Recycling is contaminated when it contains material the receiving collection or process cannot accept. That can mean the wrong item, leftover food, liquids or unsuitable packaging.
What causes a problem?
Examples include food left in containers, non-container glass mixed with bottles, and ordinary rubbish hidden inside a bag of recycling. Different services have different accepted lists, so a material accepted elsewhere may still be wrong for your bin.
Recycle Now’s contamination guidance explains material differences and preparation. Contamination can lead to rejection or extra sorting; it does not follow that one small error inevitably condemns an entire lorry.
If you receive a rejection tag
Read what the crew identified and how the council says to present the bin again. Remove an ordinary misplaced item only if it is safe. Do not reach into sharp, chemical or damaged-battery waste; ask for appropriate instructions.
Keep the tag or reference if you need clarification. A return visit is not guaranteed after correction, so follow the council’s next-collection procedure.
Avoid common mix-ups
- Separate drinking glass and ovenware from bottle/jar glass.
- Use the correct route for batteries.
- Check food-soiled pizza boxes.
- Follow explicit rules for bags and shredded paper.
“Not recyclable here” does not always mean general waste. Sharps and hazardous items need suitable separate disposal.
Will I be fined for a mistake?
Enforcement depends on jurisdiction and circumstances. Do not treat a rejected bin as proof of a fixed penalty. England’s household-bin guidance describes a specific process and restrictions.
Should I bag everything to keep it clean?
Only if the collection requires bags. Otherwise use the service’s approved loose-material or container method.
