Recycling symbols help consumers and waste processors identify what materials are recyclable and how to properly dispose of them. However, not all symbols guarantee recyclability, and confusion is common. This guide breaks down the most important recycling symbols and what they really mean.
1. The Mobius Loop (♻️)
- Meaning: This is the most recognizable recycling symbol.
- Indicates: That the item can be recycled, but not necessarily accepted everywhere.
- Variations:
- With a percentage inside (e.g. “70%”) → contains that much recycled content.
- Review: ✅ Useful, but misleading if people assume it means always recyclable.
2. Plastic Resin Identification Codes (1–7)
These numbers inside a triangle tell you the type of plastic.
| Code | Name | Common Use | Recyclable? | Review |
|---|---|---|---|---|
| ♳ 1 | PETE or PET | Bottles (soda, water), packaging | ✅ Yes (widely) | ♻️ Easy to recycle |
| ♴ 2 | HDPE | Milk jugs, detergent bottles | ✅ Yes (widely) | ♻️ Durable and accepted |
| ♵ 3 | PVC | Pipes, shrink wrap | 🚫 Rarely | ❌ Hard to recycle, often toxic |
| ♶ 4 | LDPE | Grocery bags, bread bags | ☑️ Sometimes | ♻️ Needs drop-off programs |
| ♷ 5 | PP | Yogurt cups, straws, bottle caps | ☑️ Growing | ♻️ Recyclable in some areas |
| ♸ 6 | PS (Polystyrene) | Foam cups, take-out containers | 🚫 Rarely | ❌ Often banned, pollutes |
| ♹ 7 | Other (PC, PLA) | Mixed plastics, bioplastics | 🚫 Hard | ❓ Varies widely |

- Don’t bag recyclables — keep loose in the bin.

- Don’t recycle wishfully — when in doubt, check before tossing.

FAQs
Are all items with the recycling symbol actually recyclable?
No. The symbol only suggests potential recyclability. Some items (especially plastics #3–#7) might require special facilities and are often rejected by local curbside recycling.
Is plastic with the number 7 recyclable?
Usually not. Code 7 is a mix of plastics (“Other”) and includes bioplastics and polycarbonates. Some municipalities accept them, but many don’t.
What is the “Green Dot” symbol? (•→•)
It means the manufacturer contributes to recycling programs financially (common in the EU).
⚠️ It does NOT mean the product is recyclable.
Are compostable items recyclable?
No. Compostable plastics (like PLA) should go to composting facilities, not the recycling bin. They contaminate the plastic stream.
Are pizza boxes recyclable?
Only if they’re clean. Greasy or food-stained boxes should be composted or trashed — the oil contaminates paper recycling.
Is glass always recyclable?
Yes, but check locally. Some programs don’t accept glass due to contamination or cost. Sort by color if requested (clear, green, brown).
How do I know if something is recyclable in my area?
Check your local recycling program’s website. Some areas offer apps or charts with accepted materials. The same symbol can mean different things depending on the location.
What does “widely recycled” mean on packaging?
It indicates that 60% or more communities in the country accept that item in curbside programs — a good sign for recyclability.
What should I do before recycling a container?
Rinse it to remove food residue.
Remove plastic film or caps (if not accepted).
Flatten cardboard boxes to save space.
