The EU-disposal of End-Of-Life Vehicle Act specifies quotas of material recycling. In addition to pure recycling of materials, the reuse of components and subassemblies makes sense not only in line with the Lifecycle Management and Waste Act (German Law) but also from the economic perspective. The reuse is of high economic and ecologic importance when an acceptance of the used parts and subassemblies can be achieved. For this purpose an unambiguous identification is afforded and an exact classification of the data of the period of use and a high valuable classification have to be achieved and implemented into a visible documentation. Also a reliable classification and identification is necessary to gain the acceptance of the customers as for example described in the VDI 4080, 4081 and 4082 'Recycling of cars. Due to the increasing market for cars and also the increasing amount of vehicle types not only for cars but also of different components per type it is necessary to establish an excellent data network between different recycling companies to improve the contingent and market for reuse parts. Currently an increasing amount is recycled through shredding the entire vehicle and subsequent separation of ferrous from non-ferrous metals. The residual material, upto 30% of the weight of the vehicle is composed of 50% polymers as well as rubber, glass and electronic components. The multimaterial nature of ASR makes it economically impossible to segregate, recycle and reuse. For this reason it is usually disposed of by incineration. The potential for reusability and environmental sustainability behind recycling is still enormous. In addition, even when products follow the recycling route, in most of the cases they are not reused as such, but undergo special industrial processing and re introduced back in the manufacturing process as raw materials. To enhance the sustainability of automotive products new concepts for the utilisation of End of Life Vehicles (ELVs) have to be developed. Combined with State of the Art Information Technology a holistic approach can optimise the ELV treatment, maximise the exploitation and allow for monitoring and process control. To achieve an efficient and economic solution a holistic approach has to consider all stages from manufacturing to dismantling, taking also reuse and recycling into account. The easy and fast identification of the components of vehicles, which are put out of use, is a key prerequisite. If all components can be identified automatically, a Decision Support System can decide if parts have a value worth to invest the effort for retrieving them for reusing, refurbishing or recycling. The system can for example provide information on all operating fluids and localise pyrotechnical devices, which must be deactivated or removed before proceeding. A knowledge based system identifying parts to be dismantled and providing dismantlers with the information required to retrieve these parts can optimise the process. Linked with a Warehouse Management Module, specifically created for dismantling and reuse operations, information about the availability of parts can be used to determine the need and worth of parts to be dismantled. The system can provide information about stock and location of parts and also optimise the storage capacity of a warehouse. This also enables documentation of material streams for ELVs and can provide feedback to the legislation about the overall recycling ratio.
