This thesis presents a comprehensive framework for identifying optimal locations for crop waste-based biodigester installations in rural Ethiopia, with a focus on the Buno Bedele zone. Applying a clustering algorithm and Geospatial Information System (GIS) analysis, the research aims to maximize energy production while minimizing logistical challenges associated with biodigester implementation. Through an iterative process of refining Center of Energy Demand (COD) locations and adjusting parameters such as energy demand radii, the framework demonstrates how to enhance the suitability of biodigester placements. Key findings indicate that a 2 km energy demand radius for 100 CODs oers a balanced solution, providing comprehensive coverage and ecient use of crop waste resources. Moreover, increasing the number of CODs to 200 further improves coverage, presenting opportunities for expanded deployment. Locating biodigesters based on energy demand and crop waste availability, can reduce the communities’ reliance on traditional biomass fuels, leading to improved indoor air quality and reduced deforestation. Additionally, the utilization of bio-slurry fertilizer produced by biodigesters oers added benefits by enhancing soil fertility and agricultural productivity, contributing to food security and sustainable development. By tailoring both the sizes and locations of biodigesters to the specific needs of rural Ethiopian communities, this framework can help to optimize resource utilization and enhance the overall eectiveness of the National Biogas Programme of Ethiopia (NBPE). The findings from this study contribute to the advancement of sustainable energy solutions in rural Ethiopia and provide valuable insights for biodigester deployment strategies in similar contexts worldwide.
