Comparative Study of the Potential of Dog Waste for Biogas Production

E.C. Okoroigwe, C.N. Ibeto and C.G. Okpara
The potential of dog waste to produce biogas and/or enhance the biogas productivity of some other animal and plant wastes was investigated. Two waste combinations of dog waste with field grass (DG), dog waste with cow dung (DC) and one single waste type of dog waste alone (D), were used in the investigations for comparing the potential of dog waste for biogas production. The results showed that D (7 kg), DG (10 kg), and DC (10 kg) were capable of producing a total of 178 L, 218 L and 296.7 L of biogas, respectively in a 50 L digester in 50 days. Hence, dog waste can be a source of biogas and a source of catalyst for prolonging the retention time of other waste samples such as field grass and cow dung. The result of the proximate and microbial analyses reveals that dog waste has high potential for biogas production that even though its quantity may be small, it is a good blend for other waste types such as field grass and cow dung.
