Summary

This paper is not about microplastics. It reviews the biodegradable biopolymer PHBV (poly(3-hydroxybutyrate-co-3-hydroxyvalerate)), covering its production, properties, degradation behavior, and applications in various sectors. While PHBV is studied as a potential biodegradable alternative to conventional plastics, this paper focuses on polymer science and materials engineering rather than microplastic pollution.

This review presents a comprehensive update of the biopolymer poly(3-hydroxybutyrate-<i>co</i>-3-hydroxyvalerate) (PHBV), emphasizing its production, properties, and applications. The overall biosynthesis pathway of PHBV is explored in detail, highlighting recent advances in production techniques. The inherent physicochemical properties of PHBV, along with its degradation behavior, are discussed in detail. This review also explores various blends and composites of PHBV, demonstrating their potential for a range of applications. Finally, the versatility of PHBV-based materials in multiple sectors is examined, emphasizing their increasing importance in the field of biodegradable polymers.
