In 2023, the preparation for re-use and recycling rate—calculated using Methodology 4 and excluding construction and demolition (C&D) waste from household sources—stood at 50.8%, thus exceeding the 50% target set for 2020.

The indicator measures the amount of special waste sent abroad for recovery and disposal. In 2022, the total exported special waste amounted to approximately 4.9 million tons, of which 3.4 million tons were non-hazardous waste (70% of the total) and 1.5 million tons were hazardous waste (30% of the total). The largest quantities of waste were sent to Germany and Austria, with 977,000 tons and 600,000 tons, respectively. 

The indicator measures the amount of waste sent for biological treatment, specifically composting, integrated anaerobic/aerobic treatment, and anaerobic digestion. In 2022, the total amount of waste recovered through biological treatment processes (approximately 8.4 million tons) showed no significant variation, with a slight increase of 47,000 tons (+0.6%) compared to 2021. However, the share of organic waste, which decreased from about 6.8 million tons to approximately 6.7 million tons (79.6% of the total treated), saw a decline of around 132,000 tons (-1.9%), mainly due to a lower contribution of biodegradable waste from garden and park maintenance.
