I worked in an environment where use of PPE was part of our everyday routine. Much if the stuff was disposable ‘one use’ equipment, but that’s not to say it wasn't feasible to clean and re- use the items if we'd been in a situation where supplies were limited.
With all due respect to those from a non- technical background, it’s not easy to grasp this concept unless you've had first- hand experience (particularly if you’re a journalist and/or you have a conflicting political agenda). Same argument applied to disposable laboratory items, they could've been cleaned for re- use but it was more cost- effective to bin them after one use.
