Hi Ethan,
Thank you for your recycling enquiry. It was a great question and has been added to Recycle Mate’s item library.
Silicone baking mats, ice cube trays, and similar items cannot be disposed of in your kerbside recycling bin. The kerbside system is designed to handle everyday packaging waste like bottles, jars, and containers, so other household items cannot be processed.
If your silicone baking items are in good condition and suitable for resale, use Recycle Mate to find a charity shop or nearby location accepting donations.
If the items are not in good condition, they will need to be placed in your general waste bin.
I hope this helps. Thank you for reaching out—every question helps us build better recycling solutions in Australia.
