The results of life cycle sustainability assessment (LCSA) with respect to multiple technologies were widely adapted and compared by decision makers when a selection should be made based on sustainable impacts of those options. However, since each alternative has its advantages and disadvantages, none of alternatives can be proved to be the best by observing from the results of LCSA, in most cases. Therefore, multicriteria decision making (MCDM) methods are used to prioritize options or to select the best one. The combination of LCSA and MCDM improves the data quality and provides a direct decision making result based on all-rounded sustainability assessment. This chapter summarizes MCDM methods used in competitive case studies based on LCSA results. A group Z-number best worst method (group ZBWM) combined with the goal programming method was adapted to analyze a case study regarding waste oil management technologies selection. The results and discussions are illustrated afterward.
