Abstract

Polyhydroxyalkanoates (PHAs) are biopolymers, which can be used as a substitute for petrochemical plastics in diverse applications. However, these bioplastics are presently more costly than petrochemical plastics. Various researchers had investigated to exploit the use of economical waste streams derivative substrates. Waste frying oil is an ample cheap substrate which can be used without filtration in PHA production. Ralstonia eutropha is a handy organism for the production of PHA. Due to its similar physical properties to synthetic plastics, Polyhydroxyalkanoate (PHA) a biologically-synthesized plastic is attracting major interests in green material industries. Bioplastics are synthesized from renewable resources and they are degraded by aerobic microorganism to CO2 and H2O when disposed-off. For the commercialization of PHA; some important aspects like inexpensive carbon sources, selection of suitable bacterial strains, efficient fermentation and recovery processes should be taken into consideration.
