How to destroy expired school masks?

It should be destroyed centrally and uniformly.

Set up a special trash can. Main roads, dormitories, canteens, classrooms and other key places. Add a special garbage can for discarded masks on campus, and mark the words "garbage can for discarded masks", and put plastic garbage bags in the garbage can.

Do a good job of classification. The discarded masks collected by the school doctor's office and temporary medical observation points are disposed of according to the standard of medical waste, and the discarded masks collected in other places on campus are disposed of according to other domestic garbage.
