“The production of biogas, which is regarded in many countries as a by-product of an efficient system of energy production, has become in China a comprehensive, controlled method of waste disposal, recycling resources, supplying energy & fertilizer, and improving rural health, as the digesting of wastes in a closed container kills many of the pathogens responsible for common human diseases.”
- quote from - A Chinese Biogas Manual (ISBN 0 903031 65)
A couple questions I thouht of: Is there any info you've seen on capturing human wastes to be included with the animal waste in producing the methane gas?.
I'm thinking of some combo of an enclosed bacteria-composting-potty connected to an 'enclosed septic tank-bio-gas generator', that both captures the gas from decomposition, and captures & stabilized the nutrients in a form they can later safely be utilized for maintaining soil fertility & tilth?
Do you know the ideal time range in our cool northern climate for allowing the anaerobic animal resources to stay in the enclosed container before coming out onto the earth?
And, is there a secondary aerobic composting process for these materials before they are added back to the soil's fertility cycle?
I'm wondering what type of 'fuel cell' you're considering using.
The links you posted are great! I'm trying to recall if we have a place on our Transition whatcom site to file good links like this into an 'online library' of sorts.
