ิbiopolymer is naturally occurring polymers that are found in all living
organisms. The use of biopolymers has less adverse impact
on our environment compared to using fossil fuel based
commodity plastics [4]. During the last two decades,
considerable attempts have been made to develop biodegradable
polymers and composites [3]. Aliphatic polyesters
such as polylactic acid (PLA), polycaprolactone (PCL), poly
(3-hydroxybutyrate) (PHB) and polyglycolic acid (PGA)
represent important biodegradable polymers, which are
now finding commercial applications in combination with
bio-based materials [5]. PLA, is a linear aliphatic thermoplastic
polyester, produced from renewable resources,
which has gained much attention in both research and
applications [6,7]. This polymer is produced either by ring
