The spent coffee grounds (SCG) were acidogenic fermented and it used as a co-feedstock in the anaerobic co-digestion process. After mixing sewage sludge and acidogenic fermented SCG in a ratio of 7:3 (SF2), the effect on biogas production was observed. The cumulative biogas production during 30-day digestion time was determined 705.28 mL for SF1 (only sewage sludge) and 1891.98 mL for SF2, indicating that SF2 produced about 2.68 fold more cumulative biogas. The methane content in produced biogas was determined 62-65% and 70-73% for SF1 and SF2, respectively. Moreover, the specific biogas production was found to be 0.35 ± 0.11 mL/kg·TS and 0.43 ± 0.13 mL/kg·VS for SF1 and 0.64 ± 0.15 mL/kg·TS and 0.81 ± 0.16 mL/kg·VS for SF2. In addition, the calculated energy production was 2.76 kWh for SF1 and 5.82 kWh for SF2, indicating about 2.1 fold higher energy production than that of SF1. Finally, the co-digestion performance index was 1.69 for SF2, so it was confirmed that the synergistic effect for biogas production was high when anaerobic co-digestion using FSCG as a co-feedstock.
