Recycling feels like the responsible thing to do — and it is worth doing well — but it comes with an honest caveat most guides skip: collection is not the same as conversion. Getting something into the recycling bin doesn't guarantee it's recycled; a lot is lost to contamination, sorting limits and markets. That's exactly why recycling is only the fourth of the 5 Rs, not the first. Still, doing it right genuinely matters — here's how.
The golden rules
Get these four right and you'll recycle better than most:
- Empty, rinse and dry. Food residue contaminates whole batches; a quick rinse is enough.
- Keep it loose. Don't bag your recycling (unless your service asks) — bagged items are often sent straight to landfill.
- Don't wishcycle. When in doubt, leave it out (more on this below).
- Check your local rules. Recycling is local — what's accepted varies by council and facility, so your area's list is the final word over any general guide.
What's usually recyclable
Widely accepted in most kerbside programs:
- Paper and cardboard — clean and dry (flatten boxes).
- Glass bottles and jars — rinsed.
- Metal — aluminium and steel cans, clean.
- Rigid plastics #1 (PET) and #2 (HDPE) — bottles, jugs and tubs, in most areas.
What usually isn't (even though people try)
These are the common "wishcycling" mistakes:
- Soft/film plastic — bags, wrappers, cling film (take clean film to store drop-off points instead).
- Black plastic — most sorting machines can't detect it.
- Greasy or food-soiled paper — pizza boxes, used napkins (compost these).
- "Compostable" or "biodegradable" plastic — it contaminates recycling and rarely composts at home either; see compostable vs biodegradable.
- Small items — bottle caps loose, straws, coffee pods — they fall through the sorting.
- Drink cartons (Tetra Pak), crisp packets, and mixed-material packaging — check locally; often not accepted.
What the recycling numbers mean
The 1–7 symbol on plastics is the resin type, not a promise it's recyclable:
- #1 PET and #2 HDPE — most commonly recycled.
- #5 PP — increasingly accepted.
- #3 PVC, #6 PS (polystyrene), #7 other — rarely recycled kerbside.
So the number tells you what a plastic is, not whether your council takes it — always cross-check the local list. (Full breakdown: what the recycling numbers mean, and the common recycling myths worth unlearning.)
Why wishcycling backfires
Tossing something in "just in case" feels harmless, but the wrong items contaminate the batch, jam machinery, and can send otherwise-good recycling to landfill. A clean, correctly-sorted bin recycles more than an optimistic, contaminated one. When unsure, bin it or find the right drop-off — don't gamble.
Hard-to-recycle items
For things kerbside won't take — soft plastics, batteries, electronics, toothpaste tubes — look for store take-back schemes and specialist programs (like TerraCycle). Better still, reduce these items so there's less to chase.
The real lesson: recycle less
The most effective recyclers are the people who have the least to recycle. And be wary of green marketing on packaging: our guide to spotting greenwashing helps. Refusing and reducing packaging (see reduce plastic waste), reusing what you own, and composting food scraps all shrink the bin before recycling even enters the picture. New to all this?

Frequently asked questions
Do I need to rinse recycling? Yes — a quick rinse to remove food residue. Dirty items can contaminate a whole batch and get it sent to landfill.
Should I put recycling in a bag? No, keep it loose in the bin unless your local service specifically asks for bags. Bagged recyclables are frequently rejected.
What do the numbers on plastic mean? They identify the plastic type (resin code 1–7), not whether it's recyclable. #1 and #2 are most widely recycled; always check your local list.
What is wishcycling? Putting non-recyclable items in the bin hoping they'll be recycled. It contaminates good material and does more harm than good — when in doubt, leave it out.
The bottom line
Recycle properly — empty, rinse, dry, keep it loose, and follow your local rules — but hold it in perspective: it's the safety net, not the solution. Skip the wishcycling, learn the few things your area actually takes, and put your real effort into creating less to recycle in the first place.
