Thanks, the second link looks very helpful and gave me further ideas on how to try to work backwards to get an idea of the recycling processing costs: find spot prices of raw/intermediates that come from the process produced by companies with the black box recycling processes while trying to find those companies volume sold/processed over time (ideally they would process more when the underlying market is more expensive).
