| Popis: | Environmental issues are becoming increasingly important, and researchers are developing new technologies and models to reduce environmental impact. The circular economy is a production and consumption model that involves sharing, borrowing, reusing, repairing, reconditioning and recycling existing materials and products for as long as possible. This study focuses on the concept of reuse and, specifically, how to reduce waste generated by pandemics through recycling and reusing facemasks made of polyamide fabric. Facemasks can be reused to refurbish buildings in low-income contexts. To assess the reutilization potential of recycled bulk polyamide fiber, thermal, acoustic, and fire performance properties were assessed experimentally. The results show that they are comparable to commercial insulation materials such as glass wool and mineral wool in terms of thermal conductivity, while also demonstrating good sound absorption performance at medium and high frequencies (greater thickness and density will increase the amount of insulation and sound absorption). The material’s fire performance is similar to that of other synthetic insulation materials, such as EPS. However, the performance is worse than for common organic insulation materials, such as cellulose. Finally, a lowcost, self-portable insulation panel concept designed for indoor installation was tested for material performance. Considering these properties, this solution may represent a significant opportunity to enhance thermal and acoustic comfort in vulnerable energy-poor households, bringing clear environmental benefits and positive social implications. This research was partially funded with grants from the Centre for Development Cooperation – Universitat Politècnica de Catalunya for the local cooperation project “REEhabilitant el Raval” (grants 2020-D005, 2021-K003 and 2022-C007), by the Catalan agency AGAUR through its research group support program (2021 SGR 00341), and by the Department of Mechanical and Industrial Engineering of the University of Brescia through the MetATer PRD project. The authors would like to thank Prof. Edoardo Piana for access to the applied technical physics laboratory at the University of Brescia, and to Dr. Laia Haurie for access to the materials laboratory at Universitat Politècnica de Catalunya, and for their valuable advice.
