Abstract

Polyhydroxyalkanoates (PHAs) are biopolymersobtained via bacterial fermentation of organicresidue and have a fundamental role to play infuture circular economies. Within this family,poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)(PHBHHx) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P3HB4HB) have attractedscientific attention due to their ductile responseand processability
