On 1 January 2022 new fees for municipal waste management in ACR+ member Warsaw came into force. The rates are now of PLN 85 (EUR 18.74) for a multi-unit household and PLN 107 (EUR 23.59) for a single-family household. The latter amount can be reduced by PLN 9 (EUR 1.98) if bio-waste is composted in a household composter. However, for residents who, contrary to the legal obligation, do not separate waste or do it incorrectly, the waste disposal fees will be doubled. Due to recent changes, property owners and managers must submit a new declaration.
