Plastic bags are not recyclable in the blue recycling cart.
Plastic bags are made out of "film", or thin flexible sheets of plastic. Plastic film is typically defined as any plastic less than 10 mm thick. The most plastic films are made from polyethylene resin and are readily recyclable if the material is clean, dry, and not pigmented black.
Recycle (Please check with the store that provided you with the bag to see if it will take it back to be recycled)
Check with Waste Connections, Inc. Washington for the Transfer Stations and new material collection.
