Abstract: This study investigated the potential of overripe tomato waste as a sustainable bioenergy source through the use of a Microbial Fuel Cell (MFC) system for electricity generation. An experimental quantitative research design was employed to evaluate the electrical performance of an overripe tomato-based MFC in comparison with a mud-based MFC used as a positive control. Key parameters measured included voltage output, current production, and power density, along with microbial activity indicators such as bacterial growth rate, electron transfer efficiency, and biofilm formation. A total of ten trials were conducted under controlled conditions to ensure data reliability and consistency. Statistical analyses, including frequency distribution, mean computation, and independent sample t-tests at a 0.05 level of significance, were used to determine differences in electricity generation between substrates. Results of the study aim to demonstrate the feasibility of converting organic tomato waste into bioelectricity, supporting sustainable energy development, waste reduction, and low-cost renewable energy solutions, particularly for urban communities such as Davao City.
