Lightweight “peanuts” made from expanded polystyrene (EPS) contain 25 to 100 percent recycled materials. The Plastic Loose Fill Council has a “Peanut Hotline” (800-828-2214) you can call to find local recycling centers. To recycle large, molded chunks of EPS used to cushion televisions, air conditioners and such, contact the Alliance of Foam Packaging Recyclers.
