In consequence, decentralised composting can constitute a fundamental form of bio-waste management in 20 out of the 28 gminas of the Łódź Agglomeration. The results obtained from the research facilitate the implementation and wider utilisation of decentralised composting, as an important element of the transition to a circular economy, where bio-waste is concerned.
