I clicked through on the link that the article said showed that bromine was impossible to recycle. The abstract says "Here we propose a catalytic strategy that enables the selective and mild-condition conversion of all organobromides present in wastes into renewed bromides for Br recycling. It employs Ullmann-type reactions enabled by inexpensive Cu(I), simple ligands and hydroxides in DMSO–H2O solvent. This strategy achieved >95% bromide yields at a temperature ≤120 °C for complex real-world Br-laden wastes."

I'm sure it would take a long time to make this process fit for mass bromine recycling, but it's a bit hard to take the rest of the article seriously.
