Item Kubik: Open building approach for the construction of an unique experimental facility aimed to improve energy efficiency in buildings(2011) Chica, José A.; Apraiz, Inés; Elguezabal, Peru; Rrips, Marc O.; Sánchez, Victor; Tellado, Borja; SG; Tecnalia Research & Innovation; ECOEFICIENCIA DE PRODUCTOS DE CONSTRUCCIÓN; EDIFICACIÓN DE ENERGÍA POSITIVA; DIGITAL ENERGYKUBIK is aimed to the development of new concepts, products and services to improve the energy efficiency of buildings. The main characteristic of KUBIK is the capability to built realistic scenarios to analyse the energy efficiency obtained from the holistic interaction of the constructive solution for the envelope, the intelligent management of the climatisation and lighting systems and the supply from renewable energy sources. The R&D infrastructure consists of a building able to provide up to 500 m2 distributed in an underground floor, a ground floor and up to two storeys; the main dimensions are 10,00 m. width x 10,00 m. length x 10,00 meter high (plus and underground floor 3,00 m. depth). The supply of energy is based on the combination of conventional and renewable energy (geothermic, solar and wind). In addition, the building is equipped with a monitoring and control system which provides the necessary information for the R&D activities. KUBIK's main structure provides an experimental, adaptable and reconfigurable infrastructure to create the indoor environments to analyse and to allow the assembly of the constructive solutions for the envelope, floors and partitions which performance must to be assessed under realistic conditions.Item Nuevo método para el diseño optimizado de plantas semi-automatizadas de tratamiento de RAEE: Caso de TV y monitores(2010-10) Rentería-Bilbao, Arantxa; Álvarez-De Los Mozos, Esther; Pérez-Larrazábal, Jose; Del Pozo-Rojo, Dionisio; Medical Technologies; Tecnalia Research & Innovation; SGWaste coming from electric and electronic appliances is an increasing environmental problem. Their present recycling and reuse ratio are far from the targets defined in the European Directive for "Waste from Electrical and Electronic Equipment", WEEE, which tries to reduce the waste going to landfills. This research proposes a new method for selection and design of automated and semi-automated operations of a recycling plant for electronic appliances. An improved recycling of the obtained materials is expected, with a more profitable process for small or medium enterprises. An example of its applicability is proposed, focused on the separation of the materials of TVs and monitors. Because of the difficult reuse of glass coming from the cathode ray tubes, a specific solution is proposed. Economic, legal and technical issues concerning the level of the automation applied to a recycling line are studied, covering from the full automation of all the disassembling tasks, to a manual dismantling. This knowhow is used by the proposed method as the input to a decision support system for optimization purposes. The parameters used by this system are: previous expertise of recycling companies, WEEE regulations and economic aspects (materials pricing, recycling costs, etc.). The simulation of the solution has been analyzed, with an economical assessment of the recycling process, to show the feasibility of the method. Finally the work is complemented with a real setting up of the proposed design in a recycling company, and with a new application of the obtained glass in a secondary market related to construction sector.Item A systematic approach to define the reuse process of printed circuit board's components(2009-06) Renteriaa, Arantxa; Alvarezb, Esther; Lópezc, Jesús M.; Robótica MédicaReuse is an alternative to extend functional life of products, delaying its introduction into the recycling process. The main objective of this work is to present an automated approach to support the decision about the best way to disassemble electronic components in printed circuit boards (PCBs), in a non-destructive and selective mode. PCBs coming from production rejection may contain valuable and working parts, reusable in different applications with an affordable cost. In addition, removal of potentially hazardous and toxic components is taken into account. An automated dismantling station has been developed as a prototype, to assess the technical and economical feasibility of the process at an industrial scale. Toxic and potentially hazardous components have been extracted and managed according to European directives. First steps include the study of the most suitable PCBs and identification of components. Simulation is applied to decide the best method to extract parts in an automatic way, dealing with the geometry of the components, their location within the PCB, the method used for their soldering to the PCB surface, etc. Next steps deal with the design and construction of the decided solution, composed of an automatic handling device, desoldering and extracting system and functional verification of recovered components.
