According to Directive (EU) 2019/904 of the European Parliament and of the Council of 5 June 2019, single-use plastic cutlery, cotton buds, straws and stirrers will be banned in the member states of EU from summer 2021 onwards. Many of them are being replaced by compostable products. The aim of the research was to assess the biological disintegration of selected single-use products under real conditions of urban composting facility. All tested products are established for the Slovak market as 100% compostable by a composting facility. The eight selected products from five different producers were placed into a composting pile of the urban composting facility for 12 weeks. The samples were visually inspected on a regular basis. Temperature and humidity of the pile were continuously measured at the same time. Three samples from each kind of tested product were analyzed, 3 pieces of filter paper were used as the reference samples. The research showed that all tested products were completely or partially disintegrated during the considered period. The average degree of the disintegration of 90% was not reached for one producer only.
