Automotive headliner scrap is comprised of post-industrial recyclates (production rejects, trim offal) (PIR) and post-consumer recyclates (PCR), i.e. headliners discarded from vehicles that have reached the end of their useful lives (End of Life Vehicles or ELVs). This waste stream exceeds 100 million pounds yearly in the United States and is currently 100% disposed in landfills. This paper describes an innovative process that converts headliner scrap into finished composite panels using VOC-free adhesives. The resulting product has unique physical properties and can be used as vertical decorative panels in the transportation industry, such as automobiles, recreational vehicles, refrigerated trucks and tractor trailers. The boards' physical properties will be compared to targeted competitive products, i.e. Luan plywood or polypropylene/glass fiber composites. Luan, also known as Meranti or Philippine mahogany, is a wood material glued with urea-formaldehyde (UF) resins, that is imported from South East Asia. It is extensively used by the North American recreational vehicle industry for interior wall panels. Unlike the new composites described in this publication, Luan emits formaldehyde which is rated as a carcinogen by the U.S. EPA. Customers using Luan are now under pressure to drastically reduce VOC emissions, especially formaldehyde, under current CARB II regulations from the California Air Resources Board.
