Glass as is too heavy. Penn and Teller did a bull shit on recycling. Only aluminum is good for consumer packaging wrt recycling.

Most aluminum packaging has plastic liner. Which has to be burned away in most cases.

Glass works if you bottle and reuse locally. Unfortunately infrastructure for this is long gone in the US.

It burns away when the metal is melted. Not having glass recycling infrastructure supports p&t's point.
