Los impactos ambientales de los pavimentos se minimizarían seleccionando revestimientos de piedra natural y baldosas cerámicas, según un estudio que analiza diferentes sistemas de pavimentos interiores teniendo en cuenta todo su ciclo de vida.
Published in the journal Science of The Total Environment, this study assess the whole life cycle of the different flooring systems, including the product stage, transport to the construction site, installation of all construction elements, use, as a function of pedestrian traffic intensity, and valorisation by recycling; as a transition scenario towards a circular economy. “The importance of considering the whole life cycle versus just the production stage was evidenced when comparing alternative construction solutions,” as the authors stand out.
As a novelty, the environmental impact data of the coverings’ production chain has been taken from previously certified Environmental Product Declarations (EPDs), as these are standardised public documents devised to provide environmental life cycle information. “The method adopted in the study suggests that, though the use of EPDs as information source is interesting, erroneous conclusions may be drawn if the EPDs are not comparable and/or if the comparison is not made in the building context,” points out Pere Fullana i Palmer, director at the Chair and co-author of the study.
“Within the frame of the study, the results show that the flooring systems with inorganic coverings perform best in the global warming, acidification, eutrophication, photochemical ozone creation, and abiotic depletion for fossil resources impact categories, whereas laminates perform best in the abiotic depletion for non-fossil resources and ozone layer depletion impact categories. Lastly, the carpet flooring system performs worst in every impact category except photochemical ozone creation potential,” as stated by Eliseo Montfort, Professor at the Universitat Jaume I and co-author of the study.
In light of these results, the researchers stress that “an appropriate selection of construction materials plays a major role in a building’s sustainable profile.” Therefore, “we all should consider selecting flooring materials that will help maximize the quality of an indoor environment while minimizing damage to the natural environment,” concludes the director at the Chair.
