Evaluating WEEE recycling innovation strategies with interacting sustainability-related criteria

Evaluating innovation strategies plays an essential role for supporting sustainable development of the waste electrical and electronic equipment (WEEE) recycling industry. This requires the incorporation of the sustainability concept into the strategy evaluation process, which becomes complicated when sustainability-related evaluation criteria have complementary and substitutive interactions. This paper proposes a novel framework to facilitate systematic identification of sustainability-related criteria by integrating the triple-bottom-line (TBL) principle of sustainability and the model of benefits, opportunities, costs, and risks (BOCR). A capacity-based multicriteria decision making (MCDM) approach is developed to evaluate innovation strategies with respect to interacting sustainability-related criteria. Equipped with a new weighting model for interacting criteria on a multi-level hierarchy, the approach can obtain an overall contribution value for each innovation strategy. To illustrate the BOCR-TBL framework and the capacity-based MCDM approach, an empirical study on an innovation strategy evaluation problem of an Australian WEEE recycling company is conducted. This paper makes conceptual and methodological contributions to sustainability and MCDM research and contributes to the WEEE recycling industry by providing a structured methodology for innovation strategy evaluation.
