Design principles also have to consider the reprocessing and disposal techniques, which are becoming more and more complex due to legal regulations (Information, for example, with the help of the representatives for environmental protection).
An easy dismantling out of the vehicle and the re-utilization and further utilization of components/component groups, as well as an easy separation into the single parts have to be aspired. If reprocessing is possible and if there is a market for reprocessed products, components/component groups must be removable without being damaged. Accessibility for dismantling tools should be provided; dismantling should be possible with standard tools. The obtention of pure material fractions for reprocessing can be attained by simple dismantling, or by processing techniques, into pure recyclable material fractions. If possible, components/components groups have to be included in recycling circuits already installed.
Regarding connecting techniques the following factors have to be taken into account: Reduction of the number of connection points, utilization of detachable mechanical connections in the form of snap-in or screwed connections, preference of riveted or welded connections instead of glued connections, standardized screw heads (e.g. hexagon, slotted or cross recess types), location of unavoidable signs on a basic part which is as small as possible, utilization of standardized connecting techniques and tools.
Concerning the dismantling techniques, the following has to be observed: All maintenance and mounting criteria can be applied as well; predetermined breaking and separation points should be easily recognizable and accessible for the respective tools. Within the scope of dismantling techniques, the dismantling manual is also documented.
