- Biogas and biomass
- Kenia: Biogas from cow dung
|Total savings :||4,000 tonnes CO₂ per year|
|Technology transfer :||Biogas units for the energy supply of households|
|Local environment :||Replaces wood, gas and kerosene, prevents deforestation, and produces the useful by-product slurry (fertile liquid manure)|
|Further advantages :||Creates jobs in the construction and maintenance of the biogas units|
|Project partners :||Sustainable Energy Strategies (SES), Action for Food Production (AFPRO)|
Together with the Kenyan company SES, atmosfair builds small biogas plants of 2-3 m3 in the Nairobi River Basin in Kenya. By using the biogas plants, the participating smallholders can go without wood and other fossil fuels. Each biogas plant saves about 5 tons of CO2 per year and at the same time preserves the forest and its biodiversity. For households, the switch to biogas is particularly attractive because they save on firewood costs and no longer have to collect up to 10 kg of firewood a day. In the project region, it is common practice for smallholders to rear 2-3 zero-grasing cows in close proximity to their houses. The families can therefore easily collect the cow dung and use it together with agricultural waste and water to run their biogas plant. The biogas produced is fed directly to the new gas cooker via a pipe connection.
During the process of biogas production, a nutrient-rich agricultural fertilizer, slurry, is produced as an additional produc. Many farming families use the fertilizer to grow organic vegetables in their own farms. Through the training of craftspeople on site, the knowledge for the construction of plants for decentralized energy supply remains in the country and contributes to the energy transformation in Kenya in the long term.
Even if the biogas plants recover their costs over time due to the savings in the procurement of fuels, the initial investment represents a major hurdle for many households. In Kenya, there are no public funds to promote household biogas plants without international support. atmosfair subsidizes so that households can afford the plants. Each plant is also supported with a grant from Grüner Strom Label e. V.. The households themselves pay the difference to the purchase price.
The last project appraisal again certified that all the project’s facilities examined are still in use 11 years after construction. This is due to the robust method of building and high quality of the plants. On the other hand, SES offers quick help in case of technical problems and takes care of the repair of the plants.
For the construction of the biogas plants, atmosfair works closely with the Kenyan company Sustainable Energy Strategies Ltd. (SES) founded in 2008 in Nairobi, which is one of the central private actors in the field of biogas. At the beginning of the project, SES also supported the Indian NGO Action for Food Production (AFPRO) by training local craftspeople who now build the biogas plants independently and train other craftspeople themselves.
