We’ve all stood by the kitchen bin, holding an empty package, whispering to ourselves: “Can this go in the recycling?”

With different councils enforcing different rules across the UK, recycling can feel like a high-stakes guessing game. When in doubt, many of us practice “wishcycling”—tossing something into the recycling bin hoping for the best. Unfortunately, a single contaminated item can cause an entire batch of recycling to be rejected.

Let’s clear up the confusion once and for all. Here are 10 tricky items you might be throwing into the wrong bin, and what you should actually do with them.

1. Greasy Pizza Boxes

• The Myth: Cardboard is recyclable, so the whole box goes in.

• The Reality: No. While clean cardboard is great for recycling, grease, cheese, and food residue ruin paper fibres and contaminate whole loads at the recycling plant.

• What to do: Tear off any clean top lids and recycle them. Cut away or compost heavily greased bottom sections (or put them in general waste if composting isn’t an option).

2. Soft Plastics & Crisp Packets

• The Myth: If it’s plastic, it goes in the home recycling bin.

• The Reality: No. Most UK council kerbside collections still do not accept flexible plastics like crisp packets, bread bags, film lids, or bubble wrap.

• What to do: Save them up and drop them off at soft plastic recycling collection points found at most major UK supermarkets (like Tesco, Sainsbury’s, and Co-op).

3. Receipts (Thermal Paper)

• The Myth: They are made of paper, so they go in paper recycling.

• The Reality: No. Most modern receipts are printed on thermal paper coated with chemicals like BPA or BPS. These chemicals contaminate the recycling paper pulp.

• What to do: Throw them in your general household waste.

4. Broken Glassware (Drinking Glasses & Pyrex)

• The Myth: Glass is glass—jam jars and wine bottles belong with drinking glasses.

• The Reality: No. Drinking glasses, Pyrex dishes, window panes, and mirrors are manufactured with different chemical compositions and melting points than glass bottles and jars. They ruin glass-sorting machines.

• What to do: Wrap them safely and place them in general waste, or take them to a local household waste recycling centre (tip) if they accept specialised glass.

5. Coffee Pods (Aluminium & Plastic)

• The Myth: They are small, so they’ll get sorted out later.

• The Reality: No. Standard kerbside sorting facilities cannot process small items like coffee pods; they fall through the machinery gaps or clog systems.

• What to do: Use dedicated free recycling schemes provided by brands like Nespresso or Podback, which offer collection bags or drop-off points.

6. Black Plastic Food Trays

• The Myth: Plastic trays are plastic, so they count as packaging.

• The Reality: It depends, but mostly no. Historically, optical sorting machines at recycling plants couldn’t “see” black pigment, meaning they were sent to landfill. While some UK councils now accept them, many still don’t.

• What to do: Check your local council’s website guidelines. When shopping, opt for clear or light-coloured plastic packaging whenever possible.

7. Toothpaste Tubes

• The Myth: They feel like soft plastic/metal mix, so they can’t be recycled.

• The Reality: Traditionally yes, but changing. Most traditional tubes are made of mixed plastics and aluminium layers.

• What to do: Standard kerbside bins usually reject them, but many UK pharmacies and large supermarkets now host specific terrycling drop-off bins for dental care products.

8. Wet Wipes & Baby Wipes

• The Myth: Some say “flushable” or “biodegradable,” so they must be eco-friendly waste.

• The Reality: Absolute no. Even “biodegradable” wipes do not break down fast enough in wastewater systems and clog drains or cause fatbergs. They certainly don’t belong in dry recycling.

• What to do: Always bin them in general waste (or switch to washable cloths!).

9. Aerosol Cans (Deodorant & Hairspray)

• The Myth: They are made of metal, so they shouldn’t go in normal waste.

• The Reality: Yes, you can recycle them! Many people assume pressurised cans are dangerous or prohibited.

• What to do: Make sure they are completely empty (don’t puncture or crush them), remove the plastic cap if required by your council, and place them in your dry recycling bin.

10. Envelopes with Plastic Windows

• The Myth: The plastic window ruins the whole envelope.

• The Reality: False. Modern recycling machinery easily filters out the thin plastic film during the pulping process.

• What to do: Feel free to drop junk mail and window envelopes straight into your paper recycling bin without manually ripping out the plastic windows!
