More waste in the last quarter of the year

The biggest change occurred in the amount of mineral waste, as it more than doubled compared to the previous quarter (from 2 to 4.4 million tonnes). It is mainly soil and stones that are the result of excavation at construction sites. Accordingly, the amount of waste planned for backfilling also increased significantly. The reason for this is the receipt of completed record sheets on waste at the end of the year, part of which was already collected, treated or disposed in previous quarters.

The collected amount of municipal waste was also higher (297,000 tonnes), a part of which was already collected in previous quarters, but confirmed with record sheets only in the 4th quarter. Thus, in the last quarter, compared to the average of the previous quarters of the observed year, the amount of mixed municipal waste collected by public waste removal scheme increased by 65% (to 109,000 tonnes), and the share of municipal waste intended for disposal at landfills increased by 66% ( to 24,000 tonnes). Due to higher amounts of collected mixed municipal waste, the share of separately collected municipal waste fell to 63.3%.

In 2022, most mineral waste collected so far

In total, more than 12.3 million tonnes of all types of waste were collected last year, which is 30% more than the year before. The collected mineral waste increased by two-thirds to around 10 million tonnes. 1.07 million tonnes of municipal waste were collected (2% less than in 2021) or 507 kg per person, of which 71.3% was collected separately. 125,000 tonnes of hazardous waste was collected, which is 8% less than the year before. About 10 million tonnes of waste was planned for treatment by final procedures, of which almost 7 million tonnes were for backfilling and almost 3 million tonnes were for recycling. The rest (approximately 120,000 tonnes) was incinerated with energy recovery. Around 403,000 tonnes of waste was disposed by final treatment. 173,000 tonnes was landfilled, of which more than 39% was municipal.

The final official data for 2022 will be published at the end of September 2023.
