Abstract:

Plastics are the repeating units of monomers that may occur naturally as well as be made synthetically. Eventually, the improper use, production, and management of plastics result in innumerable negative results on the environment. About 51 trillion microplastic wastes fill the ocean. The accumulation of plastic waste results in the disturbance of ocean life. These plastic contaminants not only harm aquatic life but also block the digestive tract of fish. The conventional method for the decomposition of plastics is Thermal decomposition. As a result of thermal decomposition, mendacious gases like CO and chlorine are released, adversely affecting the environment. Most synthetic plastics are non-biodegradable; they cannot be degraded naturally to cope with the issue; several types of enzymes are used. The direct enzymatic activity is very useful as the microorganisms are used to degrade the plastics. Biodegradation of plastics by microorganisms can be Aerobic, which utilizes oxygen as an electron acceptor; Anaerobic, which utilizes carbon dioxide as an electron acceptor to break down plastics polymers. Pyrolysis is also the emerging method to degrade plastics by providing High temperatures along with anaerobic conditions. This study aims to cover all the ways in which plastic degradation has minimal effects on the environment as well as public health. The finding of this study ensures that enzymatic degradation and pyrolysis both are the best techniques to decompose plastic polymers as the decomposition of the polymers results in the production of useful products. However, these methods faced serious economic and significant technical challenges. Further research is needed to identify more sustainable methods for plastic waste decomposition.
