【 摘 要 】

The specific nature of plastics causes specific problems in waste management. Plastics are relatively inexpensive and versatile with the potential for versatile use in industry, which has led to their rapid development over the past century, which still persists. The aim is to look for the possibility of reusing plastic waste as one of the lightweight filler fillers. It used plastic recycled material recycled from EVA plastic packaging and polystyrene recycled material in various proportions. All are among the medium-recyclable plastics according to their recycling rate. The experimental part of the work is devoted to the verification of the effect of the filler dose on the monitored physical and sound absorption parameters.
