Multi-criteria decision-making methods for the optimal location of construction and demolition waste (C&DW) recycling facilities

Multi-criteria analysis (MCA) is a powerful tool that has frequently been used to solve environmental decision-making problems, because it integrates different perspectives of the stakeholders involved. This chapter first includes an overview of different decision-making tools, to focus on MCA methods and their main characteristics. Some examples of the application of this tool for locating waste treatment facilities are included. In addition, the required steps to apply the MCA-based methodology for the selection of adequate construction and demolition waste (C&DW) recycling facility locations are discussed. Finally, the applicability of this methodology is demonstrated with a case study in the northern Spanish region of Cantabria, in which the location of a recycling facility in the most populated area was evaluated: the steps followed in this case study are explained to increase understanding of this methodology.
