Rationalisation of costs in the collection, segregation and transport of municipal wasteZając, Paweł (Avtor) Bajor, Ivona (Avtor) Obrecht, Matevž (Avtor) Ejdys, Stanisław (Avtor) wastemixedsortingfeemanagementThe article contains answers to three "why" questions: - why the waste management system still does not bring the expected results, and the Polish state is one of the lowest-ranking in the European score regarding the amount of segregated waste; - why the sale of selected secondary raw materials and their material reuse in production processes do not cover the costs related to waste management; - why it does not bring additional profits. The article is based on research conducted in Wroclaw from 1998 to 2018. There is a cost model that can be adapted to similar cases. The article deals with removing organisational and/or technical reasons causing the stagnation of selective waste collection.20232024-02-16 13:00:32Članek v reviji87084UDK: 519.8:628.4COBISS_ID: 185807107DOI: 10.54740/ros.2023.033ISSN pri članku: 2720-7501sl
