Development of 100% Recycled Thermoplastic Composites for Sound Insulated Acoustic Panels

Abstract:

Today, environmental problems are increasing rapidly and the focus is shifting to seeking long-term and sustainable solutions. At this point, the economical use of raw material resources is important and this makes recycling a necessity, not a diversity. In this context, environmentally friendly acoustic panels are designed with composites produced by recycling 100% textile and packaging wastes for the noise problem in buildings. Denim fabrics from textile wastes and low-density polyethylene bottle caps from packaging wastes are used. Denim fabrics that are shredded into cotton fibers are blended with ground waste polyethylene granules and porous structures are obtained with the hot press technique. The panels, whose physical and acoustic properties have been tested, are aimed to create an environmentally friendly alternative to existing products.
