“…Even heating at 1550–2000 K results in the destruction of infectious agents carried by the CW. At 3000K, highly resistant cytotoxic drugs are broken into simple substances ( Cai and Du, 2020 ). In the plasma pyrolysis technique, CW's inorganic waste gets converted to neutral slag and metal remains.…”

COVID-19 has led to the enormous rise of medical wastes throughout the world, and these have mainly been generated from hospitals, clinics, and other healthcare establishments. This creates an additional challenge in medical waste management, particularly in developing countries. Improper managing of medical waste may have serious public health issues and a significant impact on the environment. There are currently three disinfection technologies, namely incineration, chemical, and physical, that are available to treat COVID-19 medical waste (CMW). This study focuses on thermochemical process, particularly the pyrolysis process to treat medical waste. Pyrolysis is a process that utilizes the instability of organic components in medical waste to convert it into valuable products. Besides, the technique is environmentally friendly, more efficient, requires less landfill capacity, causes lower pollution, and cost-effective. The current pandemic situation generates a high amount of plastic medical waste, which has components like polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET) and nylon (N). These plastic wastes can be converted into valuable energy products like oil, gas and char through the pyrolysis process. This study provides detailed information about CMW handling, treatments, valuable product generations (biofuels), and proper discharge into the open environment.

“…Plasma processing uses an electrical current that is discharged through an inert gas to ionize and in turn causes an electric arc to create high temperatures of up to 1700 degrees Celsius which leads to the decomposition of the compounds [ 73 ]. This process van be applied to both organic and inorganic materials and can be applied to highly cytotoxic drugs as well.…”

Healthcare is a rapidly growing industry as medical treatments become more sophisticated, more in demand due to increasing incidence of chronic disease and more widely available worldwide. This booming industry is also creating more waste than ever before and, as such, there is a growing need to treat and dispose of this waste. Healthcare waste (HCW) disposal includes a multitude of disposal methods, including incineration, landfilling and chemical treatments. These rudimentary methods and their growing use present their own problems that negatively impact both the environment and, in turn, damage public health, thus contributing to a global healthcare crisis. The aim of this review was to examine the current HCW disposal methods in place and the harmful effects they have on the environment and on public health. The findings accumulated in this review demonstrate a heavy reliance on basic, low tech HCW disposal techniques and uncovered the negative impacts of these methods. There is a notable lack of employment of “greener” HCW disposal methods on a largescale due to cost, access and feasibility. Despite innovations in HCW disposal, there is no scalable, global green solution at present. Further, the review highlights that global health consequences of HCW disposal methods often differ depending on how developed the country is.

“…The effectiveness of this expensive technique depends on the power of the instrumentation since the higher energy output, facilitates the temperature conversion. This method is appropriate for all forms of MW since no harmful products are released, the end volume is significantly reduced, and the heat energy that is produced can be recycled [132][133][134].…”

The importance of medical waste management has grown during the COVID-19 pandemic because of the increase in medical waste quantity and the significant dangers of these highly infected wastes for human health and the environment. This innovative review focuses on the possibility of materials, gas/liquid/solid fuels, thermal energy, and electric power production from medical waste fractions. Appropriate and promising treatment/disposal technologies, such as (i) acid hydrolysis, (ii) acid/enzymatic hydrolysis, (iii) anaerobic digestion, (vi) autoclaving, (v) enzymatic oxidation, (vi) hydrothermal carbonization/treatment, (vii) incineration/steam heat recovery system, (viii) pyrolysis/Rankine cycle, (ix) rotary kiln treatment, (x) microwave/steam sterilization, (xi) plasma gasification/melting, (xii) sulfonation, (xiii) batch reactor thermal cracking, and (xiv) torrefaction, were investigated. The medical waste generation data were collected according to numerous researchers from various countries, and divided into gross medical waste and hazardous medical waste. Moreover, the medical wastes were separated into categories and types according to the international literature and the medical waste fractions’ percentages were estimated. The capability of the examined medical waste treatment technologies to produce energy, fuels, and materials, and eliminate the medical waste management problem, was very promising with regard to the near future.
