What is a Biogas Plant?
A biogas plant is a biological active system designed to
accelerate biodegradation of organic waste by anaerobic
digestion. In the process, biogas is produced and recovered
for utilization instead of being emitted into the atmosphere
and contributing to global warming. Biogas consists of 50 –
70% methane and the balance mostly carbon dioxide. The
remaining digestate is a valuable organic fertilizer. Thus,
the system recycles organic waste and enables full
utilization of its energy content.
Organic wastes that can be used as
raw material for a biogas plant are as follows:
Livestock farm manure and slaughterhouse waste
Fruit and vegetable market wastes
All kinds of food processing waste
Palm oil mill effluent (POME)
Garden and household food wastes
The benefits of a biogas plant are
1) Environmental protection – helps to reduce emission of
greenhouse gases (mainly methane, CO2) into the
Biogas produced can be upgraded to biomethane and
used as fuel for cooking, heating, or fuel for NGVs
Biogas can also be used to run a gas engine or
turbine to generate electricity.
The process reduces organic waste to a valuable
bio-fertilizer and thus recycles them back the soil.
When integrated into a food processing, livestock framing or
palm oil mill operations, it would enhance their
profitability and also at the same time, contribute to
environmental protection via reduced GHG emission.
