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 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.

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.

In Slovenia, alluvial aquifers present 60 % of the drinking water sources, and karst-fractured aquifers present 40 %. Due to populated areas and intensive agricultural production, alluvial aquifers are exposed to greater risks of pollution with nitrates.
