Crap into coal ??

[I-K-E]

been thinking about this during the day and I agree about industrial scale before the SHTF
after we could well be living a semi subsistence and would working something like this be taking too much out of the land where we maybe living?

if you process the green waste to give fuel rather than compost it and return it to the garden you will soon drain the resource in the soil. Same with live stock crap helping to feed and maintain pastures

Maybe I have been reading to much about permaculture on a blog I found a few days ago?
