Original Abstract

Referring to the circular economy model, end-of-life household materials (EoLHM), such as packaging and clothes, could be converted into building elements with thermal and acoustic properties; for example, they could be converted into panels to be installed indoors for building refurbishment. Given the high availability almost anywhere, panels made of EoLHM would represent an alternative to commercial insulating materials that, even though relatively cheap, cannot be afforded by disadvantaged people. This paper presents a multidisciplinary analysis aimed at the characterization of polyamide 6.6, obtained as a waste from the production of non-surgical face masks. The research focuses on the thermal and acoustic properties of the material. The properties have been determined experimentally through the guarded hot plate method hot and the impedance tube technique. Then, the influence of the panel's position on the indoor operative temperature and the reverberation time has been analyzed through numerical simulations. Results show that, from the thermal and acoustic point of view, this waste is suitable for the realization of building panels, and the performance depends on the density and the thickness of the material. However, aspects such as fire resistance and the containment of the material need further investigation.
