Abstract
Bioreactor-special device is used for biogas production from various organic materials under anaerobicconditions. In this research, a batch bioreactor with a mechanical mixer was used for biogas production fromsewage sludge and chicken manure bioloadings. The process of anaerobic digestion was mesophilic (35oC). Producedbiogas was stored in a gasholder and the concentration of its components was measured with INCA 4000 biogasanalyser. Also, a specific additive (pine wood biochar) was applied to prepare bioloadings. The application of woodbiochar in bioloading increases the CH4 concentration in the produced gas by 6-7%. The highest concentrations ofCH4 were found in biogas produced during the decomposition of sewage sludge bioloadings. The maximum CH4 reached 77.4%. Studies have shown that the application of biochar in bioloadingsalso reduces average CO2 and H2S concentrations in biogas.
