Storing our samples of oxo-degradable bags in the same container as our starch-based biodegradable bags started the process of degradation. Whereas samples stored as we normally do on our sample rails were intact. It looks like the starch which decomposes may have triggered the biodegradation process. It was an unintentional and uncontrolled experiment but the results can be seen for themselves. We are often asked- does it degrade and how long does it take? The samples have been around for a 2- 3 years.
