Apart from animal dung biogas can be also produce from
wastage of slaughter houses, paper industry, street waste, banana
stem waste and poultry waste [31,63]. A cow/buffalo can produce
15 kg average dung per day. 1 m3 can be produced from 6 kg of
dung, so an average of 2.5 m3 biogas can be produce by single cow/
buffalo in a day [64]. Poultry waste is considered ideal substrate
for production of Biogas [65]. Poultry sector in Pakistan also has a
robust growth of 7–8% annually [3].
