Fixed-Dome Biogas Plant by ECOSAFE Ltd

Why to choose this solution?
Clean energy, improved kitchen hygiene/ sanitation, and quality bio slurry (manure) that results in better yields (crops, fisheries, piggery) are co-benefits.
Savings per day or production:
Faster cooking saves time and money. For example, 1 kg of dry beans can be cooked in one hour with biogas (constant heat), which is not possible with firewood and charcoal. According to Mr Kasule, biogas user in Nakaseke, crop health and yields have improved since he started applying bio slurry to his banana crop, feeding it on his fish and pigs. Savings have occurred as a result of adopting this biogas energy option.
Cost in money and in own time to construct:
A 9 m3 biogas plant costs USh 1.8 million (approx. USD 493) and can be done in 7 days.
25 years, according to ECOSAFE Ltd.
Maintenance needed:
Resources needed in use:
Small and medium farms for (zero-grazing) cows or pigs that can provide at least 75 kgs of cow dung per day.
Problems and limits:
Cost of setting up the biogas plant is expensive for many people. Managing biogas lamps, as moths and insects lead to tearing and breakages. High temperatures involved (650 to 700 C degree) mean generation of too much heat. Labour-intensive to sustain biogas production, as there must be daily stirring of feedstock dung in the mixing tank.

Where it is used and how many users are there?
Kasana parish, Kikyuusa Parish, Semuto sub county in Nakaseke district.
Why is it successful?
Cumulative fuel and other savings (fertilisers, medical etc.) of Ugshs 2,881,200 after 22 months of operation (Ecosafe Ltd) compared to 1.8 million Ugshs investment; Lifetime of 25 years means cumulative savings over a long period of time. Bio slurry (fertiliser by product) can be applied to crops for increased yields of up to 30%; insect repellant on bananas, oranges, coffee (Biogas Uganda Ltd & Sam Kasule); bio slurry is also an excellent nutritious feed for pigs -results in savings made on animal feeds; chicken manure, with its nuisance smell for urban farmers, can be used in recommended proportions as a source of feedstock for the biogas plant.
