Assessment of waste amounts collected through the public system of waste collection and during clean-up activities in public spaces in Poland

The aim of our study was to estimate the amount of waste disposed through the public system of waste collection, as well as the amount collected during clean-up activities in public spaces in Poland. This study has been the first of its kind in Poland. We defined terminology for the public system of waste collection and public spaces. Our analyses were for the year 2021 and focused on diverse research areas. The administrative and landscape standard was used as a criterion for the selection of the units tested in field trials, by means of a questionnaire survey. 46 units were purposefully selected, and two series of surveys were carried out with respect to two research areas. During the qualitative assessment of our information sources to assess their suitability for the development of the methodology, it was necessary to apply methodological verifiers relating to mass, persons, area, and statistics. The verifiers took into account all variables influencing the quantities of waste considered in the study. The results obtained showed the lack of separate records in the municipal register for the waste assessed under the study. It was found that nearly 85% of the waste collected in the public systems of waste collection and litter in public spaces were registered as mixed (unsorted) municipal waste (Code 20 03 01) [Regulation... 2020]. It was noted that 20% of municipal waste generated outside households was left behind as litter in public spaces and posed environmental risks. For this reason, among others, it was necessary to estimate the amount of this type of waste.
