A few facts about municipal waste management:

The municipal waste sorting rate for 2021 was 41,33%
    Collection and transportation for the purpose of recovery and disposal of municipal waste is provided by Odvoz a likvidácia odpadkov (OLO); this is a joint-stock company whose sole shareholder is the city.
    Incinerable and otherwise materially unusable waste is used to generate energy and is thermally disposed of in the waste incineration plant in Vlčie hrdlo.
    The plant was built between 1974 and 1977 as the first incineration plant in post-war Czechoslovakia. Following improvements that were made in 2002 (waste disposal and flue gas cleaning technologies), the plant complies with the European emission limits for pollutants.
    Over the expected twenty-five years of operation after these improvements, the incineration plant is expected to incinerate an additional three million tonnes of waste. The maximum capacity is 135,000 tonnes of waste per year.
