Biodegradable Polymers in the Environment: Are They Really Biodegradable?
Biodegradable polymers in the environment represent a cause for concern, depending how one defines and establishes the degree of biodegradation. In this paper, I will define biodegradable polymers, explain why they are used, how the degree of biodegradability is estimated and what the environmental implications are for incomplete biodegradation. Tests available are not yet totally satisfactory and further development needs are indicated. Some possible approaches are raised.
