Gadget geeks Upcycled snack bag speakers by TerraCycle and Merkury Innovations are made from recycled snack bags that have been melted into plastic. They’re great for an iPod or MP3 player and are universally compatible and battery-free (they run off of your device’s power supply).

Price: $14.99 These iPod speakers are made with wrappers from food conglomerate Mars that would have gone to waste. The speakers come in different designs, either M&M wrappers, Skittles or Starburst (pictured here). The speakers don’t require batteries or need to be plugged into an outlet, making them safer for the environment.
