Reusable syringes if you autoclaved and chemically sterilized to the point even prions were distroyed wouldn't be the worst thing.

I prefer glass bottles and they are far easier to recycle. (Not that my cities waste collection bothers to do so and I have to go out of to do so).

The issue with both is what happens when someone screws up the cleaning and sterilization (or flat out skips it).

New material has never been exposed to anything dangerous, so dangerous contamination never needs to be removed.

It’s a big reason why plastic is so rarely recycled anywhere that it touches food or goes into someone’s body.
