Until tomorrow, people can take their unwanted pens, markers and mechanical pencils of any brand to Office Depot. TerraCycle, a recycling company, will then use them to make office supplies like organizers and trash cans.
Meanwhile, until May 21, people can take their unwanted flip-flops to Old Navy. TerraCycle will mix, melt and extrude the footwear into plastic boards. The boards then will be used as structural pieces in playgrounds which will be donated to communities across the country.
