The production and use of biogas can play a key role in the transition to a low-emission and circular economy. Animal waste is an available, local substrate for biogas plants, although it is used less frequently than plant waste. Therefore, the main aim of this research is to assess the potential of animal biomass and the possibility of producing biogas from it to meet energy needs in EU countries. The potential was estimated for the 27 European Union Member States. Data comes from the Statistical Office of the European Union from 2024. Biomass volumes and the potential for biogas production were estimated using formulas available in the literature. Analyses indicate that European Union countries have significant potential for biogas production from existing biomass from animal waste. Even in countries with relatively high current production, there is significant potential for the production and use of larger quantities of biogas. To achieve climate goals, besides large investments, micro-biogas plants are gaining importance. Small installations may prove to be a solution for countries with quite small and dispersed animal production. Widespread utilization of the potential of biomass from animal waste requires institutional support as well as dissemination of knowledge among various stakeholder groups.
