and 113.2 L CH4/kgvs (72 L CH4/kg-dry waste) were generated in C1
and C2, respectively. The results were comparable with the previous
studies listed in Table 3. Methane generation was reported
to range from 20 to 110 L CH4/kg-dry waste. The variation of
methane generation mainly resulted from the differences of waste
compositions and reactor operations.
