From The Daily Green's Jeff Yeager:
"A rind is a terrible thing to waste." If you're a composting enthusiast like me, that's our mantra.
Nearly all fruit and vegetable skins can be added to the compost pile. But since I'm the Ultimate Green Cheapskate, I like to get even more mileage out of my rinds - at least before I deposit them in my compost pile.
Try out these creative uses for your peels next time you're thinking about heading out to the compost pile. (Warning: The skins of vegetables and fruits that are to be consumed or come in contact with food should be thoroughly washed first, even if organically grown.)
