Abstract: Ethylene vinyl acetate (EVA) is a polymer used in the manufacture of school supplies, sports and footwear. The production process generates substantial amounts of residues, which should be reused. The aim of this study was to examine if plates produced from a mixture of EVA and cement can be used for acoustic insulation, thus giving a proper destination to the residues. For that purpose, the best mixture of EVA and cement was examined. The characteristics of the manufactured plates were analyzed, and water absorption, acoustic, flammability, and microscopic tests were carried out. The results showed that the acoustic reduction of the plates was more efficient in the frequencies between 800 and 1000Hz as compared to concrete walls. This finding allows to conclude that EVA plates can be used for acoustic insulation, thus giving a proper destination to the residues.
