Fixed Dome Biogas Plant by Mchau

Why to choose this solution?
The solution provides alternative and clean energy for cooking instead of firewood and charcoal. Cow dung is the raw material used to feed the biogas plant to produce biogas which is used for cooking.
Savings per day or production:
Time and manpower which was earlier used to fetch firewood is now used to do something else. In a case where firewood was used, cost incurred per day was not less than 3000 Tshs.
Cost in money and in own time to construct:
The size of this Biogas is 4 m3 and costs Tsh.1,050,000. Construction of such biogas took about two (2) weeks.
10 -20 years
Maintenance needed:
Biogas require daily feeding of the feedstock.
Resources needed in use:
Cow dung
Problems and limits:
Biogas plant require daily feeding of the feedstock, in some area where water is scarce becomes a challenge
Where and how can you get it or make it?
Available in livestock keepers regions of Tanzania. The technology is disseminated by TaTEDO, Carmatec, etc.
Skills needed to produce, install. maintenance, use:
Construction and maintenance of Biogas requires a skilled technician.
