TerraCycle loves us to recycle, no matter how we do it! We can join their brigades and mail our trash to them to be upcycled into products or we can use our trash to make new products of our own! TerraCycle Toothpaste Tube Holder: Upcycle your toothpaste tubes into this fresh bathroom caddy! Looking for a refreshing alternative to throwing away your toothpaste tubes? This easy do-it-yourself project upcycles your empty tubes into a simple toothbrush holder. Upcycling materials like these are a great way to reuse without costing a mint.
