Abstract: Biogas production is a sustainable and renewable alternative energy source that offers a viable solution to reducing reliance on fossil fuels while addressing waste management challenges. Over recent years, biogas has gained significant acceptance due to its environmental benefits and potential for energy generation. This project focuses on the production of biogas using cow dung and pineapple waste as feedstock. A total of 5kg each of cow dung and pineapple waste were prepared and mixed with an equal volume of water to form a homogenous slurry. The mixture was loaded into a bio-digester fabricated within the department and allowed ferment anaerobically for 20 days under controlled conditions at an ambient temperature of 27°C. The biogas produced was analyzed using Gas Chromatography (GC), revealing a methane content of 80.44% and carbon dioxide content of 19.56%. The high methane concentration demonstrates the effectiveness of cow dung and pineapple waste as suitable substrates for biogas production. This study highlights the potential for utilizing agricultural and organic waste to generate clean energy, providing a sustainable method of handling waste management and energy sustainability. Further optimization of variables like temperature, retention duration, and substrate ratios could enhance biogas yield, paving the way for scalable applications in rural and urban settings.
