The remnants of animal such as bone, organic waste from slaughter house and fishery animal dung, and human dung are classified as animal waste biomass [49]. Earlier, animal dung was used mainly as fertilizer or kitchen fuel. However, a huge amount of waste used to be simply spread on fertile land which was the reason for many environmental issues and later crafted into waste-energy conversion. Biogas obtained from anaerobic digestion of above organic waste is an attractive alternative of kitchen fuel or converting gas energy into electric energy.
