Affordable Bio-digesters for household level

Re: Affordable Bio-digesters for household level
Dear Mutala,
Here is a model we use in Nepal:
Whether it is affordable depends much on local building material costs, and available skills.
As Arno suggests, the use of biogas at the household level will need more feeding inputs than the human excreta only. In a warm climate, a mixed feeding system of 2 cubic meter capacity should be able to deliver about two hours of cooking time (depending also on local cooking habits and stove quality). To produce the maximum amount of gas, a two cubic meter system should be fed around 10-12 kg of feeding material per day. (Feeding material could be human waste, kitchen waste and manures.) Since a family of 6 will only produce between 1 and 1.5 kg of feces per day, you still need to add 9-10 kg per day of manure or kitchen waste.

Marijn

I also link to a brochure describing SEI's REVAMP model to determine what value you can expect from organic "waste streams".

We see that sludge, food and farm wastes need to be combined in order to create the scale required to make a significant impact on a community.

Helloo;
I am from the Institute for Sustainable Energy and Environmental Solutions (ISEES)-Ghana.
We are currently looking for appropriate technology to install bio-digesters for low income urban households at affordable rate. We have a number of technological designs; however, we would be glad if members will be willing to share their experiences and different technologies that have proven to adopt well especially in the African climate.
I look forward to receiving your suggestions. Thank you.
