Bioplastics are biodegradable polymers that are made by bacterial cells, whose molecules have biochemical properties similar to petrochemical polymers as they are concentrated inside intracellular granules as a carbon and energy sources, and which then degrade in the environment as they get exposed to light. Bioplastics have desirable biodegradable and renewable qualities, sustainable qualities as well as alternatives to petroleum-based plastics, and is used due to much of its biodegradability and durability. Due to their vast usefulness, Poly Hydroxy Alkanoate (PHAs) and their derivatives are used in many different sectors, PHAs are the most biodegradable bioplastics found throughout the world. These polymers are generated by microorganisms through metabolic pathways that start with hydroxy-acyl-A and end with different types of acyl-A. Bioplastic polymers have chemical characteristics that differ in structural and physical properties which also differ due to the source of their polymerization microorganisms.
