    Cans.
    Cans are actually recyclable containers, that fix most of the environmental problems of plastic bottles.

    They’ve had resealable “bottle like” cans for a decade or more already.

    Fountain drinks can use the same CO2 they already have, to pressurize cans of concentrate to pump the syrup to the fountain head.

      Not entirely. All cans currently made (at least for the US) have a super thin plastic liner to help the drink avoid taking on too much of a metallic taste.

      There are multiple YouTubes out there that will show you what happens when you dissolve an aluminum can; the dissolution process removes the aluminum and leaves the plastic liner.

        Not sure what you mean by dissolving. As far as so know aluminum gets melted down. Any plastic, inks, or other impurities get burned off generally.

            Yah, that’s not how they are recycled. That gets burned off by the temps required to melt the aluminum.

                It’s not. It’s a thin plastic film. One that doesn’t get into the environment at nearly the rate, since the aluminum is actually worth recycling.

                    I think you may have an unworkable concept of what “solving” the plastic problem means, when you can’t tell the difference between a film and a bottle. Both of which have largely phased out BPA already.

              I, nor the poster you replied to, never mentioned recycling. Your starting to put things into the discussion that was never there.

                It does seem that way.
                I guess I’m not sure what problem you’re talking about.

      Aluminium recycling/melting however needs a lot of energy, which again is often generated from non-renewable sources. So even cans are bad for the environment.

        That’s a temporary problem. One solved by the renewable energy transition already underway.
