Blends of Starch and PE are NOT truly biodegradable. Traditionally these materials contain less than 20% starch and the balance is PE.

The starch is consumed by the microbes, however that leaves 80% PE which only fragments and litters the environment. There is no scientific data to suggest that a substantial amount of the PE is ever biodegraded.

To learn more about this issue and to find truly biodegradable/compostable materials, I suggest that you visit the website of the International Biodegradable Products Inst. (www.bpiworld.org). There you can find relevant tests and standards, ones that are recognized and used around the world.

Adding starch to PE does not make it biodegradable.
