This is true, and when people talk about recycling aluminium cans they’re actually only talking about recycling the aluminium in those cans. The liner is not recycled.
However it’s a relatively small amount of plastic, and burning it while melting the metal does prevent it from ending up as plastic pollution. So aluminium cans are still better than non-recycled plastic packaging.
There are probably more remakes/remasters that do use AI upscaling for background assets than those that don’t.
