The growing demand for sustainable energy highlights the need to utilize underexploited resources, such as agricultural residues, to meet global energy challenges. In Colombia, significant quantities of biomass, including sugarcane bagasse and coffee husks, remain untapped despite their renewable energy potential. This study explores the feasibility of transforming agricultural residues into clean energy through biodigestion, to support national energy and sustainability goals. Using a phased methodology that integrates geographic information systems (GIS) and multi-criteria decision-making, the study identifies and evaluates biomass availability, energy potential, and the most suitable transformation technologies. Key findings highlight Malambo's potential for rural electrification through biodigestion, showcasing significant environmental and economic benefits. Biodigestion was selected as the optimal technology, offering higher efficiency and sustainability compared to alternatives like pyrolysis or direct combustion. This work stands out by demonstrating a scalable and systematic approach to utilizing agricultural residues for rural energy generation. It provides actionable insights into the integration of residual biomass into Colombia's energy matrix, paving the way for reduced fossil fuel dependence, improved rural electrification, and enhanced local development.
