Definición de uso y análisis de ciclo de vida para la mezcla de poliestireno expandido (EPS) y polipropileno (PP) reciclados, aplicada en el sector de la construcción, como alternativa de aprovechamiento de residuos sólidos

Abstract

This project developed an alternative for the utilization of solid plastic waste, determining the use of polymeric synthetization, made from recycled polypropylene and expanded polystirene, leading the research to the construction sector because of the extensive research and experimental background that the reincorporation of plastic as a waste has had in the construction sector, From the comparison of the physical-mechanical properties of the mixture with different potentially replaceable materials, polyvinyl chloride (PVC) being the material selected by the similar values of its properties with respect to those of the mixture (EPS +PP), specifically used for the coating of electrical installations and internal communications of a site. Subsequently, it was demonstrated through SIMAPRO software that the material (EPS+PP) generates less environmental impact than conventional (PVC), performing a technical-environmental assessment based on the comparison of a life cycle analysis already performed on PVC, with the elaboration of the mixture, Both from cradle to door, developing the proposed industrial process along with the material, energy and atmospheric balances necessary for the LCA. Released, new possibilities for incorporating circular economy models in the construction sector.
