Office Depot (NYSE: ODP), celebrating 25 years as a leading global provider of office supplies and services, together with TerraCycle, Inc. will be offering customers a unique recycling opportunity during Earth Month. Beginning Sunday, April 17 and running through Saturday, April 23, customers can trade in their used writing instruments, regardless of brand, to any Office Depot retail store location nationwide. In exchange for ten pens, pencils or markers, customers will receive a coupon toward a new product from Newell Rubbermaid Office Products, maker of Sharpie(R), EXPO(R), Paper Mate(R) and more. The collected instruments will be sent to TerraCycle, the pioneering upcycling and recycling company, to be turned into new office supply products ranging from trash cans to desk organizers.
