I would presume that anything plastic is sterilised and used again (presumably that is autoclaved) so I don't understand the need for a never-ending supply of PPE. If the medical profession can't sterilise used plastic then they will be adding hugely to an already massive environmental problem.
My daughter tells me they clean and re-use their goggles and visors, but have to throw away the aprons and gloves after every patient. She is seeing one patient after another, so that's an awful lot of plastic. I don't understand why they can't wash their gloved hands in a special soap, dry and go to the next patient. If the gloves are clean then why can't they be used again?
