  • LCA study of different recycled sound absorbers from melamine foam waste [Elektronski vir]
    Kavka, Urban ...
    The main focus of this study was to investigate the use of melamine foam waste in the production of sound absorption panels, with emphasis on performing a life cycle assessment analysis (LCA) for two ... different types of sound absorbers. LCA Impacts were studied for panels made from rigid monolithic melamine foam and from randomly cut fragments. Most impor- tantly, the different shape requirements can greatly affect the recycling potential of the material as well as the acoustic and environmental performance. Environmental impacts were cal- culated for different units. It has been shown that per surface area of sound absorbing panel, which is 0.675 m2, the difference between the two types can be misleading. Therefore, evaluating the environmental impact per sound absorption area in each oc- tave band provides greater potential for a holistic comparison of performance. Along with the acoustic performance studies, the overall performance and impact of each type was determined, with the monolithic type having better overall performance up to 250 Hz and the fragment absorber above. The study provides important insight into the evaluation process by offering a novel comparison of overall performance, PAE
