Flexi Biogas / FlexiTech



Country:
Kenya
Why to choose this solution?
This technology is helpful in solid waste management, and control of invasivespecies such as the water hyacinth, Mathenge plant (prosopis juliflora) and Dodder species. It also minimizes reliance on firewood, makes cooking easier and produces less smoke (clean cooking) compared to ordinary cook stoves.The systems designed for lower energy demands for daily use are called flexi domestic. They are installed in as few as 3 hours producing gas in as little as 3-5 days and run on any biodegradable material with no need for a cow. The large scale systems built according to bigger energy needs, which are best applicable for schools, hotels, churches, children homes and any other institutions with high energy demand are called T-rex.
Savings per day or production:
According to the Environmental Frame Conditions of Biogas Technology it saves about 62% carbon dioxide emitted in the atmosphere.Flexi biogas domestic systems, eliminates the task of firewood collection and women gain 3 to 4 more hours a day for other activities.It saves the users about Ksh 500 (5 USD). Normally, the beneficiaries of this technology were spending over Ksh 1000 (10 USD) per day on firewood to fry their fish but now they spend only 500 (5 USD).
Cost in money and in own time to construct:
The cost varies as the domestic version (with capacity of 6 m3) costs Ksh 75,000 (750 USD) and the large model costs (9 m3) Ksh 90,000 (900 USD).It takes two to three hours for flexi domestic biogas to be prefabricated and installed and few days (about 6 days) for the large commercial model.
Lifetime:
10 years.
Maintenance needed:
It is easy to maintain as it only requires feeding the system with feedstock materials (biodegradable materials such as any animal dung (cow, pigs, sheep, goats, and rabbits), vegetable/kitchen waste, food waste, garden weeds, and market waste) and water regularly depending on gas usage, and also checking any leakages and the water pumps.
Resources needed in use:
The systems runs on all biodegradable materials such as any animal dung, vegetable/kitchen waste, food waste, garden weeds, market waste.
Problems and limits:
Financial constraints in installation to the usersLack of community appreciation and awareness on the benefits of biogas as a cooking option.
