Financial plan
Our goal for this project is to build a small biogas-installation and use this as a prototype to support the transfer of knowledge to the local farmers. We built the installation at a girlsschool in Matunda to produce gas for them to cook on. But for the installation we need funding. Our plan is to fund the installation together with three parties. First the rector of the school pays a part of the installation with their own savings and maybe partly by microcredit. Secondly there is a good friend of the schools who wants to help with financial support for this installation. Lastly our group of three students will pay a small part of the installation to show our good intentions to the project and to bear a part of the expenses. At this point we don’t know exactly the amount of money we need for the installation, that depends also on the size of the installation and the partner we work with. Our estimate for the expenses of the installation is between 200.000 – 300.000 KES, this is about 1725 – 2600 euro.
The school has 11 cows, who produce in totale 110 kg dung per day. From 1 kg dung the production of gas is 0.03 m3. So the school will produce 3,3 m3 biogas per day. With the 11 cows we can build a biogas-installation with a capacatiy of 15m3, such an installation must be filled with 110 kg dung a day. This is the amount of dung that the cows can produce per day, so this would work.
A cooking stove use 0.4 m3 gas per hour. The school has approximately 3 stoves working at the same time and the stoves are used from 4:00 am until 19:30. So the school use about 18,6 m3 gas per day
The production of the biogas-installation can produce 1/6 of the required gas, so there is 1/6 less firewood needed. Per year are 5 lorries wood used that per lorry cost 45.000 KES. The school can cut their cost in wood with 1/6, that is 37500 KES. So the biogas-installation can be paid of with 37500 KES per year, that comes to 5-6 year return time.
