Why can't I put my bags in with my other curbside recycling?

Films are not recycled when included in Mercer County curbside recycling and these must be taken separately to one of the drop locations listed above. Additionally, bags and films can jam sorting machinery, creating problems for the businesses that sort recyclables.


Why can't frozen food or prewashed salad bags go into the bin with my carryout bags?

Many of these bags may contain a barrier polymer or other additives that is not the polyethylene (#'s 2 and 4) plastic that recyclers want. These polymer barriers help protect the food and extend shelf life but recyclers consider them to be a contaminant in the recycling drop off points.


Can I recycle it if...

The plastic is colored?
YES. Colored material is not a problem for recycling.

It tears like paper?
NO. This type of plastic is currently not accepted in bag recycling drop off points.

It crinkles loudly and is silvery or metallic (like candy wrappers, flower bouquet wraps, or chip bags) when I mash it in my hand?
NO. Please do not include, as it is not currently acceptable for recycling.

It has labels or tape?
YES, but labels, tape, and adhesive strips SHOULD BE REMOVED prior to putting it in the recycling bin. The integrity of the bag isn't important—the recycler just wants the clean plastic.

It is thicker, stiff plastic like pet food bags or bedding bags (including anything with a zipper)?
NO. These are not the same type of plastic as what recyclers want, so DO NOT include.

If it says it's degradable or compostable?

NO. These bags cannot be placed in drop-off points. The recyclers reprocessing bags don't want the products they are making to degrade over time so these bags are not acceptable. These bags are generally translucent green, have the words compostable on them. They also a tree like arrow coming from a leaf and pointing back to the leaf as a symbol.

It is dirty, has crumbs, or is wet?
NO. Recyclers need the bags and film to be CLEAN and DRY. Please don't include dirty or wet bags, or any material that has food or other residues. If in doubt, throw it out!


What happens to my bags and wraps after they're recycled?

Plastic bags are recycled into many different products. Most bags and film are turned into composite lumber, but they can be reprocessed into small pellets or post-consumer resin, which can be used to make a variety of new products, such as new bags, pallets, containers, crates, and pipe. Watch this video to learn more about how your bags and wraps can become new composite lumber.
