    I like aluminum cans as well but I think it is more energy intense to melt them down and re-manufacture them compared to cleaning and refilling glass. It also has to be used to store products that are under pressure, most of a beer can’s strength comes from the pressure inside!

      Yeah, though aluminum also has the advantage of being orders of magnitude lighter, so you save a lot on fuel for shipping at every stage of the process. Plus a glass bottle can only be used as a bottle: recycled aluminum is more flexible.

      So it could easily tilt in favour of aluminum I think. BUt you’re right that it’s not clear-cut.
