Biodegradable PBS, PBSA, and PBAT Based Systems

For many decades, plastics have been important in daily life. Nevertheless, considering the environmental issues such as pollution associated with non-biodegradable plastics, it is extremely important to seek alternative plastic materials that can mitigate these issues. Poly (butylene succinate) (PBS), poly (butylene succinate-co-adipate) (PBSA), and poly (butylene adipate-co-terephthalate) (PBAT) are among other biodegradable plastics, which are considered a feasible alternative for the most widely used non-biodegradable plastics. These materials show excellent flexibility, impact resistance, processability, and biodegradability, which make them suitable for flexible packaging, mulch films, shrink wraps, biomedical, and many others. This chapter provides a critical overview of the synthesis, processing strategies, and application of PBS, PBSA, and PBAT in various application fields. The chapter further provides, among other things, an overview of the recyclability and degradation of PBS, PBSA, and PBAT in different media.
