The article presents the results of biogas production from municipal and agricultural waste. The mesophilic digestion of feedstocks was evaluated. Fermentation process was performed according to the DIN 38414-S8. Five types of agricultural waste were used for the research: 100% maize silage, 25% apple pomace – 75% maize silage, 50% apple pomace – 50% maize silage, 75% apple pomace – 25% maize silage and under – size fraction of municipal waste from the sorting drum. Fermentation of waste was carried out for 30 days. In the produced biogas, there were measured the content of: CH4, CO2, O2 and the total yield of biogas. The combination of different groups of waste in the fermentation process causes a higher efficiency of biogas production. Additionally thermal analysis (TG, DSC) of biogas digestate were conducted. Due to the impurities present in the biogas digestate derived from municipal waste, it becomes impossible to use it as fertilizer in agriculture.
