If you love to hike or camp in the great outdoors, healthy snacks like apples, bananas and oranges are easy to pack, and they have enough vitamins and natural sugar to fuel your day. But when you get down to the core or peels of these items, it may seem harmless to chuck the biodegradable waste right into the woods. The reality is, it's not that easy for the item to biodegrade on its own. Apple cores can take eight weeks to break down, and the peel can take up to two years. It doesn't break down like in a compost heap because there aren't any natural microorganisms or heat to turn it into mulch. It just sits there on top of the soil, baking in the sun. It becomes an eyesore and can attract wild animals. Instead of tossing it, pack up your waste and bring it home to compost.
