The aim of study was demonstration of dependence of produced biogas on batch composition as agricultural waste. Research was conducted in biogas power plant Biogas Adler, which was the first agricultural biogas plant built in Podlaskie province. The analysis showed in analyzed biogas production of biogas from waste from agricultural activity, is a good way of their utilization, while producing heat and electricity. Among the three analyzed substrates the highest efficiency of biogas production is characterized by corn silage and manure. Potato pulp significantly reduces the efficiency of biogas production. Independently of the composition and quality of substrates, to produce 1 MWh of the biogas plant consumes approx. 457 m³ of biogas.
