Comment on Why would the NA beer industry standardize on a bottle shape that's grotesquely inconvenient, topples with minimal force, and doubles the required volume to ship?

There’s no plastic in an aluminum can. Both glass and aluminum are almost totally recycled into their base materials. Aluminum is lighter to transport to and from the recycling facility.

The inside of the can is lined by spray coating an epoxy lacquer or polymer to protect the aluminum from being corroded by acidic contents such as carbonated beverages and imparting a metallic taste to the beverage

Guess it depends on your definition of “plastic” and if someone would colloquially refer to an epoxy lining as plastic. Not here to debate word meanings but there is definitely a liner inside aluminum cans.

What I was referring to was the BPA lining traditionally found in cans: https://www.beeradvocate.com/articles/15869/bisphenol-pale-ale-should-you-be-worried-about-the-bpa-in-your-beer-can/

Looking it up now, it looks like there are multiple alternative linings which are being phased in and/or proposed, but every can still has some sort of lining, whether an epoxy or other similar material to protect the contents of the can from the aluminum or vice versa.

EDIT: whether or not this lining outweighs the additional transport and processing costs of glass (remelting/shaping glass is much more energy intensive than aluminum reporcessing as I understand it) was the question I was proposing and one I don't have an answer for.

What aluminum cans are you getting that don’t have a plastic lining?
