State-Of-The-Art Review on Efficacy of Various Disinfection Techniques of the Abandoned PPE Waste

The current pandemic generates plastic waste from the medical field, mainly consisting of polystyrene, polypropylene, polyethylene terephthalate, nylon, and polyethylene. COVID-19 outbreak has become a universal health hazard, leading to severe human respiratory tract infections via droplets, infected palms, or surfaces. Personal protection equipment (PPE) must be worn at all times to avoid contracting COVID, which creates a huge problem for the PPE supply chain made of single-use plastic. The greatest challenge is to minimize the decontaminated PPE waste generated with the help of the reuse and recycling of PPEs so that the abandoned PPE waste can be minimized. Because new research has recently improved the reliability of reprocessing technologies, reusing PPE could be a viable short-term solution to the COVID-19 epidemic. These include vaporized hydrogen peroxide disinfecting techniques, ultraviolet light disinfecting techniques, thermal disinfecting techniques like pyrolysis, a microwave technique, and many more. The study's main objective is to generate a list of all the relevant literature on various PPE sterilizing processes in order to assist readers in determining their best options.
