Abstract
This study is conducted to investigate the effects of anaerobic treatments of swine manure slurry alone and combination of livestock manure slurry and fruit pomace on biogas production. Anaerobic co-digestion was evaluated in mesophilic tank reactors for 96 day-incubation period. The organic matter loading of anaerobic digestion was 1 kg of volatile solids(VS) per $1m^3{\cdot}day$. The highest methane production was achieved from the combination of swine manure slury and mandarin pomace(70:30) treatment, whereas the lowest daily and cumulative methane yields was observed in swine manure slurry alone treatment. More than two-fold increase in bio-gas and methane production was obtained by combination of livestock manure slurry and mandarin pomace treatment, compared to the swine manure slurry alone treatment. The co-digestion of livestock manure and fruits pomace has advantages to enhance the production of methane gas, compared to digestion of swine manure slurry alone.
