Ass fat: We like big butts and we cannot lie -- especially when we use our own to power a speed boat. Or better yet, use other people's. Bones: A Missouri plant is already turning turkey bones, beaks, feet, and feathers -- hell, probably even the gobble -- into oil. Townsfolk think the idea stinks, but are willing to take it in the name of a sustainable future. Chicken chub: According to the Des Moines Register, beef- and chicken-processing giant Tyson Foods Inc. hopes to use animal fat from its many slaughterhouses to develop biofuel.

Credit-card statements: Scientists in Germany want to use specially engineered bacteria to break down paper waste to develop biofuels. Hemp: Oh, cannabis. What can't you do? Flowers: Bouquet from your ex? Ugly hanging plant from your in-laws? Eco-fuel source! Fluffy: Finally, a good use for cats. Goodbye, kitty. An introduction to Grist's special series on biofuels.
