Coca-Cola is to test a paper bottle as part of
a longer-term bid to eliminate plastic from its
packaging entirely.
The prototype is made by a Danish company
from an extra-strong paper shell
that still contains a thin plastic liner.
But the goal is to create a 100% recyclable,
plastic-free bottle capable of preventing
gas escaping from carbonated drinks.]
I assume you can remove the plastic liner
so you recycle the rest?
