Abstract:
Degradation of plastic polymers takes decades, making them a serious global issue due to their non-biodegradable solid waste status. Comparing biodegradation to other degrading processes, it is the most efficient and optimal approach for plastic decomposition due to its non-polluting mechanism, eco-friendliness, and affordability. The biodegradation of synthetic plastic is a gradual process that is aided by ambient conditions and naturally occurring microbial species. By secreting enzymes that break down plastics, bacteria and fungus contribute significantly to the biodegradation of plastics. High molecular weight polymers are broken down into low molecular weight polymers by the enzyme's oxidation or hydrolysis, which produces functional groups that increase the hydrophilicity of the polymer. For this reason, plastics deteriorate in a couple of days. This study presents the most recent research on the different types of fungi and bacteria that break down polyvinyl chloride (PVC), as well as the roles played by insects and the mechanism underlying the process.
