However, when a plastic water bottle or plastic bag is placed in such a laboratory contraption, the microorganisms don’t begin to break down the material. Plastic is not a substance that is found in nature, and is therefore not capable of being broken down by microorganisms. That being said...

Animals who swallow plastic bags often suffer from intestinal obstructions, which typically lead to a long, slow, and painful death. Animals can also be poisoned by the chemicals used to create the bags or from chemicals that the plastic has absorbed while making its way through the environment...
It is also important that these alternative materials are able to biodegrade without the aid of a machine, which could generate more carbon emissions. And if it can decompose naturally, there is also the question of whether, in the time it takes to biodegrade, it causes problems with wildlife...
Even if made with recyclable or compostable materials, the stinky contents means disposable diapers go to the landfill where they will not biodegrade. And considering a single baby will probably go through between5,000-6,000disposable diapers before becoming potty trained, that’s a lot of waste...
—Does gasoline go bad? —Why doesn't plastic biodegrade? —How much trash is on the moon? There are hints of optimism elsewhere, too. In 2016, researchers discovered plastic-eating bacteria, and others have since identified polyethylene-munching worms (this beastie is a caterpillar of the gre...

Biodegradable packaging is typically made from organic materials and breaks down after use, whether in a home compost pile or a specialized facility.
ASTM D5511is the Standard Test Method for Determining Anaerobic Biodegradation of Plastic. ASTM D5511 is a shorter test, in a simulated laboratory condition and assumes long-term expected biodegradability timing based on short-term measures.
