Starch-based packing peanuts dissolve in water, which is a good way to dispose of them if they cannot be reused. Polystyrene peanuts do not dissolve in water.
Non-reusable packing peanuts can be placed in the trash. Packing peanuts are NOT accepted with curbside recycling.
Local postal service providers, such as UPS, FedEx or the U.S. Postal Service, may accept packing peanuts. Contact your local location for specific information.
You can also visit the EPS Industry Alliance's website to find specific locations that will accept packing peanuts.
