Abstract
Disposal and management of construction and demolition waste (C&Dw) is a substantial part in the different phases of the construction process and accounts for 35% of the waste disposed of in landfills worldwide [Kabirifar et al., 2020], adressing the environmental impact of such waste as a global concern. Meanwhile, the treatment of waste and raw materials involves considerations of their economic and social impact. The End of Waste (EoW) concept of the EU Directive 2008/98/EC and its subsequent amendment 2018/851, directs waste to a recovery operation including recycling and preparation for re-use and priorities the management of the waste stream due to the large quantities produced. Within the construction process, the choices faced by the different actors involved in the recycling macro-issue are part of a decision-making environment that can be defined as complex: it concerns different situations, falls on different actors and, potentially, can include infinite evaluation criteria. This suggests the possibility that multicriteria evaluation techniques may be a useful tool for decision-making. In this regard, a preliminary analysis of the existing literature has allowed the identification of two decision- making macro-environments: a. the definition of input design choices for the future recyclability of materials and artefacts (field defined in the paper as input); b. the choice for the efficiency of C&Dw management or for the tracking of the waste flow (a field defined in the paper as output). The contribution intends to return some multicriteria applications aimed at the efficiency of the disposal and recycling processes of recyclable construction and demolition waste, providing an overview of the possible supports for this phase of the decision-making process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
