Since this article is focused on evaluating disassembly technologies for EOL EVBs, we have already shown the outcome of our stakeholder selection within the methods section (“Stakeholder selection”), which provided the basis for our further methodological steps. Therefore, in the following subsections, we concentrate on the results from the criteria identification, criteria weighting, and technology evaluation process.
Evaluation criteria
A corpus of 16 EOL EVB disassembly technology evaluation criteria was identified through 65 expert interviews with relevant stakeholders (see “Criteria identification” section):
-
Adaptability.
-
Flexibility.
-
Automatability.
-
Capex.
(Operational expenditure)
The identified criteria, along with the experts attesting to their presence, are presented in Table D.1. It can be seen from Table D.1 that we consolidated the outcome of the expert interviews into the overarching 16 criteria. This consolidation step was conducted since we performed a delphi panel with a benchmark of disassembly technologies among those criteria later in this study. The higher the number of criteria, the more complex the delphi panel gets, so we wanted to reduce and consolidate the criteria based on the expert interviews. The consolidation process was conducted and iteratively discussed by the authors, who categorically grouped similar criteria. Table D.1 explicitly delineates the criteria mentioned by the respective expert. Furthermore, Table D.1 details the elements from the interviews that were ultimately consolidated into the 16 categories of criteria, thereby ensuring a transparent process from the initial interview contents to the final criteria employed in this study.
