The quantity of total waste generated, which was declining during the crisis, has been rising in the last few years. In 2015 approximately 5.2 million tonnes of various types of waste was generated in Slovenia, around 10% more than one year previously and 16% more than in 2012, a year when the recorded quantity was also relatively low owing to a change in methodology. Waste from production and service activities, which accounts for 80% of total waste, had been rising more slowly, except last year when it increased slightly more. The majority of waste, around 90%, is generated in four sectors: (i) manufacturing; (ii) construction; (iii) electricity, gas and steam supply; and (iv) water supply, sewerage, waste management and remediation activities. The largest share is accounted for by construction waste, which has a high specific weight. The remaining fifth is municipal waste, i.e. waste from households and other waste of similar origin managed by the providers of mandatory municipal public services for environmental protection. The quantity of this waste increased by around one-quarter in 2012–2015. Particularly problematic is hazardous waste, where chemical compounds and other chemical waste predominate; it accounts for around 3% of total waste generated and is increasing in the long term.
Waste recovery is increasing faster than waste generation and the quantities of landfilled waste are falling. The total quantity of waste recovered in 2015 amounted to around 6.9 million tonnes, 13% more than in 2014 and almost twice as much as a decade before. However, as the share of backfilling or pre-treatment, which had been lowest at the beginning of the crisis, increases, the actual amount recovered was more than half lower. Recycling, a very desirable form of recovery from an environmental perspective, rose slightly for the second consecutive year, but it was still significantly lower than during the crisis. In the period after the crisis, its share more than halved, to 42% of total recovery. Landfilling, which is the least favoured option in the waste management hierarchy, continues to be successfully reduced. The quantity of landfilled waste had also been highest at the onset of the crisis, but following a steep decline, this waste accounted for only 4% of the total amount processed in 2015. The share of landfilled municipal waste also decreased further, as more than two-thirds of municipal waste is already collected separately and as residual mixed municipal waste must be treated before going to landfill; it totalled 23%, which is slightly better than the EU average.
In the area of municipal waste, Slovenia performs better than the EU as a whole. Despite the increase in 2014 and 2015, the quantity of municipal waste generated per person is still lower than the EU average (in 2015 by 28 kg or around 6%). Waste-management structure is also better than in the EU generally, as a larger share of municipal waste is recycled and a smaller share landfilled. Meanwhile, as many as six EU Member States have already reduced their shares of landfilled municipal waste to below 3% of total waste generated.
