“…PHAs produced by microalgae and cyanobacteria have been considered a good substitute for petroleum-based plastics because of their similar mechanical properties [ 54 , 55 ]. The presence of PHB molecules in microalgae cell makes the microalgae-based polymers biodegradable in nature [ 56 ]. According to Madadi et al [ 57 ], PHAs have been found in the range of 1–25% dry weight in some cyanobacteria [ 57 ].…”

Microalgae and cyanobacteria are photosynthetic microorganisms’ sources of renewable biomass that can be used for bioplastic production. These microorganisms have high growth rates, and contrary to other feedstocks, such as land crops, they do not require arable land. In addition, they can be used as feedstock for bioplastic production while not competing with food sources (e.g., corn, wheat, and soy protein). In this study, we review the macromolecules from microalgae and cyanobacteria that can serve for the production of bioplastics, including starch and glycogen, polyhydroxyalkanoates (PHAs), cellulose, polylactic acid (PLA), and triacylglycerols (TAGs). In addition, we focus on the cultivation of microalgae and cyanobacteria for wastewater treatment. This approach would allow reducing nutrient supply for biomass production while treating wastewater. Thus, the combination of wastewater treatment and the production of biomass that can serve as feedstock for bioplastic production is discussed. The comprehensive information provided in this communication would expand the scope of interdisciplinary and translational research.
