In the master's thesis, we have investigated organization of public services, which, being obligatory, are carried out in the field of municipal waste management and deal with collection and transportation of municipal waste. In spite of the efforts and the introduction of the European legislation into the national acquis, municipal waste management is still considered to be a relatively poorly regulated area, and despite the improvement of results in previous years, planning and reaching targets still lag behind the best EU Member States. An excessive number of public services, i.e. more than 60 in Slovenia, contributes to additional fragmentation and prevents efficient, rational and goal-oriented targeting. What is more, additional problems are caused by different forms of organization as well as the size of individual public services. The aim of the master's thesis is thus to provide answers to the questions, which shall present a comprehensive overview of public service regime, introduce key features of specific forms of organization, and verify efficiency and performance of public services. The hypothesis is that public services operating in a larger area perform better in comparison with smaller forms of organization. In addition, we also presume that public services that act as private companies achieve better results. The master's thesis consists of three key parts, i.e. methodological definition, theoretical elements, and own analyses with conclusion, where key findings of the master's thesis are described.
