GASEOUS POLLUTANT EMISSIONS FROM BURNING ANIMAL BY-PRODUCTS

Gaseous emissions during thermal animal waste treatment in a meat production plant have been determined. A dry flue gas system with a multisectional bag filter was installed at a meat production plant. Animal waste was incinerated in a rotary kiln, the capacity of the plant was 700 kg/h. The average thirty-minute (1352 samples) emission values of volatile dust, total organic carbon (TOC), hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur dioxide (SO2), nitrogen oxide (NO), nitrogen dioxide (NO2) and carbon oxide (CO) were obtained during a study period of 1 month. Specific samples were collected to determine dioxin, furane, heavy metal, mercury, cadmium and thallium concentrations. Histograms of the obtained results were prepared, and the results were compared with the permissible emission levels defined by the European Union. Additionally, justification was provided when the observed values exceeded the levels defined by the European Union.
