Abstract:

Energy is one of the most important factors for human development and to global economic growth. Biogas is a mixture of gases, mainly methane and carbon dioxide, resulting from anaerobic digestion of organic matter. In this study, biogas production from co-digestion of cow manure (CM) and avocado fruit peel (AF) waste in five mix ratios (100%CM, 60%CM:40%AF, 50%CM:50%AF, 40%CM:60%AF and 100%AF) were evaluated under mesophilic condition at 38ºC using a batch mode digester in Microbiology Laboratory of Haramaya University. In all the treatments, physico-chemical parameters such as pH, total solid, volatile solid, organic carbon, total nitrogen and carbon to nitrogen ratio were measured all substrates before and after anaerobic digestion. The results showed that all measured physico-chemical parameters of each substrate significantly (P
