| Summary: | Plastic products are utilized as packaging materials with numerous features including durability, strength, and low density in comparison to paper and glass. However, the accumulation of plastic would be a considerable pollution issue negatively affecting the ecosystem. This is because of its high resistance to degradation. Several researchers endeavored to manage the accumulation of plastic by devising processes such as incineration, recycling, or reuse. However, the disposal of highly toxic compounds, including hydrocyanic and hydrochloric acids, during incineration is a main associated issue. Realizing these points, manufacturing bioplastics instead of using plastic oil appears to be a competent option. Specifically, polyhydroxyalkanoate (PHA) is a well-known type of bioplastic that can be manufactured via fermentation using bacteria. In this review, the main basics of bioplastics are presented outlining the aspects of biodegradation as a sustainable industrial process compared to plastic. Specifically, this review intends to shape the synthesis of PHA from waste and wastewater sources. This includes the review of PHA structures, properties, industrial methods, and an intensive review of the feast-famine mechanism. Lastly, a critical evaluation of this industry, along with challenges and suggestions for improvements, is addressed.
