  text: Aspects such as sustainability and resource conservation are playing an increasingly
    important role, not only for ecological reasons but also for economic ones. This
    is also reflected in product design. Anyone developing products today should directly
    consider the life cycle, opportunities to extend the usage phase, and the end
    of the product’s life. In the medium term, this is likely to lead to competitive
    advantages. Interlocking strategies offer a holistic solution.
