The increasing demand for clean, affordable, and sustainable energy has intensified the need for viable alternatives to conventional fossil fuels, particularly for domestic cooking applications in developing countries. This study focuses on the design and fabrication of a domestic biogas plant for cooking, utilizing biodegradable household waste and animal dung as feedstock for biogas production through anaerobic digestion. The system provides a sustainable solution to energy scarcity and improper waste disposal in rural and semi-urban communities. The biogas plant was designed using standard engineering principles, considering parameters such as gas yield, hydraulic retention time, substrate composition, temperature, and digester volume. Locally available materials were used in the construction of the system to ensure cost-effectiveness and ease of maintenance. Major components include the digester tank, gas holder, inlet and outlet pipes, and a biogas burner system for cooking applications. The result shows that methane-rich biogas was produced within 7–10 days after initial loading, indicating effective anaerobic digestion. The generated biogas was successfully utilized for cooking, demonstrating stable combustion and practical applicability for domestic use. The study highlights the potential of biogas technology in reducing dependence on traditional fuels such as firewood and kerosene, while promoting sustainable waste management. The developed system offers an efficient and affordable solution for household cooking energy, with potential for wider adoption in developing regions.
