      Ok, glass is acceptable. They’re both technically infinitely recyclable (unlike plastic).

      Although it is easier to get aluminum back to a usable state. You can for instance melt down a whole vat of aluminum and reprocess the whole lot of it. But a similar vat of mixed glass, you can melt it down but it’s hard to get all the color out of a mix of clear brown and green bottles, and you really want a clear base product.
