Biogas produced from cattle, pig and buffalo dung (and other excrement, e.g. human), together with the by-product bioslurry, can be a solution to poor access to modern energy services, poverty, climate change, and soil fertility problems.
It is a simple and affordable energy supply which is uncomplicated to handle and easy to maintain. Indeed, it is the cheapest option so far for clean energy provision to rural households. This makes it ideal for smallholder farmers and families with just a few cattle. The potential of biogas is significant in developed as well as developing countries. A biogas installation can be filled with locally available raw materials, crop residues and animal and human waste and the by-product (bioslurry) can be used to improve soil fertility, soil structure and crop productivity.
