What is one business idea that you’re willing to give away to our readers? I’m fascinated by waste. TerraCycle is one of those innovative companies that has figured out a way to reuse waste and turn it into a profitable business by changing the way people think about and handle their trash. ecopop spent months trying to figure out how to make products out of shredded office paper. An industrial designer and I played around with various eco-epoxies and pulp molds to make everything from paperweights and bookends to garden gnomes and decorative plates. We ended up pulling the plug after our 90-day proof of concept phase, but I still think there’s a viable business idea there for anyone who wants to develop this idea or invent products made from waste.
