I know they’re made from recyclable products, aluminium and paper, but they’re also an awkward combination of glossy paper glued to aluminium, which—last time I checked—were sent directly to landfill here.
Here’s the Tetra Pak website about recycling for Australia, where it goes on for a bit to vaguely avoid saying they go to landfill as the aluminium isn’t a sufficiently concentrated source, and nobody cares to reuse the low grad paper that could be reclaimed.
