Abstract: This paper presents the results of a study of biogas from the anaerobic digestion (AD) process of municipal sewage sludge (SS) under 43–48oC temperature conditions, using the example of a wastewater treatment plant (WWTP) in Tarnów (Poland). In the case in question, the AD of SS is preceded by a 165oC thermal hydrolysis process (THP) using Cambi THP® technology. The study of biogas concerned the basic parameters: temperature, relative humidity, content of CH4, CO2, O2, H2, N2, H2S, CO.
