I have seen many references to producing ethanol from waste bread but cannot find a recipe anywhere. I would be grateful for any recipe with possible required enzymes, yeast type method etc. As it breaks down easily does it require cooking and so on. Still not exactly sure if I want to run car on ethanol or use ethanol to make biodiesel. Both have problems with first requiring flex fuel car and the second requiring the finding of stable WVO supply. Was set to go with biodiesel a couple of years ago but of course human greed being what it is some people could not possibly stand by and let the ordinary bloke make enough fuel for himself but had to corner the market in WVO and profit from it selling biodiesel at prices very little different to the pump prices. To me they are no better than the terrible oil companies.
