fuel for cooking/lights/agricul.. from the excreta

[afshin]

I was thinking of investigating the feasibility of implementation a system that uses an anaerobic digester to produce fuel for the local community. That would be instead of simply disposing the "waste" which in that case the human bodily waste will not even be considered as "waste" but "resources". So depending on the size of the community the anaerobic digester can be different in size. The collection method will also need some more thoughts.

Any suggestions? about the use of anaerobic digesters in large or small scales?
