Mercedes-Benz E-Class Manual page 42

During the development of the E-Class, these components
were specifically prepared with a view to their subsequent
recycling. Along with the segregated separation of materials,
attention was also paid to ease of dismantling of relevant
thermoplastic components such as bumpers, wheel arch
linings, outer sills, underfloor panelling and engine
compartment coverings. In addition, all plastic parts are
marked in accordance with international nomenclature.
In the subsequent shredding of the residual body, the metals
are first separated for reuse in the raw material production
processes.

The largely organic remaining portion is separated into
different fractions for environment-friendly reuse in raw
material or energy recovery processes.
With the process chain described below, an overall material
recyclability rate of 85 percent and a recoverability rate
of 95 percent were verified on the basis of the ISO 22628
calculation model for the E-Class as part of the vehicle type
approval process (see Figure 4-1).
