    Abstract: In this study, influence of measures adopted to improve CDW management in Cantabria are evaluated based on results obtained from the indicator proposed, which track the evolution over time of management of this waste stream in the region and the degree of achievement of policy objectives. Apart from that, actions carried out are analysed compared with actions proposed in the Plan, giving as a result a global analysis of the situation of CDW management in Cantabria and its evolution along Regional Plan validity years. Results obtained displays a global improvement of the management of this waste stream in Cantabria thanks to measures adopted, from 0% CDW recycling in 2009 to reach near 90% of recycling in 2013. However, the lack of incentives and regulations to high-grade applications of recycled aggregates produces that resources obtained ended up in low-grade applications, having as a result downcycling instead of closing loops. All this information, is useful to emphasize shortcomings of the current management system, helping to propose actions needed from now on to improve total resources recovery of this waste stream. In conclusion, this study demonstrated the usefulness of Regional plans to evaluate the actual situation and to help decision making related to waste management, being the use of indicators helpful to study influence of measures or incentives in the final management of waste.

    Abstract: In this work, a comparative study of four different MCA methods; Weighted Summation, Regime, Electre II and Evamix; was performed by means its application to select optimal locations for C&DW management facilities in Cantabria, Spain. Results obtained ar e analyzed in order to assess if the method applied may provide different results with the same data, which may lead to a non-objective identification of the best alternative. Besides, analyses of the sensitivity and uncertainty of the results have been also carried out in order to investigate the robustness of the results obtained. Uncertainty of input data includes uncertainty in data selection and uncertainty in measurement values, whereas uncertainty in the model itself includes model structure and parameters. The main results show that the application of more than one MCA method to verify the results is highly recommended; mainly to locate CDW recycling facilities due to this decision involves a large investment that must be insured for a long time.

    Abstract: The European Commission considers Construction and Demolition Waste (CDW) as a priority waste stream due to the large amounts generated. Cantabria is a northern Spanish region where new CDW legislation (BOC, 2010) has been developed and, as a consequence, a network of CDW distribution with recycling facilities and transfer stations needs to be properly located. This work deals with this objective by means of an optimization model that takes into account not only economical and environmental criteria but social aspects of the region as well. The proposed final network includes three facilities: two recycling plants and one transfer station. The municipality where each facility must be located, the capacity of them and the distribution network of the waste is also determined.

    Abstract: The aim of this paper is the identification of the location and capacity of the transfer stations and processing plants and the corresponding management network by means of an optimization model that minimizes: (i) medium transportation distance (ii) total management costs (installation, operation and landfill) with and without administrative predefined areas. The model is formulated as MILP problem where the binary variables represent the presence or not of management facilities at a location. GAMS is used as a high-level modelling system for the resolution of the mathematical programs. The obtained results show very different C&DW treatment networks with total cost ranging from 3.53 to 4.34 mill €/y and medium transport distance ranging from 14.77 to 24.10 km.

    Abstract: In this work the methodology developed by European Environmental Agency has been used as a starting point in developing a set of Specific Indicators on the primary sector waste. Eleven indicators have been developed to evaluate the generation and management of forest, agricultural, livestock and food industry waste. These indicators allow not only monitoring the primary sector waste management, but also they highlight the precarious situation in relation to knowledge of actions undertaken in the sector in relation to their waste and with the information flows. Therefore, in this paper the analysis of difficulties for management the available information has been carried out.

    Abstract: In this work, a methodology based in Multicriteria Analysis with the aim of locating C&DW recycling facilities has been developed and applied to a real-life case in Cantabria, a northern Spanish region. The region has been divided in geographical areas in which different alternative locations for recycling facilities have been assessed. One of these geographical areas was evaluated and a compromise solution based on economic, environmental and social criteria has been provided by Definite 3.0 MCA software. Four multicriteria analysis methods: Evamix (EV), Weighted Summation (WS), Electre II (E2) and Regime (REG) have been performed in order to obtain the most suitable locations. Analyses of the sensitivity and uncertainty of the results have been also carried out in order to investigate the robustness of the solutions obtained. Therefore, the main findings of this research have showed the robustness and reliability of the application of MCA methodology for C&DW site location

    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 methodology for the quantification of C&DW has been developed and applied to the case study in Cantabria, a northern Spanish region. 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 belongs 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.

    Abstract: En el Punto Focal de Residuos de Cantabria, proyecto en el cual se engloba el presente estudio, se gestiona la información relativa a residuos en base a tres sistemas de indicadores, los indicadores Básicos, Específicos y Trasversales; correspondientes a distintos niveles de concreción. El sistema de indicadores Básico permite una evaluación comparada de los resultados obtenidos en distintos contextos espaciales. En primer lugar se realiza la recogida sistemática de la información a nivel Nacional y se procesa dicha información a través del sistema de Indicadores Básicos, formado por los siguientes indicadores: Generación de RSU, Reciclaje de papel/cartón, Recogida de vidrio, Reciclaje de envases, Producción de lodos de depuración y Generación de residuos peligrosos. Se procede posteriormente a la comparación, analizando la evolución temporal y el valor del indicador con respecto a la media nacional, de las Comunidades Autónomas. Representando finalmente los resultados obtenidos mediante un sistema de información geográfica. Entre los principales resultados se obtiene que Cantabria presenta valores superiores a la media Nacional para la tasa de generación de RSU, reciclaje de envases y papel/cartón y la recogida de vidrio para el último año de estudio. Siendo por otro lado, la Comunidad en la cual se produce una menor cantidad de lodos por habitante al depurar las aguas. En el caso de los Residuos Peligrosos, destaca la escasez de datos en las Comunidades Autónomas, siendo difícil la interpretación de los resultados.

    Abstract: Los Planes Sectoriales aprobados mediante el Decreto 15/2010 son: el Plan Sectorial de Residuos Municipales, el Plan Sectorial de Residuos Industriales, Residuos de Construcción y Demolición y Minería, el Plan Sectorial de Residuos Especiales y el Plan Sectorial de Residuos del Sector Primario, Sanitario y Veterinario. Cada uno de los Planes está dividido en diferentes programas, de prevención y minimización, reutilización, recogida, reciclaje, valorización energética y eliminación, en los cuales se proponen objetivos y líneas de acción para llevarlos a cabo. Para poder realizar el seguimiento de dichos objetivos, se propone gestionar la información a través de cuatro sistemas de indicadores, cada uno de ellos relacionado con los objetivos propuestos en cada Plan Sectorial correspondiente. Para desarrollar cada indicador, es necesario conocer cada una de las variables de las que va a constar, los datos necesarios para su cálculo y se localizan las fuentes que puedan proporcionar dichos datos. Una vez organizada la información por fuente de datos, se procede a la petición de datos mediante formularios, para desarrollar finalmente los indicadores.

    Abstract: The increasing care about the environment has influenced the more and more frequent need to take environmental criteria into account in the decision making with others historically further developed like the economic, technological or social criteria. This combination of factors complicates the quantitative analysis of alternatives that the decision maker has to confronting. Furthermore there are many environmental factors difficult to make a comparison and to quantify. In order to be able to study the influence of all these factors, the Multicriteria Analysis Methods are used. The Multicriteria Analysis (MCA) is a mathematical tool which evaluates different alternatives using a sequence of criteria previously decided. This tool is used in a wide range of decision problems, including the environmental management. The advantages of using this kind of tools are: a) the decision is structured into manageable sub components; b) directly involves the stakeholders and the negotiation among the actors implicated is easier; c) a great diversity of problems can be included and; d) it can act as a process of nonstop learning. The main objective of this work is to intensify in the knowledge of the tool through its application to a case study: Municipal Solid Waste Management (MSWM) in north Spain. The following tasks have been carried out: i) a bibliographic review of the MCA methods used for the decision making in all kind of issues (see figure 1); ii) selection of the methods MCA more utilized on environmental issues; iii) influence of the different selected MCA methods and the number of alternatives and criteria used in each MCA method on study case (MSWM).
