Recycling contamination happens when incorrect, dirty or hazardous items are placed with materials intended for recycling. A contaminated household bin may be left unemptied, and contamination collected with a wider load can reduce the amount that is successfully recycled.
Quick answer: remove items your council does not accept, empty food and liquid from packaging, keep paper and card dry, and never place batteries or electrical equipment in ordinary recycling.
What counts as contamination
Common examples include food waste, nappies, black bags, textiles, electrical items, batteries, ceramics and glassware that is not packaging. The exact list varies because councils use different collection and sorting systems.
Packaging does not need to be spotless, but significant food or liquid can spread onto paper and card. Put heavily soiled material in the route specified by your council.
Why councils may reject a bin
Collection crews often make a visual check before emptying containers. A tag or sticker may identify the problem. Removing the incorrect item does not always guarantee a return visit, so check the council’s missed or rejected-bin policy.
Batteries and electrical items create an additional fire risk when crushed in collection vehicles or sorting equipment. Use designated take-back and recycling routes.
How to prevent another rejection
Use your council’s current list rather than relying on bin colour. Empty containers, keep recyclable material loose unless instructed otherwise, close the lid and avoid overfilling.
If several households share bins, ask the landlord, managing agent or council for clearer labels and report repeated misuse through the appropriate local service.
