The study revealed that it is possible to produce biogas from a mixture of water hyacinth and cow dung. The simplicity of the operating procedures of the digester with a scrubber and a gas bag is an advantage that can easily be replicated for household use. Biogas is a good quality fuel that can be used as a replacement for firewood and several other energy sources. The study’s evaluation of production potential over a 30 days period revealed marked seasonal variations in biogas outflow.
