The article presents the results of the analysis of morphological composition of municipal waste collected selectively in two municipalities: a large rural municipality in the Mazovian voivodeship and a rural-urban municipality located in the Lubelskie voivodeship. The segregated waste collection systems were practically the same in both communities. The collected waste was sorted into five basic fractions (plastic, metal, paper and cardboard, composite packaging, and glass) and divided into 17 sub-fractions. In total, over 400 Mg of waste was analysed in terms of its morphological composition. The process of separating selected fractions was performed by manually sorting the packaged waste. The study was conducted in the course of four months of the summer of 2015 and was aimed at examining the composition of waste depending on the type of municipality. The presented analyses showed no significant differences in the morphological composition of waste in both municipalities, and revealed mixed waste paper as the dominant fraction. The study showed, however, the problem of improper waste segregation at source.
