Used masks are contaminated and are considered medical waste and cannot be disposed of like ordinary garbage, but require special treatment according to medical waste. Masks used in daily life may not have the chance of being contaminated. If you need to dispose of used masks at home by yourself, you can cover the masks with a separate bag and put it in the non-recyclables when throwing away garbage. For other items that may be contaminated, it is also recommended that they be separated into separate plastic bags, tied tightly at the mouth, and placed in the non-recyclable trash.
