Design for Acoustic Excellence in Conjunction With Environmental Roadmap

Acoustic packages are designed to excel in their primary function: sound reduction. Thereby, they already improve one environmental aspect, which is the reduction of the external noise emission. This paper explores the possibilities of increasing environmental value intrinsic to the product as well as the related potentials such as waste saving and the use of recycled materials. The discussion will also address the disposition of the acoustical parts when the vehicle is at the end of its useful life (ELV.) The critical issues within the recycling loops of acoustic packages as well as the potential of the recovered streams are highlighted.
