The analysis and evaluation of the transfer of auxiliary facilities as a sustainable closure measure was carried out by comparing the transfer with conventional closure measures (as disassembly, dismantling, demolition, reconformation of the land, placement of organic soil and revegetation). This evaluation was performed using multicriteria analysis.
