Egg Cartons are not recyclable, but are easily reused or composted.
Reuse is a great way to extend the life of materials and keep them out of the waste stream. Try these ideas:

Raise Chickens
Raising your own chickens allows you to not use egg cartons, although you still might find them handy for storage.

Give Them Back
Return empty egg cartons to the market or farmer for reuse.

Get Organized
Use egg cartons as storage containers for organizing small items such as beads, seeds, or fishing lures.

Plant Seeds
Egg cartons make excellent containers for starting seeds.
