materials available from different sources, but not all waste materials are biodegradable. Only biodegradable waste materials can produce biogas. Again, the biogas generation capacity is not the same for all biodegradable waste materials .The content of biogas varies with the material being decomposed and the environmental conditions involved. Potentially, all organic waste materials contain adequate quantities of the nutrients essential for the growth and metabolism of the anaerobic bacteria in biogas production. However, the chemical composition and biological availability of the nutrients contained in these materials vary with species, factors affecting growth and age of the animal or plant [4].
