Proximate and Chemical Analyses of Selected Agricultural Wastes Used for Biogas Production

Abstract

Due to the rising cost of fossil oil accompanied with pollution problems associated with petroleum and allied products have led to the search for alternative sources of energy. This research was conducted to determine the proximate and chemical analyses of fresh and spent slurries with a view of determining their suitability for energy production. The samples were analyzed according to standard analytical techniques. The proximate and chemical analyses of the substrates hold promise as a potential biogas source as evidenced by the 4773, 6535, 6684, 3834, 4096 and 6199 kcal/kg for the pumpkin, plantain, banana, spinach, watermelon and synergized mixture respectively. The spent slurry offers promise as an excellent source of plant nutrients since it could serve as a source for bio-fertilizer production
