Determinant and Characterization of Biogas Product at Different Agroecological Zones of Ethiopia

Year: 2025

Type: article

Abstract: Biogas production uses microorganisms to degrade organic material in the absence of oxygen to produce CH 4 , CO 2 , and other residual gases. Anaerobic digestion of cattle manure and human feces for biogas production is an important technology in Ethiopia’s National Energy Strategy. Thus, this study aimed to analyze determinants and characteristic composition of biogas product at different agroecological zones in Southern Ethiopia. In this study, biogas plants were categorized based on agroecology, size, age, and design type. A total of 32 biogas plants were included and their gas composition were analyzed using OPTIMA Biogas Analyzer. One-way ANOVA and paired-wise comparison were widely used for data analysis. ANOVA results for CH 4 revealed that agroecology, temperature, and biogas plant design were statistically significant whereas biogas plant size and age of biogas plants were not statistically significant. From this study, the authors concluded that agroecology, biogas plant design, and temperature significantly affect biogas yield quality. Future research needs to focus on seasonal variation of biogas product at different agroecological zones and evaluation of the rural household biogas plants’ performance.
