PB - Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego N2 - The paper presents results of research on changes in the physicochemical properties during co-fermentation process of coke and municipal sludges. The process was carried out at 37°C for 20 days, for the three mixtures of sludge. The mixture of raw sludge and excessive sludge inoculated with fermented sludge was a control sample. N2 - The other two samples are mixtures with the addition of coke sludge in the amount of 5% (B1) and 15% (B2). The degree of decomposition of organic matter was 28% for control sludges and 27% and 24%, respectively, for sludge B1 and B2. The largest summary production of biogas was obtained for the control sludges (5727 cm3/dm3). N2 - In the reactor, to which a 5% of coke sludge was introduced the total production was lower and amounted 5126 c3/dm3. In the case, when a 15% of coke sludge was introduced total biogas production amounted 3653 cm3/dm3.
