Possibilities of Producing Agricultural Biogas from Animal Manure in Poland

Biogas production from agricultural residues is a promising solution for renewable energy production, improved waste management, and beneficial impact on climate change mitigation. The aim of this study is to assess the actual use and theoretical potential of agricultural biogas produced from animal manure in Poland at the local level. The potential and actual use of agricultural biogas are presented regionally (16 voivodeships) and locally (314 districts). The theoretical potential of agricultural biogas was estimated based on data from the Agricultural Census conducted by the Central Statistical Office in Poland in 2020. Actual biogas production is based on data from the Register of Agricultural Biogas Producers maintained by the National Support Center for Agriculture. The study shows that Poland is only tapping into the existing potential for agricultural biogas production to a limited extent. Furthermore, both actual agricultural biogas production and the identified theoretical potential vary spatially (greater potential in the northern part of the country, significantly lower in the southern part). This situation is attributed to existing barriers that hinder the utilization of existing potential. Therefore, it is crucial to seek new solutions to reduce existing barriers of an organizational, legal, technical, economic, environmental, spatial, and social nature.
