Aprovechamiento del residuo industrial etil vinil acetato eva para su uso eficiente como material insonorizante de ruido ambiental y ocupacional

Abstract

At present, noise pollution and the impacts generated by the accumulation of industrial wastes are two pressing environmental problems that contribute to the progressive deterioration of ecosystems. To generate new strategies that contribute to mitigating both problems, the present study proposes the reuse of the Etil Vinil Acetate (EVA) industrial waste from the automotive industry to attenuate environmental and occupational noise, taking advantage of its isonorizing potential. For this purpose, plates were constructed using different types of EVA, provided by the packaging material recycling company of vehicle assembly industries to perform soundproofing tests and determine which type of EVA has the greatest potential to minimize both types of noise. The industrial waste EVA III, having a higher density, turned out to be more efficient to increase occupational noise with serious industrial sound, while the EVA I reflected greater efficiency to increase occupational and environmental noise with high sound, being also the lowest density. This research contributes a contribution to the use of industrial waste, present that predominates in landfills, occupying a high volume. It will provide the industry with an efficient and cost-effective method for the reduction of both external and occupational environmental noise.
