The environmental impacts of conventional energy sources and the importance given to renewable energy technologies lead to the use of bio-gas in a number of applications such as power gen-eration, heating and refrigeration. The quantity and quality of biogas depend on the ingredients and their compositions in the biowaste. In this present work, analytical and experimental studies have been con-ducted to predict the generation of methane from the biowastes produced in an educational institution where the availability of biowaste is not uniform throughout an academic year. The Anaerobic Diges-tion Model 1 (ADM1) is used for analytical studies, and four portable anaerobic digesters, manufactured by fibre-reinforced plastic, are used in the experi-mental investigation. The observations show that the biogas produced from the wastes available in the educational institution could substitute 30 to 35% of the conventional cooking energy used inside the campus, and average methane contents in the biogas produced from cow dung, rice waste, mixed rice waste and vegetable waste are 58.01 %, 51.96 %, 54.85 %, and 52.28 % respectively. It is also ob-served that the yield and the quality of biogas are influenced by the uniformity in organic loading.
