The analysis of change in the mass of municipal waste collected in households of individual voivodships, after Poland accession to the European Union was realized in the paper. The estimated mass of waste collected in Poland was about 10 million tonnes per year, 72% of which was from household waste, 23% came from public and commercial waste and 5% originated from municipal services in the years 2005-2015. At the time in Poland, total municipal waste collected in households was resulting in 89% of the mixed waste stream and in 11% of the selected waste stream. The general and periodic changes in the mass of mixed and selected municipal waste collected in households were analyzed on the basis of data by Central Statistical Office. The greatest amount mixed municipal waste was collected in the Masovian Voivodship (15%) and the least in Świętokrzyskie Voivodship (2%), but the majority selected municipal waste was collected in the Silesian Voivodship (17%), whole the least amount – in Podlasie Voivodship (2%). In addition, the maximum periodic and annual rates of change in the mass of collected waste in individual voivodships the years 2005-2015 have also been determined. The greatest increase in the periodic rate of change in the mass of mixed municipal waste was recorded in the Lesser Poland Voivodship (26%) and the biggest decrease in the Świętokrzyskie Voivodship (-15%), while the greatest increase in the periodic rate of change in the mass of selected municipal waste was found in the Lodz Voivodship (22 times) and the smallest increase in the Opole Voivodship (5 times)
