Separating household waste into fractions at the place where it was generated is one of the most popular methods of collection household waste in most European countries. In 1994 a producer responsibility ordinance for packaging was introduced in Sweden. This ordinance mandates householders to sort out packaging waste, clean the waste and sort different package materials – paper, plastic, glass and metal in assigned recycling bins. Household’s participation is mandatory but in practice it is rarely controlled and enforced.
In our study we have focused our interest on seeing the composition of the “trash bags”, theoretically the rest of the waste after household sorting. The aim of the study was to identify the main fractions of household “trash bags” and the difference in the fraction among 3 different districts in Stockholm, which have practically analogous facilities for separate collection of household waste but rather different socioeconomically characteristics. The chosen districts were located: one in the downtown and two in the suburb districts, one of which has a big multicultural characteristic due to the big amount of emigrants living there.
The results of the study show that the biggest fraction from the composition analyses is organic fraction. This fraction is varying from 48% in the multicultural suburban district to 34% in the downtown. These results show the big opportunity for implementation the separate organic waste collection spatially in the suburban areas of Stockholm. The amount of packaging material in the “trash bags” still composes around 28-50%. The composition of the packaging material differs in the 3 districts
