The most commonly recycled plastics are those marked with No. 1 and No. 2 on the bottom, like milk and detergent jugs and soda bottles. But denser plastics -- often used in yogurt containers, deodorant cases and water filters -- are made from harder-to-recycle No. 5 plastic. One company, Preserve, is trying to make it easier to recycle No. 5 plastics with free recycling bins all over the country. The items are collected and recycled into new products, like kitchenware, razors and toothbrush handles. Find bins near you and learn more at mygimme5.com/Recycling.
