For the waste products from animals, the type and age of the animal, its feeding and living condition, the age and storage of the waste product before use are all factors that can affect the quantity and quality of the biogas produced. In general finely ground waste products produce more biogas than lumps of waste materials due to large surface area of content with the bacteria (Maheshwari and Vasudevan, 1981). In this paper we determine the quality of biogas produced from various wastes by assessing its composition.
