USING A BIOGAS
DIGESTER
Introduction
The use of biogas for day-to-day activities is something that happens on a large scale worldwide.
In countries like China and India the waste produced by large factories and households flats etc is
being used to produce biogas. It has also helped to reduce environmental pollution.
This document concentrates on small-scale domestic biogas digesters. Our objective is to build
awareness on how to properly maintain a small biogas digester and what needs to be done when
minor malfunctions occur. The reason being as the result of research carried out suggesting that
the majority of biogas digesters become inefficient due to minor malfunctions.
The production of biogas is:
An easy method of obtaining combustible fuel required for domestic consumption though the
systematic management of waste.
When do you use a biogas digester?
1. As a substitute for firewood or LP
gas used for cooking.
2. As a substitute to the traditional
oil lamps used to light the
household.
3. If the biogas digester is large it
can be used as a substitute for
the fuel used to run an engine.
4. As a method of obtaining
fertiliser that can be used
instead of chemical fertilisers
used for cultivation.
