    Conversion of animal waste to biogas energy to replace traditional fuel and use of the slurry as a fertilizer is the current focus of the national biogas program of Ethiopia (NBPE). However, there are many plant species which could also be probed for their potential of biogas production. This paper presents the experimental results of the anaerobic digestion of Justicia schimperiana (JS) and cow dung each separately and with their various combinations at Addis Ababa University Environmental Science Laboratory. The biomass of JS and cow dung were characterized and then estimation of biogas production and methane content of each treatment, T1 (cow dung alone), T2 (1:1), T3 (2:1), T4 (3:1), T5 (JS alone), T6 and T7 (with digester effluent) was performed using indirect (water displacement) and absorption of CO2 by 10% NaOH methods, respectively. Statistically significance difference (at 0.. Read More»
