Most studies on the properties and recycling of automotive shredder residue (ASR) have been carried out without fully understanding the composition of the input scrap. Equally important is understanding the type of shredding process, and types of processes utilized for separation of ferrous and non-ferrous metals from the shredded material. The Vehicle Recycling Partnership (VRP) has been conducting a project:“Study of Plastic Material Recovery From Automotive Shredder Residue” [1]. One of the objectives of this VRP project is to determine the relationship between the shredder input and ASR properties. A 1995 Dodge Stratus was dismantled in detail to obtain information necessary for the project, such as material usage in the vehicle [2]. Then, under tightly controlled conditions, 14 late model Chrysler Cirrus and Dodge Stratus automobiles were shredded and processed.

A descriptive analysis of the Vehicle End-of-Life (VEOL) process in the U.S. is presented. The material recovery process and the reuse of parts are discussed. A computer VEOL model will be presented which would ultimately be used to analyze the impact of specific regulations, markets factors, and/or business policies, on the recyclability of materials and the reuse of parts. The computer model includes several stages of the VEOL process, including vehicle sales, usage, and retirement; also the dismantling of the retired vehicle, shredding operations, parts and vehicle rebuilders, maintenance and repair. An example of the use of the VEOL computer model on material substitution is presented.

With the increasing demand to improve recyclability of automobiles worldwide the Vehicle Recycling Partnership (VRP) a cooperative effort among Chrysler, Ford and General Motors has been formed. The VRP has been developing preferred practices for improvement of recyclability for future vehicle subsystems. These preferred practices are intended to assist engineers and designers in improving recyclability without impairing the performance of the subsystem. This paper discusses the practices of specific design for recycling of plastic bumper fascia systems and what the designer should consider in developing a design to improve and maximize recyclability.
