To go in the recycling bin:
✅ PLASTIC LIDS need to have the recycling symbol with the numbers 1, 2 or 5 AND be bigger than a credit card.
✅ METAL LIDS need to be ferrous (which means they can be picked up by the sorting magnets), OR they need to be bigger than a credit card.

Let's look at the lids in this picture:
❌Hot chocolate canister lid (bigger than a credit card but has the number 4 in a triangle, which is not accepted).
❌ Wine bottle top (Smaller than a credit card, and since it's aluminium it isn't magnetic and the machines won't pick it up)
✅ Jam jar lid (big enough AND magnetic)
❌ Orange juice jug lid (has the number 4 on it, which is not accepted, and it's too small)
❌ Laundry detergent lid (big enough, but I can't see a number in a triangle. When in doubt, leave it out.)
✅ Beer bottle cap (it may be tiny, but it's ferrous so will be snatched up by the magnet on the sorting line)
