Waste management has been a great problem globally for at least five decades. Some of thedeveloped countries could initiated certain processes to benefit from the waste. In this way,countries could both got rid of waste and they could exploit from it and used waste in differentways such as heating, recycling, etc. The situation became even worse during the coronavirusdisease 2019 (COVID-19) pandemic. The COVID-19 pandemic has altered global wastegeneration dynamics and thus became one of the most important issue for all countries for nowand for future. Actually, healthcare waste is all the waste generated by healthcare facilities,medical laboratories and biomedical research facilities, as well as waste from minor orscattered sources. However, during the pandemic, masks, increased amounts of contaminatedwaste including gloves, other protective equipment, and along with non-contaminatedmaterials, many types of additional medical and hazardous waste are produced. Thesecontaminated wastes not only dirts the environment, but also may cause the pandemic spread.The inadequacies and inefficiencies of current waste management system to deal with theincreased dependence on plastic could aggravate its mismanagement and leakage into theenvironment, thus triggering a new environmental crisis. Therefore, this study will highlightsthe possible effects of COVID-19 on the waste management and environment.
