Biogas Potential

According to the United Nations’ Food and
Agricultural Organization (FAO), there are about 1.3 billion cattle worldwide
(one for every five people), slightly more than 1 billion sheep, around 1
billion pigs, 800 million goats and 17 billion chickens. Between them, they
produce a lot of fecal matter, around 13 billion tons of it a year, according
to various estimates.
About 62.5 liters of bio gas can be produced
from one kilogram of cow manure. Thus 10 kg of manure can produce 600 litres of
biogas enough to prepare meal for 4-6 people for a day in India. 10 tons of
biogas can prepare biogas for 3 families in a year. So theoretically at least
10 billion tons of fecal matter should be able to prepare food for 3 billion
families.
