Throwing it away after single use is madness.
My issue with this type of thinking is it assumes "transport cost <<< manufacturing cost" -- a decent assumption for a lot of goods throughout a lot of history, but just... not really true for lots of things in a modern supply chain.
The cost of moving the gown between users -- in the form of the user needing to give back the gown to the service, who must then clean it, inspect it, etc. -- may in fact be far higher than the cost of manufacturing a new gown and only needing your supply lines to be "one way".
Being mindful of how much trash we produce does not necessitate producing less (or more!) -- but merely balancing the pros and cons.
