Biogas
• Anaerobic treatment
• Contain (50-70% CH4, 20-40% CO2, 1-10% H, N, O2,
CO, H2S).
• Methane (CH4):
No smoke.
Blue flame.
Higher thermal energy (2-3 times) compared to the
gas currently used in our homes.
Theoretically:
35 m3 70 kWh1 m3
1 M m3/year 35 M m3/year 70 M kWh/year
70 M S.P/year
OMW CH4 Electricity

Perspective
Consider revising the government laws, so that it could
reflect the scientific results.
Consider Full/partial Financing of unit distribution for
local use in the villages.
Research
Modifications and improvement of fermentation unit.
Study characteristics of biogas.
Study the response of different crops to OMW use in
irrigation.
Factors affecting aerobic and anaerobic fermentation.
