ABSTRACT
The potential for producing biogas from agricultural waste generated in tertiary institutions in Anambra State, Nigeria, is examined in this study. Samples of agricultural and food waste were gathered and examined over a four-month period from three campuses that had cafeterias, active livestock, and crop production units. In order to estimate methane yield and evaluate the viability of decentralised biogas systems in institutional settings, the study used biochemical methane potential (BMP) testing in mesophilic conditions. According to the results, the chosen institutions produce more than 5.4 tonnes of biodegradable waste per week, with an average biogas yield of 0.38 m³ CH₄/kg volatile solids (VS). The analysis also shows that up to 25-35% of these campuses’ energy requirements for cooking and heating could be satisfied by decentralised biogas plants. According to technical, economic, and environmental considerations, installing modular anaerobic digesters might cut greenhouse gas emissions by 1200 tonnes CO₂-equivalent year. The findings outline a reproducible framework for sustainable campus energy systems in developing nations.
