When you look at community playgrounds, the last thing you’d assume those playgrounds are built from is flip flops. But Old Navy and TerraCycle are partnering together in a program that makes that happen. The Flip Flop Replay program facilitates the recycling of old flip flops to build community playgrounds. It’s all part of a national recycling program. Now through May 21, Old Navy shoppers can participate in Flip Flop Replay by depositing used flip flops in collection bins at local Old Navy stores.
