What happens to the harmful chemicals in biodegradable plastic as it deteriorates?

    Plastic was once believed to be completely nonbiodegradable. However, a study funded by Nihon University was released in August 2009 confirming that although plastic does decompose, it yields harmful chemicals in the process, particularly into bodies of water. Because not 100 percent of the plastic used for recycling is reusable, and because plastic is only partially biodegradable, a few complex compounds are created and released into the environment that are not naturally found in nature and cannot be broken down. In long-term, low-temperature decomposition (as discussed in the 2009 study), these chemicals are identified as styrene monomer (SM), styrene dimer (SD) and styrene trimer (ST). Styrene is believed to be a human carcinogen.

    Plastic can also slowly release a dangerous toxin commonly known as BPA, and in recent years reusable water containers have changed their products to ensure that they do not contain BPA.
