The term bioplastic can be confusing because it refers to biosourced and/or biodegradable materials with different properties.
There are 2 classification criteria:
The origin of the resource
from which they are produced for biosourced bioplastics.
End-of-life
for biodegradable and compostable bioplastics.
Classification of the main bioplastics
Biobased polymers are not necessarily biodegradable. Biodegradable polymers are not necessarily biosourced.
