Polyhydroxyalkanoates (PHAs) belong to an interesting family of biopolymers produced by
a number of microorganisms. They are polyesters metabolically synthesized by microbes as
an energy storage medium in a manner very similar to fats and oils in higher organisms.
As bio-based and totally biodegradable thermoplastics, PHAs have a potential of being
used as a replacement material for conventional petroleum-based plastics. A new class
of PHA copolymers, initially developed by a research team of P&G and later transferred to
Danimer Scientific for commercialization, have successfully overcome the traditional cost
and performance limitations of earlier bio-based resins and is now making a steady inroad
to become a mainstream plastic.
