well if your going to raise that old turd of an issue (yes pun)
China Population: 1,330,044,544 (July 2008 est.)
so at 0.7kg of poo per pay per person = 255.5kg per year, say avg lifespan in China is 65 thats 16607.5kg a life time.
16607.5 x 1,330,044,544 = enough fertilizer for hops.
There was a show on tv a few months back about the sewage treatment problems different countries are facing. In China they really push Bio-tanks (I think that's what they called them), they encourage rural people to install them in their homes and the poo from the family can give them a constant supply of gas for cooking etc. Apparently most of the women in these areas will only look for a husband that can provide her with one so she doen't have to spend half her day scouring the countryside for wood :lol: .
The worst topic on the program was a scientist from Japan I think it was, who because there is so much undigested protein in human feces has produced a method to extract it and make edible HAMBURGER PATTIES from it!!!!!!!!! . The good thing about this, is as I'm an old fart I probably wont live long enough to see this idea on the menu. At least we wont have to have imported chinese hamburger patties lab tested for crap content as they'll be cooking and heating with it :lol: :lol: .
