Best option for disposal:
Place in your red lid rubbish bin.
Otherwise:
If the lid is white and definitely labelled as plastic 1, 2 or 5 it can be separated from the cup section and placed in your recycling bin. All other plastic types must be placed in the rubbish bin.
Coffee lids with a home compostable AS 5810 symbol on them can be placed in your home compost.
Do not place coffee lids with any compost symbols on in your green lid garden waste bin.
