Evaluation of Cow Dung and Talinum Traingulare as a Seeding Agent for the Production of Biogas from Domestic Wastes in Warri Metropolis

The evaluation of cow dung and talinum triangulare (water leaf) as a seeding agent for the production of biogas from organic domestic wastes was conducted in Warri metropolis, Nigeria. The experiments were conducted within a period of thirty seven days in a steel bio-digester. The biogas produced was dried, purified and transferred into a commercially available 7.5Kg gas cylinder using a compressor. The results obtained showed that the domestic wastes seeded with cow-dung and talinum triangulare produced 2.1Kg and 2.2Kg of biogas respectively. Overall, from the result obtained with cow-dung and talinum triangulare, it can be seen that talinum triangulare is as good as cow-dung and can be used as a substitute for cow dung (since it is readily available) in Warri metropolis, Nigeria
