TerraCycle is launching a new campaign with Old Navy next week called the Flip Flop Replay just in time for Earth Day. From April 22 through May 21 you can drop off used flip flops at any Old Navy store in the U.S. Then TerraCycle will recycle the flip flops into four public playgrounds at different locations around the country, marking the first large-scale effort to collect and recycle flip flops. TerraCycle has led the recycling charge with several successful programs in the past including recycling Stoneyfield yogurt containers into toothbrushes, razors and more. Beyond flip flop recycling, you can join in on one of TerraCycle’s other “Bridgades” by sending in wrappers, corks, containers, electronics and more.
