As a part of the Net-Zero initiative there is a clear need for manufacturing of acoustic materials from sustainable sources and methods, more efficient use of materials and machines for improved life including meta-materials, safety and functionality and for the adoption of modern methods of construction (MMC) which include sustainable acoustics solutions, e.g. better and more sustainable room acoustics quality and insulation. As a part of the Net-Zero initiative there is a clear need for manufacturing of acoustic materials from sustainable sources and methods, more efficient use of materials and machines for improved life, safety and functionality, materials passport platform or circularity material passports that allow to an engagement with the Life Cycle Assessment (LCA) of a sustainable acoustics solution, more sustainable room acoustics quality, insulation and ventilation.
