We researched the composition of domestic waste in 2018. The research showed that the share of plastic packages in domestic waste has decreased by 31 per cent compared to the previous research of 2015. The amount of mixed waste has also clearly decreased but due to the large dispersion of measurement data, the result is not statistically significant.  At present, an average of 157 kg per person of domestic mixed waste is generated every year. In 2015, the residents generated on average 177 kg per person of mixed waste in a year. As to the other waste types, there is no significant change.
