According to the principle of prudence, from the perspective of protecting the public's life and health to the maximum, it is recommended to put the used masks separately in sealed bags such as plastic bags. In cities such as Shanghai that implement waste sorting, put sealed bags in "hazardous waste" bins, "said Du Huanzheng, a professor at the School of Environment and Sustainable Development of Tongji University cited by the Science and Technology Daily.

In some cities that do not have stricter regulations on waste classification and treatment, Tao Xiaoqing, director of the interventional vascular department of Weihai Haida Hospital, suggested that mask waste at home should be put in bags to avoid secondary pollution.
