national legislation by Law no. 278/2013 regarding industrial emissions, Annex 6. Three methodologies are used to determine the height of the chimney: according to the Technical Instructions for Air Quality Control - "TA Luft", according to "Arrêté du 25/01/91 relatif aux incinération de résidus urbains" and according to "RS 814.318." 142.1 Ordonnance sur la l'air (Opair) ".ChimneyIncinerationMonitoringWaste treatmentSymposium Proceedings10.21698/simi.2018.fp55
