Biogas – The source of future energy
energy (cooking, heating and boiling water) in rural areas, the daily per capita
demand of energy equals about 13 kWh which could be covered by about 2
m3 of biogas. A biogas plant therefore directly saves forest.
Annually, each biogas plant can save more than four ton's of firewood and 32
liters of kerosene.
A single biogas system with a volume of 100 cubic feet (2,8 m3) can save as
much as 0.3 acres (0,12 ha) of forest (woodland) each year.
A recent study by Winrock, Nepal and others found that each biogas plant can
mitigate about five tons of carbon dioxide equivalents per year.
Dangers of biogas
Anaerobic digestion systems and associated manure storage and handling present
many safety hazards. A good designer and responsible digester owner will learn
about and be concerned with safety from the very beginning of any digester project. A
qualified digester designer, builder or equipment supplier should have excellent
