Still the point stands that you can reuse glass a lot than plastic before you have to recycle it. (Glass up to 50 times and PET up to 25 times.) Transport pollution is a solvable problem, but they definitely require more energy to get transported.

And the point is still that reusable works no matter how it gets produced and recycled, since it avoids the production of a lot of new bottles.

Bringing your own stuff is definitely the best way, yes. That would require special filling stations, which I don’t see coming anytime soon. I’ve only seen tests for bringing your own container with dry and pourable stuff, but that may require standardized containers for weighing if I remember correctly. At least in supermarkets.
