Poly(butylene succinate) (PBS) is a bio-based and biodegradable aliphatic polyester with good thermal and mechanical properties comparable to commodity plastics. The addi- tion of cellulose filler reinforces the polymer matrix, thus, increasing mechanical, barrier and biodegradation properties. PBS/cellulose composites are versatile materials with potential applications in packaging, agricultural, automotive, and biomedical fields. The selection of cellulose filler from recycled cellulose to nanocellulose can be used to develop materials for specific applications.
