What Can and Can't Be Recycled in Glasgow

Recycling contamination is a real problem in Glasgow. When the wrong items end up in the blue bin, entire loads can be rejected and sent to landfill instead. Here's a definitive guide to getting it right.

YES: Put These in Your Blue Bin

Paper and cardboard (flattened), plastic bottles (with lids on), plastic food tubs and trays, food tins and drink cans, empty aerosol cans, aluminium foil (scrunched into a ball), Tetra Paks and cartons.

NO: Keep These Out

Food waste, nappies, black bags, soft plastics (cling film, carrier bags, crisp packets), polystyrene, broken glass, textiles, wood, garden waste, electrical items, batteries.

Common Mistakes

Pizza boxes: only if clean. Greasy pizza boxes should go in general waste. Shredded paper: put it in a paper bag first, loose shreds jam the sorting machinery. Plastic film: the soft plastic on ready meals isn't recyclable in your blue bin (some supermarkets collect it separately). Coffee cups: the plastic lining means they can't be recycled in standard facilities.

Do You Need to Rinse? And Do Lids Come Off?

Rinse, but don't scrub. The point is to get rid of food residue that would rot in the bin and spoil the paper it's sitting against, not to return the container to showroom condition. A quick swill under a running tap is plenty, and cold water is fine. Lids are the more confusing part: plastic bottle tops should stay screwed on, because loose ones are too small for the sorting machinery and drop out of the process, while metal lids from glass jars come off and go in the blue bin separately from the jar itself, which belongs in the purple one.

Soft Plastics

Major supermarkets including Tesco, Sainsbury's, Asda, and Co-op now have front-of-store collection points for soft plastics: bread bags, crisp packets, cling film, and plastic wrapping. This is worth using as these materials make up a significant portion of household waste. The rough test is the scrunch: if it stays balled up when you squeeze it and doesn't spring back, it's a soft plastic and belongs at the supermarket rather than in your blue bin.

Cardboard: When There's Too Much for the Bin

Flatten everything, because an unflattened box fills a quarter of a bin on its own. If you've had a delivery-heavy month or you've just moved in, the blue bin will not cope, and the answer is not to pile boxes beside it in the hope they get taken. Loose cardboard next to a bin frequently isn't collected, and in wind it ends up as litter that gets traced back to your address. Bundle and tie the excess and take it to a recycling centre, or if the volume is genuinely large, from a shop fit-out or a house move, get it collected in one go.

What Happens When a Load Is Contaminated

It isn't just your bin that's affected. Kerbside recycling is tipped into a lorry that serves a whole round, and from there into a sorting facility. One black bag of general waste in that load can be enough for the batch to be downgraded or rejected, which means the paper and cans that everybody else on the street sorted correctly go to landfill anyway. That's why crews will leave a visibly contaminated bin rather than tip it, and why the tag matters more than it looks.

Recycling Symbols on Packaging

The symbols on packaging are less helpful than they appear, because several of them describe what the material could be in principle rather than what Glasgow actually collects. The Mobius loop with a number tells you the type of plastic, not whether your council takes it. The green dot does not mean recyclable at all. Our guide to recycling symbols goes through what each one really means. When the packaging and this page disagree, go with this page, because collection is decided locally.

Making Recycling Easier

Keep a small caddy or bag next to your main bin for recyclables, because the moment sorting requires a walk it stops happening. Rinse food containers before they go in: a quick rinse is enough, they don't need to be spotless. Flatten cardboard boxes to save space in your bin. If you're unsure about a single item, the safer default is general waste, since one wrong item in the blue bin can cost the whole load while one recyclable item in the green bin costs only that item.

Businesses and busy households that produce a lot of recyclable waste often do better with a larger bin collected on their own timetable. We supply commercial bins in Rutherglen, commercial bins in Burnside and commercial bins in Croftfoot, and one-off loads can go through waste removal in Burnside.
