A recent scientific review examines the potential of recycled PET bottles for the development of acoustic metamaterials.
Through specifically designed resonant structures, such materials could contribute to reducing low-frequency noise in buildings – an area where conventional solutions often require considerable space.
The combination of circular economy and acoustics is particularly interesting: plastic waste could become a raw material for lightweight, compact, and tunable sound absorbers.
The review considers not only the acoustic potential but also how these approaches could eventually be translated into practical solutions for the built environment.
The study shows how recycled materials could open new pathways for compact, sustainable, and high-performance acoustic solutions.
