Digester plants are constructed of a 55-gallon plastic drum laid horizontally at 151F, plumbed with an inlet, and two outlets for wasting out light and heavy solids. The digests are all insulated temperatures maintained at approximately 1001F. Surface to volume ratio for the fixed-film digester was approximately 45 m³ whereas the same ratio for the control was roughly 9 m³.Fed material was agitated and screened through a 1.5” 2.5” mesh to remove large solid particles over 1.5”. The loading rate was determined by measuring a set quantity of fresh vegetable waste loaded daily into individual tanks, indicated by gradually on floating depth indicators. Biogas production, using a water displacement device designed and carbon dioxide content, recorded daily. Biomethanation is a feasible and effective method of treatment of vegetable waste generated. Vegetable wastes are solid organic waste having high calorific value and nutritive value to microbes that's why the efficiency of methane production be increased by higher order [20]. The waste causes health hazards,and also a risk of epidemic.
