Old Navy and TerraCycle Partner in “The Flip Flop Replay” Program Recycles Flip Flops to Build Community Playgrounds WHAT: In an effort to further reduce waste, TerraCycle Inc. and Old Navy are partnering in a month-long drive to collect used flip flops and recycle them into four public playgrounds around the country. The community is encouraged to participate by stopping by an Old Navy store to deposit used flip flops in designated collection bins. This is the first time a nationwide retailer has initiated a large-scale effort to collect and recycle flip flops.
