What Happens If a Recycling Bin Is Contaminated?

Putting the wrong items in a recycling bin is called contamination — and it has serious consequences. Even a small amount of food, plastic, or rubbish in a recycling bin can cause an entire truckload to be sent to landfill. Here’s what contamination means, why it matters, and how to avoid it.

What Is Recycling Contamination?

Recycling contamination happens when non-recyclable materials are mixed into recycling bins. This includes food scraps, plastic bags, textiles, or any items that don’t belong in that particular bin stream.

🚫 Consequences of Contamination

  • Entire loads sent to landfill – If contamination levels are too high, recycling facilities may reject the whole truckload.

  • Increased costs – Sorting and disposal fees rise when recycling is contaminated, and councils or businesses often pay more.

  • Damage to recycling equipment – Plastic bags, soft plastics, and other wrong items can jam sorting machines.

  • Lower recycling quality – Contamination reduces the value of recovered materials, making them harder to reuse.

  • Environmental impact – Recyclables that could have been reused end up wasted in landfill.

Common Contaminants

  • Food scraps and liquids

  • Plastic bags and soft plastics (unless collected separately)

  • Nappies or sanitary products

  • Clothing and textiles

  • Electronics, batteries, and hazardous waste

  • Polystyrene foam and coffee cups

Household Tips to Prevent Contamination

  • Rinse containers before putting them in the recycling bin.

  • Keep items loose—never bag recyclables.

  • Check local council rules for what belongs in each bin.

  • When in doubt, leave it out—better to place a questionable item in general waste than risk contaminating the whole bin.

Business Tips

  • Provide clear signage on bins to show staff what can and can’t go in.

  • Run staff training sessions on correct recycling practices.

  • Pair recycling bins with general waste bins to reduce “wishcycling” (putting items in recycling in the hope they’re accepted).

  • Schedule regular bin checks to ensure streams are clean.
