“…These variations could be attributed to the large number of medical products, such as protective suits, face masks, glasses needles, scalpels, and knives. The presence of Na and K in MBAs probably originates from medicine, physiological saline, blood-stained cotton, wound-dressing materials and body fluid in medical waste, which has been previously reported ( Bakkali et al, 2013 ; Shen et al, 2019 ). Some products in medical waste could increase the content of metals in MBAs.…”

“…Chlorine-containing polymers such as polyvinyl chloride syringes in the hospital were also incinerated as medical wastes. In addition, because chlorinated disinfectant was applied in the hospital to eliminate the COVID-19 virus, a large amount of Cl was applied to disposable medical gear, such as protective suits ( Bakkali et al, 2013 ; Shen et al, 2019 ). The presence of the other anions might be caused by the application of related medical chemicals.…”

“…Incineration reduces 80–95% of the volume of solid waste; 118 , 119 thus, this would be the better option during the pandemic in controlling infectious diseases and mitigating environmental pollution; however, the risk of spreading infectious diseases during transportation remains. 120 The mobile incineration process with heat and energy recovery would be a potential solution to reduce risks during transportation. However, the composition of MSW may have played an essential role in selecting waste management technologies.…”

Impacts of COVID-19 Outbreak on the Municipal Solid Waste Management: Now and beyond the Pandemic

The COVID-19 pandemic disrupted the municipal essential services, including municipal solid waste (MSW) management. This study has reviewed the literature on MSW and solid medical waste (SMW) management systems, waste management initiatives specific to this pandemic, as well as their impacts now and beyond. Waste segregation and separate treatment of waste streams play important roles in reducing the environmental, health, and social impacts of waste and waste management. The global warming potential of MSW and SMW were found to be varied from −0.64 to 520 kg CO 2 equiv/tonne and −52.1 to 3730 kg CO 2 equiv/tonne, respectively, which widely depend on the sterilization and disposal processes. Similarly, MSW and SMW disposal costs varied from 90 to $242/tonne and 12 to $1530.0/tonne, respectively. Various changes made to waste collection and management because of the COVID-19 pandemic affected waste segregation and recycling. Since the start of the pandemic, various sectors, including the food, waste management, and healthcare sectors, relied on the increased use of single-use plastics to prevent transmission of COVID-19. An environmentally friendly alternative (biodegradable/compostable) to widely used single-use plastics is desired for easing waste management problems. Although various initiatives are underway to manage growing volumes of MSW and SMW, while controlling the spreading of infectious diseases, the movable grate incineration technology coupled with an adequate disinfection process presents a potential solution in managing the COVID-19 waste challenges. The proper disinfection method and technological choices can mitigate the risk of spreading infections and can improve the waste management system's sustainability, especially the contaminated waste.

“…Therefore, landfi lls are not the simple method used for medical waste disposal. In contrast, approximately 90% of hazardous medical waste is treated using the incineration method 3,4 . The incineration of hazardous wastes has many advantages, such as signifi cant volume reduction (approximately 90-95%), resource recovery 5 , complete destruction of harmful bacteria and non-fl ammable components.…”

In this study, air flow controlled incinerator (AFCI) was used to treat medical solid waste in Vietnam. The experiment was conducted with solid waste samples that was weighed approximately 2.1–3.3 kg/h and had moisture content of 2.8–11.7%. The results showed that an increase in the airflow rate during the drying process accelerated the combustion time by 10–20%, and the optimal airflow rate was 1.1 m/s. The combustion time varied from 0–45 min. The highest temperatures recorded in the drying chamber, carbonisation chamber and combustion chamber after 25–35 min of operation were varied from 195°C, 775°C and 1275°C, respectively. The temperature of the stack was from 33–68°C after the treatment by the wet scrubber using 20% NaOH solution. The combustion capacity was 77.3–87.5%. The experimental results revealed the AFCI process advantages including low operation cost and suitability for treating hazardous waste on a small scale.
