Plastic Recycling: What's Not Recyclable
Globally, approximately 91% of plastic waste is non-recycled, according to recent environmental data. While some of this is technically "recyclable" in theory, the vast majority ends up in landfills, incinerators, or the natural environment due to economic and technical limitations.
Types of Non-Recyclable Plastics
Plastics are generally categorized by Resin Identification Codes (#1 through #7). Most curbside programs only accept #1 and #2.
- Resin Code #3 (PVC): Found in credit cards, plumbing pipes, and some cling wraps. It contains toxins that can contaminate the recycling stream.
- Resin Code #6 (Polystyrene/Styrofoam): Used for disposable coffee cups, egg cartons, and packing peanuts. It is lightweight, bulky, and difficult to process economically.
- Resin Code #7 (Other/Miscellaneous): This is a "catch-all" category for mixed plastics, like BPA, polycarbonate, and bio-plastics. Because they are a blend, they cannot be easily separated and processed.
- Black Plastics: Many automated sorting facilities use infrared sensors to identify plastics; because black plastic absorbs the light, the machines often fail to "see" it, sending it to the landfill instead.
Common Household Items That Are Typically Non-Recyclable
- Even if an item has a "chasing arrows" symbol, it may not be accepted at your local facility due to its shape or composition:
- Flexible Packaging: Chip bags, snack wrappers, and juice pouches. These are often "composite materials"—laminates of plastic, aluminum, and paper that are impossible to pull apart.
- Small Items: Plastic straws, stirrers, and cutlery. These are too small for sorting machines and often fall through the grates or jam the equipment.
- Plastic Film & Bags: Grocery bags and bubble wrap. These are "tanglers" that wrap around the spinning gears of recycling machines, forcing entire plants to shut down for manual cleaning.
- Contaminated Items: Takeout containers or "clamshells" heavily soiled with food or grease.
The 2026 Outlook
As of early 2026, the global recycling market is facing significant pressure. Recent reports indicate a "pullback" in several sectors due to the high cost of mechanical recycling compared to the low price of "virgin" (new) plastic. While new technologies like chemical recycling and Mixed Waste Sorting (MWS) are being deployed to capture more of these materials, the current global recycling rate remains below 10%.
