Key statistics

Compared to the 3rd quarter of 2022:

  • Almost 40% more waste collected in total.
  • 44% more construction waste collected.
  • A tenth less mixed municipal waste collected.
  • Almost five times more bulky waste collected.
  • A quarter more municipal waste landfilled.

Significantly more construction waste collected and backfilled

More than 3.5 million tonnes of waste were collected in total, which is a million tonnes more than in the same period last year. The growth was due to the increase in the amount of collected construction waste, which was 900,000 tonnes and accounted for 84% of total waste collected.

Compared to the 3rd quarter of last year, roughly the same amount of waste was planned for recycling, around 660,000 tonnes, of which 15% in composting and biogas plants. The amount of waste intended for incineration with energy recovery decreased by more than a third to 21,000 tonnes. The amount of waste planned to be backfilled more than doubled, which is mainly the result of more construction waste collected as it is mostly backfilled. 46,000 tonnes of waste, of which 44% was municipal waste, was planned for disposal in landfills.

Significant increase in bulky waste

The amount of municipal waste (268,000 tonnes) was slightly larger (by 2%) than in the same period last year, although the amount of mixed municipal waste decreased by a tenth. The highest growth - by almost five times - was recorded with bulky waste, which is mainly a result of the severe floods in early August. Bulky waste accounted for almost 17% of all separately collected municipal waste, while the share in the same period last year was 4%. Only biodegradable waste (almost a quarter) and paper and cardboard (almost a fifth) accounted for a larger share of separately collected municipal waste. In total, 78% of municipal waste was collected separately.
