Generation of Biogas from Sewage

This research investigates the production of biogas from sewage as a sustainable alternative energy source and a means of addressing environmental pollution. The study was motivated by the growing need for clean energy solutions and proper management of organic waste. Sewage generated from toilets within the. Department of Science Laboratory Technology of Ogun state Institute of Technology Igbesa were collected in underground tank. A 500-liter airtight plastic tank was used as the main digester, with auxiliary materials such as plastic pipes, hose, T-junctions, inner tube (as a gas reservoir), caustic soda (for gas filtration), The system operated under anaerobic conditions, and biogas was collected in the inner tube after a few days of fermentation. Visual observation confirmed gas generation and successful storage, as evidenced by tube expansion and subsequent gas ignition. With the aid of a booster the collected gas was passed through pipe into the laboratory. The aim of this is to replace the conventional compressed gas supply with biogas. This had also help to reduce the running cost of the laboratory.
