What we do Research Extension
Training

• Integrated Farming Systems
• Sustainable Development
• Goat, sheep and rabbit husbandry
• Renewable Energies

Results achieved so far

• are based on simple low-cost technologies and on
  training. The main beneficiaries are small-scale
  women farmers who not only carry out much of the
  work at farm level but who were and continue to
  be the processors and marketers of their high
  quality products.
• Biogas technology is a complete system in itself
  with its set objectives (cost effective
  production of energy and soil nutrients). The
  residue is known as effluent.
• It is an almost pathogen-free stabilized manure
  that can be used to maintain soil fertility,
  fertilize fishponds end enhance crop production.
• This approach enabled the provision of a higher
  rates of return to farmers and has contributed to
  a successful and sustainable operation of the
  farms.
• This approach also attracted significant
  attention from other donors.

Methane (Biogas) from Anaerobic Digesters

• Mrs. Hue and her family had a biogas system
  installed in Spring 2002
• Mrs. Hue has a small restaurant in Ba Vi village
• Her husband is fattening pigs in the backyard

Batch-type digesters

• The anaerobic digester is made out of concrete
• and placed underground

9
Inlet

• The design consists of
• an inlet
• connecting the stable to the biogas digester
• manure is washed into the digester when the
  stable floor is flushed with water
• this reduces the work load of the farmer
  considerably

Outlets from empty stables can be temporarily
blocked with rocks
10
Outlet

• The design includes
• an outlet
• to distribute the effluent
• directly to the field
• or into a fish pond

11
Processing of wastes for energy recovery
nutrient recycling

• The solid material drawn from the digester is
  called sludge, or effluent.
• It is rich in nutrients
• ammonia, phosphorus, potassium
• and more than a dozen trace elements
• It is an almost pathogen-free stabilized manure
  that can be used to maintain soil fertility,
  fertilize fishponds end enhance crop production.

• here, the effluent is used to fertilize a
  fishpond

12
Cooking with Biogas

• Biogas is odourless
• The flame is bright, and burns steadily
• All types of gas cookers available in Son Tay can
  use biogas

13
Cooking with Biogas

• Mrs. Hue uses biogas
• in her restaurant
• and for
• preparing meals for her family

14
Improved living conditions

• A new toilet was built, improving the familys
  sanitary conditions
• the toilet is also connected to the biogas
  digester, thus processing human wastes

15
Direct impact

• Reduced fuel demands eases the workload of the
  women who collect it
• Reduced needs of fuel wood results in
  considerable savings for the household
• Women are less exhausted and spend more quality
  time with their families
• The reduction in pollutants improves the health
  status of the women who work in the kitchen

Women in Kim Son, Son Tay transport the fuel wood
needed on their way back home from work in the
factory
16
Converting Manure

• Biogas offers an environmental-friendly way of
  converting manure into methane and almost
  pathogen-free stabilized fertilizer
• its primary benefits are
• waste treatment
• converting manure into energy and almost
  pathogen-free stabilized manure fertilizer
• odour control
• nutrient recycling on-farm

17
Extension

• Regular extension visits are made
• VGRRC provides assistance and advise
• VGRRC co-operates with local women unions the
  German Development Service (DED) and the
  Netherlands Development Organisation (SNV) in
  setting up biogas units in Ba Vi and Son Tay

Training courses for subsistence farmers in their
villages

• VGRRC offers training courses for subsistence
  farmers
• at VGRRC
• at their villages

• Participants of a training course in Van Hoa,
  November 2002
