Abstract

Plastic pollution is a global problem that degrades the environment and subsequently kills animals. New research lines are
emerging to find highly biodegradable bioplastics or plastic compositions that are more ecologically friendly than present
ones. Bioplastic forms a rapidly growing class of polymeric materials that can be manufactured from vegetable oils and
starch and also by exploiting microorganisms. Microorganisms have the feature of producing different biopolymers like
polyhydroxyalkanoates (PHAs) naturally. These microorganisms can be utilized to develop strategies for using them as cell
factories. These biopolymers are accumulated inside the microorganisms as energy reserves of carbon. Extremophiles like
haloarchaea species show the production of considerable amounts of PHA, polyhydroxy butyrate, and polyhydroxy valerate.
Studies also suggest that microalgae and cyanobacteria are also the two promising sources of PHAs. This review is focusing
on the production of bioplastics from microalgae, summarizes the production of bioplastics from haloarchaea and followed by
covering the advantages of lignocellulosic fibers and lignin in bioplastics.
