While recycled paperboard egg cartons are the greenest choice, sometimes plastic foam cartons are your only choice at the supermarket. The good news is that plastic foam is recyclable, and many communities are now accepting it in curbside recycling. But if your community does not accept it, you might find uses for the egg crates around the house. Try storing holiday ornaments in the individual compartments, or use them for crafts to sort paint, glitter or beads. You can also collect the containers and send them to be recycled by mailing them to Dolco Packaging, P.O. Box 1005, 2110 Patterson St., Decatur, Indiana, 46733-5005.
