At present world is moving towards renewable energy resources, especially biomass. The fruit and vegetable waste (FVW) is an essential component of municipal solid waste that mostly comes from households and wholesale markets. The FVW is biodegradable in nature and there is no proper method to manage this type of important organic waste. This study examines the composition and characteristics of fruit and vegetable waste for suitable utilization in anaerobic digestion process to produce methane yield. The physical composition of FVW comprises of 69.59% of vegetable waste and 30.41% of fruit waste. Initially, the characteristics of FVW were analyzed for pH, total solids, and volatile solids which were 5.7, 13% and 87% respectively. The Biochemical Methane Potential (BMP) assays were performed in 500-mL borosilicate glass reactors and operated at 37 °C±1. The total alkalinity and volatile fatty acids that affect methane production in the anaerobic digestion process were analyzed at the end of batch reactors to monitor the volatile fatty acids to alkalinity ratio. The pH was found in the range of 6.6-7.1 in all reactors which is favourable for methanogens bacteria in digestion process. The specific methane yield of R3 was 212 Nml/g VS which is higher than specific methane yield of R1 and R2. The findings of this study suggests that more buffalo dung than fruit and vegetable waste produces more methane production in batch assays. [ABSTRACT FROM AUTHOR] |
