The COVID-19 pandemic has changed people's habits, causing them to use large amounts of disposable items and exacerbating the already existing issue of pollution. One way to reduce the environmental impact of this shift in daily habits is to recycle these items, e.g. surgical masks that are the most common personal protective equipment against the virus, to produce panels for building applications. In this work, both the thermal and acoustical performance of such panels are evaluated using a small and a large scale investigation under real-world conditions. Small scale thermal tests are performed by means of the Hot Disk instrument while the acoustic investigations are performed by means of the impedance tube. Large scale tests are carried out in a reverberation chamber assessing both the heat flow passing through the wall and the acoustic absorption coefficient of the panels. Finally, the environmental impact of the innovative recycled panel is also investigated in a life cycle perspective. Overall, the material behavior scored well on these tests, suggesting that the proposed approach may be a good recycling method.

COVID-19 大流行改变了人们的习惯，导致他们使用大量一次性用品，加剧了本已存在的污染问题。减少这种日常习惯转变对环境的影响的一种方法是回收这些物品，例如外科口罩，这是最常见的个人抗病毒防护设备，用于生产建筑应用的面板。在这项工作中，此类面板的热性能和声学性能均通过在真实条件下进行的小型和大型调查进行了评估。小规模的热测试通过 Hot Disk 仪器进行，而声学研究则通过阻抗管进行。大规模测试在混响室中进行，评估穿过墙壁的热流和面板的吸声系数。最后，还从生命周期的角度研究了创新回收板的环境影响。总体而言，材料行为在这些测试中得分很高，表明所提出的方法可能是一种很好的回收方法。
