Laboratory scale semi-continuous stirred tank reactors fed with food waste were used to investigate the effects of trace elements Co, Ni and chelating agent EDTA supplements on the biogas process. It was observed that the addition of Co, Ni and combination of the two elements increased the biogas yield compared to the control reactor by 15.0%, 30.8% and 39.5% respectively. The VFA, pH, methane content and TS content in the digesters were also stabilized. Ni was found to play a more important role in anaerobic digestion of food waste than Co. The combination Co-Ni added reactor performed better than those with individual elements regarding total biogas production and process stability. Addition of EDTA known to improve metal bioavailability showed that Co with EDTA supplement moderately affected the performance compared to Co only reactor, whereas EDTA with Ni addition showed no improvement.Keywords

Mesophilic (37°C) anaerobic co-digestions of rice straw and cow manure were carried out based on different VS ratios (0:1, 1:2, 1:1, 2:1 and 1:0). Results indicated that co-digestion has a better performance than mono-digestion of rice straw; both biogas and methane yield were significantly increased. Biogas yield was 363.33, 402.45, 390.25, 388.50 and 389.33 mL/gVS for RS: CM ratios of 1:0, 2:1, 1:1, 1:2 and 0:1, and the corresponding methane yield was 175.01, 194.91, 185.13, 194.59 and 189.09 mL/gVS, respectively. Average methane content was 48.17%, 48.43%, 47.44%, 50.09% and 48.57%, respectively. No volatile fatty acids and ammonia inhibition was observed in the experiment. The pH values were in the range of 6.8-7.5. By comparing the ratios of actual to theoretical biogas yield (Ya/Ym), it was found that the ratio increased when carbon to nitrogen (C/N) ratio was 15.10-28.85; the further C/N ratio increase led to Ya/Ym decrease. In actual application, the ratio of rice straw to cow manure of 2:1 and HRT of 18 days was recommended.Keywords
