Paper Egg Cartons Are Recyclable Email Paper egg cartons are recyclable! To recycle your egg cartons, make sure they are clean and dry. If you place eggs back in the carton after cracking them, the carton is no longer recyclable due to the food residue. Food residue will contaminate the recycling process. Paper egg cartons are a more eco-friendly choice than either plastic or foam egg cartons. Why? Not only are they recyclable, they’re also made from paper that has already been recycled. They are biodegradable, too! Learn more about paper egg cartons.
