Biodegradeable cardboard hangers

HangerNetwork makes biodegradeable cardboard hangers, or EcoHangers, that work as well as wire ones, but are easier to recycle. The company gives the hangers to dry cleaners for free, making money off ads on the hangers themselves. HangerNetwork says it's growing revenue by 300 percent a year.
