Sound Absorbing and Insulating Low-Cost Panels from End-of-Life Household Materials for the Development of Vulnerable Contexts in Circular Economy Perspective

From a construction point of view, neighborhoods with residents living at or below the poverty threshold are characterized by low energy efficiency buildings, in which people live acoustic discomfort no viable options for home improvements, as they usually can not afford materials and labor costs associated. An alternative to this is use low-cost insulating elements made non-conventional acceptable properties. Given that household their end-of-life (EoLHM) free available also more disadvantaged population, be used build panels such contexts. This approach embraces several benefits since it reduces amount waste produced, footprint deriving from extraction new raw and, highlighting potential EoLHM, discourages abandonment waste. In paper, properties cardboard, egg-cartons, clothes, metal combinations them, investigated means impedance tube technique. The measured sound absorption coefficient transmission loss have shown EoLHM realization panels. However, none analyzed shows absorbing same time, must wisely selected. innovative supports circular economy improvement condition low-income households.
