Manufacturer Specified Performance Parameters
Manufacturers specify that the GesiShamba is an easy transportable system (100 kg with nested parts), high production outcomes of about 40%, and excellent slurry (bio-fertilizer) production.
Vetted Performance Status
A case study developed by South and East Africa Energy and Environmental Partnership (EEP) identified that users save $636 USD per year on fuel costs per household, users can generate $408 USD per year per household, by using the bio slurry households experience up to a 200% increase in crop revenues, users can save about 1.5 hours per day when going from making a fire to switching on a biogas stove in a matter of seconds, a reduction on emissions by by 8.2 tonnes CO 2-eq per year per household can be achieved and the usage of the systems could prevent deforestation by reducing consumption of 7.42 ton wood/charcoal per year per household.
There are some dangers associated with biogas digesters: fire hazard, leaks and negative pressure, but since this is a small/ family size system the hazards are also lower.
