How do I dispose of a used liner?

Not down the toilet

Liners should not be flushed down the toilet as they have a plastic backing on them (which is not biodegradable) and they may also block the plumbing system. Schools and public toilets usually provide special sanitary bins, so place your used liners in there (wrap it in toilet paper first, as the sticky side may get stuck to the bin door). If you can’t find one of these special bins (you probably won’t have one at home), don’t fret, just wrap the liner in toilet paper (or put it in a bag) and then pop it in the bin.
