Biogas is a combustible mixture of gases produced by anaerobic digestion of organic matter in an air / oxygen free environment. It is primarily composed of methane (65-75%), carbon dioxide (25-35%) and low traces of other gases.
Biogas can provide a clean, easily controlled source of renewable energy from organic waste materials with small labour input, replacing firewood or fossil fuels. It can be utilised for electricity production, space heating, water heating and process heating. If purified and compressed, biogas can also be used as car fuel in the same manner as natural gas.
ADVANTAGES OF BIOGAS
Burns cleanly ; reducing global warming
Reduces emissions of greenhouse gasses into the atmosphere
Fuel generators to produce steam and electricity
Embedded generation and local electricity distribution network reinforcement.
Can be purified to natural gas quality to run motor vehicle engines ( used as vehicle fuel) or to supply to the local gas net for cooking , heating ( space heating, water heating, grain drying) , cooling and lighting purposes
Solves the problem of energy supply in rural areas where people traditionally use firewood, kerosene and charcoal as fuel. Provides rural population fuel for cooking , heating , and etc
Anaerobic digestion solves sanitation problems by taking in human as well as animal wastes
Unlike wind and sun energy , biogas is available at all times
