ABSTRACT
As the world is facing a Covid-19 pandemic, this virus teaches a lesson about the importance of on-site disinfection. On-site disinfection/sterilization with real-time monitoring of biomedical waste generated from the medical facilities is mandatory to prevent hospital-acquired infection (HAI). In this study, the life cycle assessment of two technologies, i.e., microwave (radiation-based) and autoclave (steam-based) were performed to summarize the inside-out evaluation of both technologies in terms of efficiency, efficacy, and cost-effectiveness. The results of disinfection efficacy indicated a log 10 reduction (almost 100%) in the vegetative load of microorganisms compared to the control, showing a similar level of disinfection efficacy of both strategies. Additionally, both technologies were compared on several parameters, and it was discovered that the autoclave uses more time and resources than the microwave. The total cost of an autoclave to the government is approximately double that of a microwave, while the operational cost of an autoclave is more than double that of a microwave. The findings from this study indicate that MACS may be used as a dry technique of biomedical disinfection, and its portability, tunability, and compactness make it a suitable alternative for biomedical disinfection and sterilization.
