Co-Digestion of Ethiopian Food Waste with Cow Dung for Biogas Production

Alemayehu Gashaw, Abile Teshita

Abstract


Now a day biogas production is one of the most promising renewable energy sources in Ethiopia. Anaerobic digestion is one of the effective ways of generating biogas. It is also a reliable method for treating food wastes such as cafeteria wastes, vegetable wastes etc. and cow dung and the digested slurry can be used as fertilizer to enhance the fertility of the soil. Co-digestion of food waste with cow dung or other feed stocks with low carbon content can improve process stability and methane production. Anaerobic co-digestion of food waste with cow dung is needed to enhance biogas production and very useful to treat these wastes. This review paper looks at the possibility of producing biogas from co-digestion of food waste with cow manure by optimizing the parameters that affect biogas
