Abstract
Anaerobic digestion is the biodegradation of the waste material with the aid of microbes which
thrive in the absence of oxygen. Fruits and vegetable wastes (FVW) are a good substrate with potential to
produce biomethane and are abundantly available. The optimization of biogas production from FVW was
reviewed. A careful consideration when selecting the operating process parameters such as temperature, pH,
hydraulic retention time (HRT), organic loading rate (OLR), inoculum to substrate ration (ISR) , particle size
and nutrients. The following factors can improve the methane yield from FVW: co-digestion, pre-treatment
and digester configuration.
