Biogas Production from Wheat Straw Co-Digested With Poultry and Goat Manure

Abstract:

Biogas production using anaerobic digestion of organic waste materials provides an alternative environmentally friendly renewable energy. In this study, the production of biogas from co-digestion of wheat straw with poultry and goat manure was evaluated in seven treatment under mesophilic condition 380C for30 days of retention time, using a batch digester in Botanical and Central Laboratories of Haramaya University. Total solids, volatile solids, percent moisture content, pH, organic carbon, organic nitrogen and carbon to nitrogen ratio were measured following standard methods for all substrates before and after digestion. The results indicates all measured physicochemical parameters of each substrate was significantly (P
