Estimation of Construction and Demolition Waste (C&DW) Generation and Multicriteria Analysis of C&DW Management Alternatives: A Case Study in Spain

Abstract

Construction and demolition waste (C&DW) constitutes a priority waste stream in the European waste strategy due to its large volume and its high recycling and reuse potential. Directive 2008/98/EC on waste, stresses the need of quantify the waste stream and to improve the material recovery efficiency of C&DW in the European Union. Designing a suitable network of facilities involves an adequate knowledge of the inputs to material recovery facilities. In this work, a two-step methodology for the quantification and waste management analysis of C&DW has been developed and applied to the case study in Cantabria, a northern Spanish region. In the first step, the quantification of C&DW was calculated by means of an equation which combines municipal licenses and ratios of waste per unit area of construction, demolition and renovation. The selected ratios for the study case in Cantabria belong to four northern Spanish regions, and they were developed by two associations of architects, one technological institute and by the regional legislation recently developed in the region. In the second step, the waste management assessment for C&DW was carry out throw the development of a multicriteria-based methodology for decision-making in order to select the most suitable management alternative. The application of the methodology to the case study in Cantabria has been performed using four multicriteria analysis methods: Evamix (EV), Weighted Summation (WS), Electre II (E2) and Regime (REG). Analyses of the sensitivity of the results have been also carried out in order to investigate the robustness of the solutions obtained in the decision making process.

ELECTRE: A comprehensive literature review on methodologies and applications

“…The proposed methodology was applied to a case study in Greece, where 22 alternative locations were compared on nine criteria. Coronado et al (2011) developed a two-step procedure for estimating the quantity of construction and demolition waste (CDW) generated and evaluating management alternatives for handling CDW. The methodology was applied in a case study in for Cantabria in Spain.…”

“…Similarly, the rate reached 85 % in Japan by 2000 and also more than 50 % in Australia [20]. It is necessary to promote the recycling rate because it is the most effective way to solve problems of CW after generation.…”

“…Quantification of waste in building energy rehabilitation works I. INTRODUCCIÓN os residuos de construcción y demolición (RCD) representan uno de los principales flujos a nivel internacional, a pesar de que la crisis económica ha incidido directamente en el sector de la construcción, provocando un descenso del volumen de RCD generados en la última década (Coronado et al, 2011). Los últimos datos publicados por Eurostat, sitúan a los RCD en alrededor del 30% sobre la total de los residuos sólidos generados a nivel europeo y nacional (Eurostat, 2017).…”
