Bio Fuel is created by placeing organic compounds in the Crusher. Different organic products produce different amounts of biofuel. Seeds, for example, generate only 1 biofuel, whereas wheat generates 2, and bread 3. One of the steadiest and most reliable sources of biofuel is wheat farming, but pumpkin and melon seeds, as well as saplings, roses and other flowers can be used. Bio fuel can be used in the bio generator to create electricity.
