ABSTRACT
Household energy is increasingly becoming a scarce resource in developing countries. In
these countries, cooking accounts for about 80% of all household energy consumption.
Motivated by the need to meet the ever-increasing energy demand and sustainability
consciousness, some establishment and organisation have promoted renewable energy
technologies such as biogas. However, further development of biogas technology in
developing countries is constrained by lack of proper understanding of the populace and poor
management of waste of different categories. This paper presents the findings of a research
that was carried out to determine the generation of biogas from cow dung using a low cost
fabricated bio-digester.
A cylindrical drum of capacity 175 litres was used as bio-digester and fed with 80kg of cow
dung mixed with warm water in proportions of 2:1. Also, calcium hydroxide [Ca (OH)2] was
incorporated into the experiment to remove the carbon(IV)oxide from the biogas yield.
Results from this study shows that the digestion of cow dung resulted in an appreciable
biogas yield. Comparing this result with sample of cow dung mixed with warm water in the
ratio 1:1 and taking into account the natural state of the waste when collected for experiment,
it is of considerable range when compared with the standard values. Ultimately, digestion of
cow dung is one way of addressing the problem of insufficient gas production in developing
countries.
Key words: Biogas, cow dung, digestion, Developing Countries.
