1.1 What is a biopolymer?

The classification of biopolymers depends on their origin:

• bio-sourced" polymers of renewable origin;

• polymers of non-renewable origin, known as "petro-sourced".

Biodegradable polymers can be obtained from both categories. For example, there are biodegradable "petro-sourced" polymers.

However, this definition may vary from one trade to another. In the scientific community, the notion of biopolymers may be "restricted" to the family with a renewable origin. It is often broader for the plastics processing community, which also considers biodegradable (petro-sourced) polymers as belonging to the biopolymer family. All...
