Pullulan

Example:While pullulan is natural, synthetic polymers like plastic are used widely in manufacturing but may have a different environmental impact.

Definition:A polymer made from artificial or man-made materials, often involving petrochemicals.

Example:Conventional plastics are non-biodegradable, which is in contrast to the potentially biodegradable properties of pullulan.

Definition:Not capable of being broken down or decomposed, often referring to substances that can persist in the environment for a long time.
