Breaking up is not enough.

The short answer

Oxo-biodegradable plastic is ordinary plastic with additives that help it break apart under certain conditions. Breaking apart is not the same as composting.

Small fragments can still be a problem. A tidy-sounding word does not make a tidy outcome.

Compostable products need specific composting evidence. Oxo-degradable products have been restricted in European single-use plastic rules.

For caddy liners, the useful question is still route and certification.
