So can bioethanol be produced from anything that we currently consider to be waste, or does it have to be grown as a crop in it's own right? That was the main thing I was trying to work out, as it doesn't seem to me that substances such as waste chip fat can be converted into bioethanol, but then I don't know the organic chemistry behind the conversion techniques.
The other thing I was wondering was, what about the sustainability of producing the reactants and catalysts required for all of these fuel conversions? Nobody ever seems to go into that.
