2. Context : Energy Situation in Bangladesh
 Around 100 Million people
have no access to grid
electricity
 Only 3% people have access
to gas through pipelines
 Lack of energy is one of the
major reasons for rural
backwardness
 There is potential of 4 million
Biogas plants in the country
 Climate in Bangladesh is
suitable for Biogas production

9. Biogas
Biogas is produced decomposing
organic materials (mainly animal
wastes) in an anaerobic condition.
Major component of this gas is
methane (CH4). It has no color,
smell and it burns like natural gas.
This Biogas use cooking, power
to lighting.

10. Why Biogas?
 Our climate is suitable for biogas production
 Raw materials are easily available
 Technology is simple and locally available
 All hazardous materials are the raw materials
of a biogas digester like poultry farm waste
 No access of natural gas in rural area
 Shortage of electricity
 Environmental Development

11. Improvements of Biogas System
• Mixing Device
• Turret
• Pipeline
• Hydraulic Chamber with slab
• Burner
• Slurry Processing
• Water Drain
• Cooking Practice

12. Constructing Commercial
Biogas Plants

13. Commercial Biogas Plant

14. Domestic Biogas Plant

15. Poultry Farm Biogas

16. Economic of Biogas Technology
• Saving of expenditures on fuel sources
• Saved time to utilize in other income
generation activities
• Enhanced soil productivity because of the
use bio-slurry (added N,P,K values)
• Reduction in the quantity of chemical
fertilizers due to the use of bio-slurry
• Reduction on health expenditures due to
decrease in smoke-borne diseases
• Employment to local people
• Private sector development that produces
economic goods

17. Other Benefits of Biogas
• Reduction of work load, especially for
woman
• Biomass Saving
• Useable Organic Fertilizer
• Better sanitation (if toilets attached)
• Improvement of health condition by
reducing Indoor Air Pollution (IAP)
• Employment generation
• Reduction of green house gas
emission
