Biogas systems are based on wet organic material (waste) decomposing in an
airtight tank, where bacteria break down the material (an anaerobe process). They
will release biogas that is a mixture of mainly methane with some carbon dioxide.
The biogas can be burned as a smoke free fuel for cooking, heating, light, generator
power or other purposes. The solid residue can be used as an organic fertilizer.
Biogas system can be fed by different organic wastes, such as cow dung, human
waste (from toilets), food waste etc., i.e. wastes that could cause health problems
due to flies and contamination of water resources etc. That means that biogas plants
could help rid of unhealthy organic wastes.
We have family biogas plants of different sizes and uses. One of the types is suitable
for rural families, while the other is suitable for urban families. Below you can find the
different uses and some related appliances.
