#1 Plastic Clamshells

At this time, Waste Management is unable to recycle #1 plastic clamshells (typically used for salad, berry and other produce containers) due to the way they are manufactured.

Pet Food Bags

Animal feed or bird seed bags are NOT acceptable in curbside recycling.
These bags are typically layers of different materials and once those layers are together, it's hard to get components separated so that they can be made into new things. Still not sure? Do the 'tear test'....if you can easily tear the bag and don't see a plastic film layer mixed with the paper, it's good to go for recycling.

Plastic Bags & Film

Reduce, Reuse, Recycle - in that order. Use reusable bags so you have fewer plastic bags. If you can't reuse, then recycle at a participating retail store.

All plastic bags and film are not accepted in curbside recycling. This includes: grocery/retail bags, mattress/furniture covers, newspaper bags, bread bags, dry cleaning bags, plastic wrap from toilet paper rolls, napkins, paper towels, bottles of water, etc., produce bags, frozen vegetable bags, food storage bags, bubble wrap and air filled bags for packaging.

Why? Loose bags, and even bundled bags, get wrapped around recycling equipment and jam the screens at the processor. Plastic bags do A LOT of damage to the curbside recycling processor equipment. 

Plastic Bag Recycling Locations & Accepted Materials
