Large amounts of vinegar residue generated in the vinegar brewing process have been a severe threat to the environment. In this study, solid-state anaerobic digestion has been applied for sensible utilization of vinegar residue. Besides, alkali pretreatments, microwave pretreatment, and their combinations were introduced to enhance the degradation of vinegar residue in solid-state anaerobic digestion. Results showed alkaline hydrogen peroxide and microwave co-pretreatment performed better in regard to the cumulative methane yield, showing a remarkable increase of 34.6% (p |
