Summary:

Despite the introduction of a common and uniform system of fees for the collection and management of Municipal Solid Waste (MSW) throughout Poland, new illegal waste dumping sites continue to be created in areas not designated for this pur-pose. The main aim of the work was focused on determine the material composition of the waste deposited (and found) on these wild dumping sites in the Trzebinia commune, as well as to conduct a spatial inventory of these locations. The aim was ac-complished through the use of a specialized questionnaire. In to-tal, 21 illegal dumpling sites were identified, despite the fact that the Municipal Waste Selective Collection Point (PSZOK) is available in the commune. The majority of these illegal landfills were found in areas covered with trees (30.8%) and bushes (42.3%). None of the illegal landfills contained more than 1 Mg of MSW. The average weight of waste deposited in illegal land-fills was 98.5 kg per site. The largest proportion of waste found at these illegal sites consisted of demolition and construction waste, such as rubble (34.3%) as well as plastic waste (32.9%). The share of rubble and construction waste increased with dis-tance from buildings. Only four of the twenty-one illegal land-fills were removed during the sixteen months of research.
