Research joint project »ERMA - Energie- und ressourceneffiziente mobile Arbeitsmaschinen« at the RPTU Kaiserslautern-Landau is successfully closed! Why optimizing constantly the wrong thing instead of doing directly the right thing? How products of tomorrow become resources of over morrow describes Michael Braungart fascinating and clear in his work »cradle to cradle«. Braungarts easy credo at this is to put intelligence finally at the beginning in product engineering. The point is also to form whole lifespan of a product. According to this waste management belongs to develop and design assignment. The fact that material will be recycled doesn’t makes it automatically ecofriendly at the center of commercial vehicle technology especially not if recycling is not explicitly scheduled at fabrication. An important condition is the knowledge of all ingredients of the products, underlying technical processes and intelligent ahead planning of sustainable product systems over their whole life’s journey. These challenges were motivations for the joint project ERMA of the research group product engineering at the center of commercial vehicle technology (ZNT) at RPTU. [...]
