I think that we can all agree on is that we produce too much crap.... Well, looks like that crap is useful for something other than fertilizer. They expect to produce 1,000,000 liters of Bio-Diesel each year, while at same time producing clean water. I think eventually, Diesel will stabilze at high enough prices (but not too high!) that Bio-Diesel will become widespread. In any case, thought you might be interested in this good news for once.
