Biogas is an increasingly important renewable energy resource in a world facing environmental challenges and the urgent need for sustainable solutions. Produced through the anaerobic decomposition of organic materials, biogas offers an efficient means of valorising organic waste. The production process yields a gas mixture, primarily methane and carbon dioxide, that can be converted into electricity, heat, or fuel, thereby contributing to the reduction of greenhouse gas emissions. Moreover, it supports a sustainable resource cycle, making this technology a highly promising solution for the future of green energy. This study presents a comparative analysis of the operational performance of the Moara-Suceava biogas plant when using agricultural residual biomass (corn and animal waste) versus organic waste from the food industry. The results indicate that, although larger quantities of raw material are required to produce the same volumetric amount of biogas from food industry waste, the latter yields higher lower heating values (5.81–6.20 kWh/Nm³) compared to agricultural residual biomass (4.50–4.91 kWh/Nm³).
