Extending biopolyesters circularity by using natural stabilizers: A review on the potential of polyphenols to enhance Poly(hydroxyalkanoates) thermal stability while preserving its biodegradability

PHAs are polyesters synthesized by micro-organisms as an energy reserve from renewable, and possibly non-food, feedstock. They non-toxic, biocompatible quickly biodegradable in different natural environments, ensuring not to pollute jeopardize our ecosystems unlike conventional plastics. good candidates replace plastics such polypropylene for their functional properties during the usage stage of life cycle. However, expanding eco-efficiency circularity adding cycles, reuse or recycling, life-cycle requires improve thermal stability mechanical properties. Here we offer discuss on how improving thermomechanical while preserving crucial biodegradability. The review focuses a well-known type stabilizer, polyphenols impacts PHAs’ It has mainly been concluded that presence polyphenols, at certain amount, contributes improvement physical-chemical PHAs, whereas there is no evidence have inhibitory effect biodegradation PHAs.
