What does this even mean? Good question. Princeton freshman dropout Tom Szaky (CEO Terracycle) makes amazing all-natural fertilizer from worm poop, and packages it in unprocessed used bottles. In addition, the stuff is made in a run-down warehouse using old horse feed-troughs collected from farms. A really cool business model: he doesn’t simply reconceptualize his product, but also every step of production, by using trash as much as possible. This way, he can dramatically cut costs and save valuable material resources. His company also makes reusable grocery and school bags from upcycled plastic grocery bags, other school supplies, eco-friendly cleaners, animal feed, fire starters (eh…) and more.
