The proportion of WEEE disposed of within mixed municipal waste is decreasing, while the proportion of WBA disposed of within mixed municipal waste is very low and does not change significantly over the years. On the other hand, the amount of separately collected WEEE is increasing. Almost 15,500 tons of WEEE were collected separately in Slovenia in 2022, which is 7% more than in 2019.

In 2023, around 182 million pieces of plastic carrier bags were placed on the Slovenian market, of which 99% were those with a wall thickness of less than 50 microns (light plastic carrier bags). In Slovenia, the consumption of lightweight plastic carrier bags amounted to 85 bags per capita in 2023 In the same year, 145.9 million pieces of single-use food containers made wholly or partly of plastic and 174.4 million pieces of single-use beverage cups made wholly or partly of plastic were placed on the Slovenian market.

Various measures have been taken that waste is destined for recovery, giving priority to recycling and preparation for reuse. Data on waste generation and management is being collected to monitor their implementation.

The amount of waste from coal combustion is decreasing as a result of the reduction in the use of coal for electricity generation. In 2022, the amount was 15% lower than the previous year. By far the largest source is the Šoštanj thermal power plant. Most of the waste is used as fill material in mines.

Over the period 1990-2022, the amount of spent nuclear fuel, the only high-level radioactive waste, increased at an average rate of 5% per year. In the absence of a satisfactory permanent storage solution, there are concerns about the accumulation of this waste.

In 2008, the trend of reducing annual quantities of deposited waste continued both in landfills that are part of public infrastructure as well in landfills operated by the industry. In 2008, 835.3 thousand tonnes of waste were deposited on landfills belonging to public infrastructure and 207.8 thousand tonnes were deposited on landfills operated by industry.

Since 2004, the share of collected waste oils in relation to the quantity of oils sold grew from 15% to 30% in 2007, which is the target figure. In recent years, the share of recovered or incinerated waste oils compared to deposited oils is also increasing, which shows that this waste is used as additional energy-generating product. According to 2004 data, 4145 tonnes of waste oils were recovered, and 134 tonnes deposited.

The collected quantities of health-care waste increased after the adoption of the regulation governing this waste. Collected quantities of waste medicines are also expected to increase, since collection in pharmacies was introduced at the end of 2009.

The majority of waste edible oil is exported to other EU Member States for recycling into biodiesel. According to the official records of the Environmental Agency of the Republic of Slovenia, there is no industrial biodiesel production from waste edible oils in Slovenia.

Collected quantities of organic kitchen waste more than doubled after the implementation of the regulation, but its management has so far failed to achieve the set objectives. Deficiencies are particularly evident in composting. About 3,000 tonnes of such waste were composted in 2007, but so far only one entity obtained the environmental permit required for this activity.
