7 recycling mistakes that get whole bins rejected in the UK

When a recycling crew slaps a red tag on your bin and leaves it at the kerb, the reason is usually contamination — the wrong things in the right bin. It's not just pedantry: a badly contaminated load can be rejected at the sorting plant, sending an entire lorry's worth of carefully sorted recycling to landfill or incineration. Here are the mistakes that cause it, in rough order of how common they are.

The seven offenders

• 1. Plastic bags and soft plastic. Carrier bags, bread bags, crisp packets and cling film jam the sorting machinery. Never bag your recycling — tip it in loose. Many supermarkets now take soft plastics at front-of-store collection points.
• 2. Food residue. A half-full yoghurt pot or oily jar can spoil the paper and card around it. Quick rinse, shake, done — items don't need to be spotless, just empty and roughly clean.
• 3. Nappies and sanitary products. Genuinely one of the most common items found in recycling, and never recyclable. General waste, always.
• 4. Wishcycling. Putting something in the recycling "just in case" — toys, coat hangers, electrical cables, crockery — does more harm than binning it. If you're not sure your council takes it, check before you chuck.
• 5. Greasy pizza boxes. Cardboard is recyclable; card soaked in grease and cheese isn't. Tear off the clean lid for recycling and put the greasy base in general waste (or the food caddy, where councils accept it torn up).
• 6. Broken glass and Pyrex. Most kerbside schemes only want glass bottles and jars. Drinking glasses, ovenware and window glass melt at different temperatures and ruin the batch — bottle banks or general waste instead.
• 7. Batteries and vapes. These don't just contaminate — they cause fires in bin lorries and sorting plants. Every supermarket and most tips have battery collection points; vapes go back to the retailer under WEEE rules.

The pump, the lid and the film

Some everyday items are recyclable with a twist. Trigger sprays and pump dispensers often need the pump removed. Plastic bottles should be crushed with the lid screwed back on (loose lids fall through the sorting screens). And the plastic film over meat trays, plus the absorbent pad underneath, is general waste even when the tray itself is fine. When in doubt, the Recycle Now locator or your council's A–Z list gives a definitive answer in seconds.

A 30-second habit that fixes most of it

Almost all contamination comes from one moment: standing at the bin, unsure, guessing. Replace the guess with a glance at the label — most packaging now carries "recycle" or "do not recycle" logos — and keep a small bag by the back door for the things that need a supermarket or tip trip. Two bins, one habit, and your recycling goes from red-tagged to reliable.

Getting the right stuff in the right bin is half the battle; getting the bin out on the right day is the other. BinMinder reminds you the evening before every collection — free, matched to your address.
