Plastics used almost every manufacturing industry are resist to biodegradation. Their persistence in soil for a long time has become a major concern in terms of the environment. This promotes many investigators to search for replacement of non-biodegradable by degradable plastics. Polyhydroxyalkanoates (PHAs), known as a biodegradable plastic produced by bacteria, have received increasing attention due to the difficulties in disposal of plastics. In recent years, researchers have focused on the processes to increase PHA production which involve in biological phosphorus removal (BPR). Normally, BPR can be achieved through anaerobic- aerobic cycling by a group of bacteria known as polyphosphateaccumulating organisms (PAOs). PHA is stored within the PAO as carbon polymers under anaerobic conditions by taking up volatile fatty acids (VFAs), further it is used as energy source and phosphorus uptake under aerobic conditions. The aim of this review is to discuss recent advances in PHA production from wastewaters and parameters effecting PHA production efficiency.
