The Advantage of Organic Biofuel Production

Early so-called 1st generation biofuels are made by fermenting food products (e.g. grains, seeds, sugars) into short-chain alcohols (e.g. ethanol, butanol) or transesterifying plant oils into biodiesel.  Production of these fuels competes with food crops for land, reduces biodiversity, and, in the case of natural plant oils, feedstock is increasingly scarce.
