Hi Alice,
Thanks for your question.
While polystyrene is technically a plastic, it can’t be recycled through your kerbside recycling bin because it's often made with additional materials and is difficult to process in its expanded form.
If the item is no longer reusable and can’t be donated to a local charity store, it should be placed in your garbage bin.
Keep in mind that items must fit inside your garbage bin with the lid closed for collection. If it doesn’t fit, you’ll need to take it to a nearby waste facility for disposal.
To find suitable drop-off locations or waste facilities near you, just search for “polystyrene” on the Recycle Mate app or website—it will guide you to local options based on your area.
Hope this helps!
Thanks,
Murphy
