6. VGRRC: Renewable energies (biogas) by Susanne Hugo 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.

8. VGRRC: Renewable energies (biogas) by Susanne Hugo Batch-type digesters The anaerobic digester is made out of concrete and placed underground

9. VGRRC: Renewable energies (biogas) by Susanne HugoInlet 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. VGRRC: Renewable energies (biogas) by Susanne HugoOutlet The design includes an outlet to distribute the effluent directly to the field or into a fish pond

11. VGRRC: Renewable energies (biogas) by Susanne Hugo 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. VGRRC: Renewable energies (biogas) by Susanne Hugo 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. VGRRC: Renewable energies (biogas) by Susanne Hugo Cooking with Biogas Mrs. Hue uses biogas in her restaurant and for preparing meals for her family

14. VGRRC: Renewable energies (biogas) by Susanne Hugo 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. VGRRC: Renewable energies (biogas) by Susanne Hugo 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. VGRRC: Renewable energies (biogas) by Susanne Hugo 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
