Polyhydroxyalkanoates production from waste biomass

Abstract

Polyhydroxyalkanoates (PHAs) is a group of biopolymers that are extensively researched for such purpose due to the biocompatibility with mammal tissue and similar properties with conventional plastic. However, commercialization of PHA is impended by its high total production cost, which half of it are from the cost of pure carbon source feedstock. Thus, cheap and sustainable feedstocks are preferred where waste materials from various industries are looked into. This paper will highlight recent studies done on PHA production by utilizing crop and agro waste material and review its potential as alternative feedstock.
