In Slovenia, slightly more than 106,000 tonnes of municipal waste were landfilled at 10 non-hazardous waste landfills in 2023, compared to slightly more than 90,000 tonnes the year before. The increase in landfilled municipal waste in 2023 was the result of the extensive floods that hit Slovenia during the summer of that year.

The share of landfilled municipal waste at the EU level in 2023 was 22% of generated municipal waste. The countries in which more than half of generated municipal waste was landfilled include Greece, Romania, Malta, Cyprus, Portugal, Hungary, and Bulgaria.

In Slovenia, just over 1.1 million tonnes of municipal waste were generated in 2023, which is 7 % more than the previous year, of which 69 % was collected separately. 26 % of municipal waste generated was packaging waste. In 2023, more than 294.000 tonnes of packaging waste were generated in Slovenia, of which more than one fifth was plastic packaging waste.

The share of waste electrical and electronic equipment (WEEE) disposed of within mixed municipal waste annually in the period 2020-2023 represented an average of 0.8% of collected mixed municipal waste. The share of waste batteries and accumulators (WBAs) was even lower, representing an average of 0.03% of all collected mixed municipal waste in the same period annually. The amount of separately collected WEEE has been increasing over the years. In Slovenia, just over 16,600 tonnes of WEEE were collected separately in 2023, which is almost 8% more than in 2022.

In recent years, the number of sampling sites where individual pesticides exceed the quality standard has been decreasing. The concentration of pesticides in groundwater is also declining. However, in areas of Slovenia characterized by intensive agricultural activity, some pesticides still exceed the quality standard.

The average occupancy rate of cars in Slovenia is declining. In heavy goods transport, average occupancy is increasing as a result of the growing share of tractor units in freight transport, which have a higher load capacity. The NEPN emphasizes the importance of increasing vehicle occupancy – e.g., by promoting carpooling, developing appropriate infrastructure, and organizing freight transport more efficiently—as an important contribution to reducing GHG emissions and energy consumption, while governing transport demand and shifting to more sustainable forms of transport.
