Selective Collection and Management of Biowaste from the Municipal Sector in Poland: A Review

Municipal waste management is an important aspect in the context of the environmental protection of any country. Biowaste is the dominant stream among all municipal waste in Poland (32.4% in 2020). It can be processed through recycling and recovery processes. It is also possible to dispose of it, although according to the waste hierarchy, such action should be the last option. For biowaste to be recycled, e.g., through anaerobic digestion or composting, it must have suitable properties to be processed through the processes mentioned above. This study aims to discuss the selective collection and management of biowaste from Poland’s municipal sector and identify limiting factors. The paper also indicates selected aspects of possible changes in the waste management sector, considering the role of society and waste management companies. The factors limiting the collection and further use of biowaste from the municipal sector in Poland can be divided into economic, social, technical, and technological. This article refers to the situation in Poland, but some problems occur analogously in other countries. This is because the barriers limiting the selective collection and management of biowaste in many countries are similar and differ mainly in the degree of intensity and the scope they cover. Given the increasingly stringent requirements for waste management, measures must be taken to achieve the legally required levels of recycling of biowaste and to recycle it as well as possible. The development of installations for biological waste management will be crucial.
