Abstract
This paper presents mesophilic anaerobic digestion (AD) of organic fraction of municipal solid waste (OFMSW), biowaste (BW), sewage sludge (SS), and co-digestion of BW and SS. Average methane yields of 386 ± 54, 385 ± 82, 198 ± 14, and 318 ± 59 L CH4/kg volatile solids (VS) were obtained for OFMSW, BW, SS, and co-digestion of BW and SS respectively in reactor experiment with organic loading rate (OLR) of 1 and 2 kg VS / m3 d. Average methane yield of SS was increased by 61% as a result of co-digestion with BW.
Methane potentials of 603, 534, and 369 L CH4/kg VS were obtained for BW, OFMSW and SS respectively in batch experiments at 35 °C. Methane potential of source-separated BW was 12% higher than methane yield observed for mechanically treated OFMSW, which can be interpreted as a positive effect of source-separation on methane potential.
