The practicality of a compost bin is that it transforms items you might otherwise throw out into gardening 'gold. ' this soft brown organic material enriches the soil and does wonders for plants that could use a little boost. Keep in mind that veggie and fruit scraps aren't the only things you can compost. Stale herbs and spices, matches, refrigerator lint, popcorn, post-it notes, pet hair, wool socks and toenail clippings can all be composted as well.
