Abstract
- In an urban context, municipal mixed sludge (MMS) and fruit and vegetable waste (FVW) are becoming the major organic solid wastes in human society. Thus, anaerobic digestion as a low carbon energy strategy to minimize their environmental polluting risk was studied. To overcome the drawbacks of anaerobic digestion of MMS, an alternative approach is proposed, involving the addition of increasing proportions of mango peel pulp (MPP) as a co-substrate. Different ratios of MMS:MPP (v:v) were studied: 80:20 (T1), 70:30 (T2), 60:40 (T3). The increase in the organic loading rate was well incorporated by the reactor's biomass activity, and it had no negative effects on the reactor stability and performance operational parameters. Results indicated that the addition of MPP had a beneficial effect on specific methane production, where the highest value was registered in T2 (0.47 L CH4/g VS added), with a 1.8-fold increase in this operational parameter. Moreover, bioenergy recovery within the same trial followed the same profile, representing a two-fold increment.
