 abstract={The article reviews selected systems and technological variants of biogas production. Biogas installations and methods of biogas production were characterized in terms of control and measurement. The required technical and technological criteria for biogas production and treatment were indicated. The conditions of biorefining in the context of the generation of new products were analysed. Based on the amount of manure produced in pig production, the potential of biogas production in Poland was indicated based on the visualization of the biogas production potential by poviats in Poland. The substrate in the form of slurry, manure and other agricultural waste for the production of agricultural biogas in Poland was analysed quantitatively. The economic aspects in the agricultural biogas plant sector were revealed, indicating the operation of the economies of scale for this industry sector. An example of a pilot biogas production for anaerobic digestion using pig slurry is presented. The paper presents pre-liminary results of experimental studies on the course of changes in the biogas volume flow for the average daily production of agricultural biogas and the qualitative composition of agricultural biogas produced from pig slurry. The results of the measurements show a clear influence of the hydrodynamic mixing system of the substrate for the evaluation of the biogas flow through the adhesive bed in the context of agricultural biogas production in the range (1–14) m3 d–1.},
