Life Cycle Assessment and Design for the Environment are combined in this study to identify and improve the environmental performance of a wooden modular playground. This study covers the whole life cycle of the production process of the playground and its final distribution to the users from a cradle-to-gate perspective. This wooden product was chosen since it is a very representative urban element of the wooden sector in public spaces. To do the assessment, a Galician wood company was analysed in detail. Ten impact categories have been assessed: Abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, human toxicity, freshwater aquatic ecotoxicity, marine aquatic ecotoxicity, terrestrial ecotoxicity and photochemical oxidant formation. According to the environmental results, the assembling stage is the most important contributor to the environmental profile with contributions higher than 60% to all categories. Both lacquering and energy stages are relevant in terms of ecotoxicity impact categories. In addition, the environmental hot spots were identified in the life cycle: the production of wood based materials (with large contribution to ecotoxicity categories) due to the boards, the production of metals (important contributions to acidification, human toxicity and oxidants formation) and the transport related activities (with remarkable contributions to abiotic depletion, eutrophication and global warming) mainly due to the wooden materials. Concerning the results from the eco-design, the proposed strategies were evaluated/selected from a technological, economic and social point of view by an interdisciplinary team of researchers and company workers, showing that the strategies with higher viability were: redesign product to reduction of materials used, substitution of aluminum by stainless steel, combination of maritime and road transport for wooden materials, minimisation of the amount of components in the structure and installation area, definition of a protocol for disassembling and use of the product and packaging and, multifunctional and multiuser design. Important reductions (up to 11%) in the environmental profile (normalised index) can be achieved with these alternatives. The results obtained in this work allow predicting the importance of the selection of raw materials on the environmental burdens associated. Future work will focus on the manufacture of a prototype eco-designed wooden modular playground. © 2011 Elsevier Ltd. All rights reserved. Source

Prototypelab is a project that was born in the University on the bosom of an Educational Innovation Project of the Department of Architectural Design of the ETSAM (Superior Technical School of Architecture of Madrid). It was designed with the aim of exploring the possibilities the parametric architecture provides as a new way of thinking, designing and building architecture, but with a clear vocation of coming close to the industry, technology and the world of innovation. This article presents one of the activities developed in collaboration with CIS Madeira and companies specialized in the sector of timber, on which the research is settled on a prototype which condenses services destined to the public space, energy self-sufficient, a low environmental impact and with the capacity of adapting to different contexts. © 2013 Taylor & Francis Group.

The search for new applications to use boards requires innovation of their properties. The improvement of insulation properties, the possibility to regulate the environmental conditions, the improvement of fire resistance and the increase of physical and mechanical properties allow a more diverse use of boards. Using new components in the production of boards and/or component materials also called composites (1), enables the improvement of these properties. This publication analyses different physical and mechanical properties of various types of single-layer boards produced either based on expanded vermiculite particles bonded with soluble silicate glasses (2) or based on lignocelluloses particles bark of "Pinus pinaster" Ait., agglutinated with cement derivatives of magnesium (3), the latter included in the classification of the norm (4). Commercial wood wool boards (5) are used as reference material. Source
