Rational waste management is an essential element in the process of transitioning the linear economy into a circular model. Those actions that are taken to achieve better results in this area are important for regional and local development as well as for the implementation of sustainable development goals. This article presents the requirements and rules for the functioning of waste management in Poland. Taking the structure of the system into account, the functioning of waste management in the municipality of Krakow was analyzed. Particular attention was paid to the problem of municipal waste segregation by the inhabitants of Krakow. As part of our own research, surveys were conducted among the employees of the Municipal Cleaning Company LLC (Miejskie Przedsiębiorstwo Oczyszczania w Krakowie – MPO Sp. z o.o.), which showed the scale of the deficiencies. The results of the research were helpful in proposing actions to increase the effectiveness of the wastesegregation system in Krakow.

In Poland, the potential for biogas production is high. It is an important source of renewable energy and contributes to reducing methane emissions (a greenhouse gas). In this article, the implementation of an agri-gas plant-construction program was evaluated in individual voivodeships based on materials from the National Agricultural Advisory Center (KOWR), the literature, and statistical data. Based on the collected data, it was concluded that the most meaningful factors for the successful development of Polish agricultural biogas plants were biogas-production technology, substrate availability, energy prices from renewable energy sources, waste-disposal costs, the population density in a commune, and the allocation of places in local spatial-development plans. The DEMATEL technique was used to identify the key developmental factors. The results of the study provide useful information for both governments and local authorities in their searches for effective ways to drive the sector’s development.
