The recycling of two types of dashboards having a multilayer structure presently available on the market and hence on the scrap cars has been extensively investigated. In both the cases the recycled material showed a strong worsening in the mechanical and impact properties. This effect was attributed to the incompatibility of the different materials constituting the item and to the occurrence of degradation phenomena taking place during processing. To overcome these limitations suitable polymeric additives were added during the recycling. By this procedure materials with improved mechanical properties able to be reused for the same or for similar applications within the car have been obtained.
