The question is exactly how it sounds in the title. Has anyone installed a biogas digester in place of a septic tank? I'm located in zone 6. Heres a couple links, one on cold climate and one on the us military building bio gas reactors in Afganistan.

- Recently I saw quoted a performance figure for a biogas generator(s) run only with the 'night soil' of a family of 5. Total production of biogas was 25 kilos / 55 lbs.

Yearly ! This figure is approximately 1/8th to 1/10th of the typical Amount of Gas by volume of propane ( which is MORE energy dense ) for a typical American family

of 4 !

Also when using animal manure the 'payback period' is much Extended as compared to a Biogas generator started on Manure and switched over to household

garbage as the sole feed stock!

Hopefully this is timely and useful ! Big AL


Late note : Yes, this is a good location for Biogas generation, a common trick is to insulate all but one south/solar facing side and spray that side flat black to

increase solar gain without producing an overgrowth of Algae A.L.
