  3. Domestic biogas • Large scale dissemination of household bio-digesters; • Minimum daily feeding 20kg of animal dung (cattle, buffalos, pigs, chicken) possibly with a toilet attachment, maximum feeding about 200kg; • Replacing about 5kg of firewood, 1.5 kg of charcoal or 0.6litre of kerosene per 25kg dung/day; • Investment cost in Asia between US$ 350 and 800. In Africa considerably more expensive.

  4. Biogas: energy … • Over 2 billion people worldwide lack access to clean, safe and sustainable domestic energy services. • Lack of access to adequate, affordable, reliable, safe and environmentally benign energy is a severe constraint on development. • A lack of access to clean and affordable energy can be considered a core dimension of poverty.

  5. and so much more … :

  6. MDG & domestic biogas I MDG 1 Eradicate extreme poverty and hungerTarget 1 To halve extreme poverty • Construction and installation of biogas creates employment for landless rural people. • Biogas saving on the use of traditional cooking fuels increases the availability of these fuels for (very) poor members of the community. MDG 3 Promote gender equality and empower womenTarget 4 Eliminate gender disparity in education. • Domestic biogas reduces the workload –collection of firewood, tending the fire, cleaning soot of cooking utensils - with 2 to 3 hours per household per day. • Biogas illumination is highly appreciated for lighting, facilitating reading / education / economic activities during the evening.

  7. MDG & domestic biogas II MDG 6 Combat HIV/AIDS, malaria and other diseasesTarget 8 Halt/reverse incidence of malaria and other diseases. • Biogas substitutes conventional energy sources, virtually eliminating indoor smoke pollution and, hence, the related health risks (e.g. respiratory diseases, eye ailments, burning accidents). • Biogas greatly reduces the workload involved in the collection of traditional cooking fuels like wood.

  8. MDG & domestic biogas III • Biogas significantly improves the sanitary condition of farm yard and its immediate surrounding, lowering the exposure of household members to harmful infections generally related with polluted water and poor sanitation. • Proper application of bio-slurry will improve agricultural production (e.g. vegetable gardening), thus contributing to food security for the community.

  9. MDG & domestic biogas IV MDG 7 Ensure environmental sustainabilityTarget 9 Integrate the principles of sustainable development into country policies and programmes and reverse the loss of environmental resources. • Particularly larger biogas dissemination programmes have a considerable governance component. As such, they positively influence national policies on sustainable development (e.g. agriculture, forestation) as well as promote participatory governance involving women and other disadvantaged groups.

  10. MDG & domestic biogas V MDG 7 Ensure environmental sustainability Target 10 Halve the proportion of people without sustainable access to safe drinking water and basic sanitation. • Biogas reduces fresh water pollution as a result of improved management of dung. Connection of the toilet to the biogas plant significantly improves the farmyard sanitary condition.

  11. Development at different levels • Farmers; • Craftsmen, engineers and maintenance workers; • Governments; • International Community.

  12. Course Topics Technical aspects bio-chemical process, plant designs, plant sizing, appliances Economic aspects financial returns, subsidies, emission calculations and marketing of credits Large scale dissemination programme set-up / sector development

  13. Download biogas simulation software from: http://envirosim.com/bw31setup.exe All materials will be available by the end of the week on: http://sites.google.com/site/biogas4all/ . We hope you’ll enjoy the course, Henri, Steven, Felix.
