Cellulose esters are produced from cellulose in wood. They are therefore partially biobased, but are generally not biodegradable (except as regenerated pulp).
Depending on the chemical modifications made, different materials can be obtained, such as cellulose acetate or cellulose proprionate. This family of materials has a high transparency and good mechanical and thermal properties. It is used, for example, for injection moulding processes or in the machining of plates for the manufacture of the branch of glasses.
