Domestic biogas
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.

Biogas energy
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.

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.

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.

  • 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.

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.

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.
