New Jersey Recycling Co. offers program for Ladue and other communities. A recycling company from Trenton, NJ has teamed up with Old Navy and Office Depot to recyle hard-to-dispose of items. TerraCycle Inc. is participating in Earth Month collections throughout the United States. TerraCycle has teamed up with organizations and school groups to collect used flip-flops and used pens. The program runs April 22 through May 21, a press release from TerraCycle said. Shoppers can deposit their old flip-flops in colorful collection bins found inside the Old Navy Store at 8881 Ladue Rd. in Ladue. TerraCycle will then recycle the flip-flops into playground materials that will be donated to communities around the country. This is the first time any nationwide retailer has initiated a large-scale effort to collect and recycle hard-to-dispose-of items like flip-flops.
