Comparative Life Cycle Assessment (LCA) between standard gypsum ceiling tile and polyurethane gypsum ceiling tile Rodrigo Bravo, Alba Alameda Cuenca-Romero, Lourdes Calderón Carpintero, Verónica Rodríguez Sáiz, Ángel Gutiérrez González, Sara Gypsum ceiling tile Polyurethane waste Life Cycle Assessment-LCA Cradle to grave Environmental assessment Environmental impact Circular Economy In this paper, the LCA of two gypsum ceiling tiles is compared, the first one is a traditional gypsum tile and the second is a new eco ceiling tile in which polyurethane foam waste has been incorporated. Both tiles were made at one of the largest gypsum tile factories in Europe. The life cycle assessment has been considered from cradle to grave for which the corresponding production stages have been defined. This includes the extraction and transportation of raw materials, the manufacturing process, transportation to the client, the use of the product and the end of its useful life. The results show that the tile with polyurethane has a better environmental performance than the standard commercial ceiling tile. This is quantified as a 14% reduction in energy consumption, a 14% reduction in CO2 emissions and a 25% reduction in water consumption compared with the standard tile, all the while maintaining the technical performance. An analysis of the results suggests that the new eco product has a competitive advantage on the market thanks to its environmental improvements and good technical performance. 2023-03-06T07:49:52Z 2023-03-06T07:49:52Z 2022-03 info:eu-repo/semantics/article 0378-7788 http://hdl.handle.net/10259/7492 10.1016/j.enbuild.2022.111867 eng Energy and Buildings. 2022, V. 259, 111867 https://doi.org/10.1016/j.enbuild.2022.111867 info:eu-repo/grantAgreement/EC//LIFE16 ENV%2FES%2F000254/EU/REcovery of POLYurethane for reUSE in eco-efficient materials/LIFE-Repolyuse/ info:eu-repo/grantAgreement/Junta de Castilla y León//BU070P20//Prefabricados de mortero eco-eficientes aligerados con residuos poliméricos industriales con propiedades estructurales y térmicas mejoradas/ http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
