ELI5: How do medical facilities (hospitals, out patients, plastic surgery facilities, etc) dispose of things like body parts that are amputated, or skin that has been removed etc?

Often it's incinerated. Maybe the places which don't do it themselves ship the red hazmat bags to a commercial facility which does the job. 

I think there are provisions for if a patient wants to retain their tissue, but it's not common except for miscarriage.
