Justification in NRS Context:
- Electricity available in major Towns only - maximum city power availability 30-60 hours
a month
- NRS one of the most suitable places - average temperature around 20–30 degree Celsius
- About 80 % of the total dung from over 234,382 heads of cattle & buffalo can be made
available
- Assuming 10 kg fresh dung per cattle/buffalo head per day and 0.037 cum biogas/kg
fresh dung, the biogas potential stands at 0.253 million cum per year = about 0.133 million
tons of oil
- A total of 75 family size (Radius 8’3” x height 6’6”), fiberglass biogas plants, Yangon made (designed in China), installed in NRS.
Access to production resources and support services:
Production Resources: Prefabricated fibreglass dome biogas plants available in Yangon Prefabricated fibreglass dome biogas plants available in Yangon
Support Services:
-- Practical trainings on biogas operations and maintenance providedPractical trainings on biogas operations and maintenance provided
-- PostPost--installation services of biogas plants constituted an important component installation services of biogas plants constituted an important component
-- Local supplier of digester is providing maintenance of the biogas plants through FAO Local supplier of digester is providing maintenance of the biogas plants through FAO

Outcome in terms of livelihood improvement: i. Gender benefits: Saves approx. 4-5 hours time a day per family - reduction on time used
for collecting fuel wood, cooking and cleaning of utensils
ii. Environmental benefits: Improves indoor air quality, reduces pressure of deforestation,
bio-fertilizer improves soil structures, and reduces CO2.
iii. Health benefits: Reduces smoke exposures - improves the health condition especially eye
infection, respiratory diseases, cough and headache
iv. Economic benefits: Reduces almost 90 % expenses on fuel. Bio-fertilizer = high yield of
crop and vegetables crop and vegetables
Income from the sale of the processed derivativesCurrently,
Biogas effluent used for composting or for direct application as manure, and
Reformation of saline-alkali soil in small scale as demonstration. Initial response
good, however, effect of reforming soil can be shown in two or three years after
the spread of biogas manure.
Research findings indicate:
1. Pond fish raising with biogas effluent give better productive efficiency than that
of pond fish raising by manure directly
2. Biogas effluent improve water quality, increase the amount of dissolved oxygen 2. Biogas effluent improve water quality, increase the amount of dissolved oxygen
and ammonium nitrogen and reduce CO2, parasites and fish diseases
