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.
In Nordics a large part of household waste is incinerated for energy, I don't have recent numbers but 50% already in 2015 in Finland and Sweden. In addition some part is of course recycled/composted (glass, paper, metal, bio). Landfills get just a tiny slice.
