Batch experiments were conducted to study the impact of the use of a mixed inoculum on the methane yield for wet, mesophilic, discontinuous anaerobic digestion of food waste. Three different inocula were used: cow rumen, AD (anerobic digestion) sludge and UASB (Upflow anaerobic sludge blanket) sludge. The results indicated that the use of a mixed inoculum does not lead to any improvements in the methane yield. |
