Don’t throw your packing peanuts away. Save them for personal reuse or recycle. I had collected a large bag full that was taking space in my basement. I brought it over to my local UPS Store, and they took it without any trouble. I was in and out in about 10 seconds. Find your closest UPS Store and call to make sure they accept recycled peanuts (most do).
You can also visit The Peanut Hotline (or call 800-828-2214), the national reuse program for plastic packing peanuts. They coordinate more than 1,500 collection sites in the U.S. Enter your address to find sites near you.
