ABSTRACT- Modern society is characterised by the extensive use of complex multi-component consumer products, of which passenger vehicles are a typical example. In Europe targets have been laid down by EU legislation for the recycling rate of passenger vehicles to be achieved within the nearby future. Moreover, calculations to predict the recyclability of the car are required for the type-approval of cars, which have to obey to the targets as laid down in the EU recycling legislation. This paper discusses how the link between design software tools and recycling models can be established in order to predict the recyclability of the car during the design phase, as well as to be able to apply design for recycling on a solid technological basis. Due to the complexity of the design of the car, and the time-varying parameters such as the life-time, weight and composition, optimisation of recycling can only be realised based on a sound technological basis, in which the dynamic and statistically distributed parameters affecting the recycling rate are described and understood. This paper gives a brief overview of the dynamic and recycling models, which are developed for optimisation of the recycling of the car and the calculation of recycling rates. These models describe the relationship between design, liberation, process characteristics of physical and metallurgical processing, and the material quality of recycling (intermediate) products. The performance of a large scale industrial recycling experiment based on the theory presented here is also discussed. The produced data are calculated on the basis of sound sampling statistics and data reconciliation; and are used to calibrate the fundamental models. The developed models are essential in order to calculate and predict the recycling rate of passenger vehicles in the design phase. This paper links the recycling of passenger vehicles from a material and energy perspective with recycling technology and design, taking cognisance of economy, environmental impact and legislation. Therefore, this paper discusses the basis of a fundamental framework that links CAD design software and recycling models and hence gives a good indication of the recyclability of products. It is also indicated that without any statistics involved in the estimation of recycling rate calculation, as well as the inclusion of the issues and theory discussed in this paper, the ISO norm for recycling rate calculation is really useless.
