BMW Recycling.
Your BMW is the product of a comprehensive recycling concept. But what exactly does that mean in practice? It means that all the requirements
of recycling are taken into account from the start, in the initial development of a BMW. One example is the choice of materials carefully selected
to preserve resources and ensure efficient recycling compatible with the environment. Each BMW is designed and built for simple and
economic recycling after its – long – running life. We have been collecting the know-how required for this purpose ever since 1994 at the unique
BMW Recycling and Dismantling Centre (RDC) near Munich. Please contact your BMW partner on all matters regarding your end-of-life vehicle.
He will be happy to advise you.
All dimensions in the technical drawings are given in millimetres. Luggage capacity up to 340 litres (VDA measurement).
