Hively Avenue Preschool is trying to win a playground made from recycled oral care waste through the second annual Recycled Playground Challenge, sponsored by TerraCycle, Colgate and Meijer. The school will earn on ‘Playground Credit’ for each shipment of empty toothpaste tubes, toothbrushes, and floss containers sent to TerraCycle by the students and teachers, and one credit for every online vote cast for the school at www.meijer.com/colgate by June 18, 2016.
