"A masterpiece of joining technology will cause a real headache in terms of recycling"

Lightweight design is changing the mix of materials used in the car. Established metallic materials are being joined by composites such as CFRPs and sandwich materials. This is a challenge for the recycling industry, as Ansgar Fendel, Managing Director of Remondis, explains in the interview. It will become increasingly difficult to achieve the required recycling quotas for end-of-life vehicles in coming years.
lightweight.design: Lighter vehicles consume less fuel and give off fewer emissions. At the same time, increasing use is being made of fiber composite materials or plastic-metal hybrids. Do you think that lightweight design is an environmentally friendly technology?
Fendel: That's an interesting question to which there is no easy answer. The argument is plausible from the perspective of reducing emissions and fuel consumption, but from a recycling perspective, the situation is clearly different. It is apparent that the increased use of lightweight design increases the complexity...
