AbstractAnaerobic degradation (AD) of municipal solid waste (MSW) depends on the moisture and nutrient distribution within thebioreactor; these factors are affected by leachate recirculation. In this work, the effects of leachate recirculation of 15 to 120 byvolume percentage (%V) on AD were studied. The ojectives of this study are as follows: a) to determine which recirculation rateprovides the best conditions for accelerated anaerobic degradation (AD) and b) to determine the optimal range of r...

The present study deals with the production of biogas from post-harvest wastes of pineapple such as peels, leaves, mixture of peels and leaves with the two different types of inoculum viz., Cow Manure (CM) and Novel microbial Consortia (NC). The results between the two types of inoculum were compared to find out their efficiency. Among the different substrate-inoculum combinations, the biogas production potential was evaluated which resulted that NC was more efficient compared to CM. All assays ...

Large amounts of spent coffee grounds (SCG) are currently available all over the world due to the enormous increase in coffee consumption. This increase has in turn to be related to the even greater diffusion of coffee vending machines. The aim of this study was to evaluate the biomethanation potential (BMP) of SCG alone or in co-digestion with pig slurry (PS). Pig slurry was chosen because it is frequently utilized as feedstock for biogas production from agricultural waste. The raw material was...
