One enterprising company, Yak Pak, is turning old billboards into one-of-a-kind bags. There are pencil bags, camera bags, totes and messengers, all made of “upcycled” vinyl from old billboards that otherwise would end up in landfills. (Hot stat: The company says that every year in the U.S. more that 3 million billboards are sent to landfills.) To make the bags, Yak Pak partnered with TerraCycle, a business devoted to  being environmentally friendly by making products out of waste. Yak Pak, celebrating its 20th year in business, calls the billboard bags its "most innovative product line yet."
