4. Conclusions
The study successful demonstrated that fermentation process can be used to produce methane from
fresh banana peel and reduce the organic waste in the peel at the same time. The optimum condition of
the process was achieved. However, methane yield obtained in this study (77 L kg-1 dry weight) was
lower than that from the previous studies (190 to 266 L kg-1 dry weight). Results suggested that size of
banana peel affected the bacteria utilization of the substrate for produce methane. Size reduction of raw
material and fungal pretreatment might improve the methane yield from banana peel fermentation in the
future work.
