  text: Political goals, emerging EU sustainability regulations, and industrial digitalization
    are driving the introduction of Digital Product Passports (DPPs) to enhance transparency,
    traceability, and compliance across product life cycles. However, the appropriate
    granularity of DPP integration across product architectures remains ambiguous.
    This paper introduces a structured, decision-oriented framework that links product
    structure, regulatory relevance, and information depth to define consistent DPP
    levels, supporting both industry implementation and future standardization.

  text: The circular economy offers decisive advantages over the currently prevalent
    linear economy in industry. Firstly, the reuse of products, individual parts and
    material reduces the need for new production or generation and the associated
    consumption of energy and resources. Secondly, it helps to avoid the generation
    of waste. Early consideration of circular economic principles in product development
    processes is essential to specifically promote reuse, reparability and recycling.
    Efficient recycling of assemblies requires well-defined strategies. However, various
    challenges hinder the efficiency of technical recycling processes in industrial
    applications. This paper presents an Ishikawa (fishbone) diagram-based approach
    to systematically identify and categorize these influences. The method is implemented
    within an industrial framework, highlighting key obstacles such as material composition,
    design constraints, use of technology, framework conditions, economic limitations
    and regulatory challenges. By applying a scenario analysis, this approach examines
    potential future developments and their impact on recycling-oriented design choices.
    This helps to identify critical influencing factors and supports the development
    of resilient and sustainable industrial practices. This framework will serve as
    the foundation for developing an automated approach to circular design, enabling
    industries to more effectively integrate sustainability into their processes and
    adapt to changing environmental demands.

  text: "Für die Aufrechterhaltung der natürlichen Ressourcen ist eine effiziente
    Nutzung dieser essenziell. Vor diesem Hintergrund untersucht das vorliegende Paper
    die Rolle der Kreislaufwirtschaft als wegweisendes Wirtschaftsmodell, das von
    der Europäischen Union gefördert wird. Ziel der Kreislaufwirtschaft ist es, den
    Ressourcenverbrauch und die Abfallproduktion zu minimieren, indem ein kontinuierlicher
    Kreislauf aus Nutzung, Wiederverwendung und Recycling von Materialien geschaffen
    wird. \r\nEin zentraler Aspekt dabei ist der Produktentwicklungsprozess (PEP)
    - ein vielschichtiger Prozess mit zahlreichen Einflussfaktoren und theoretisch
    unbegrenzten Gestaltungsmöglichkeiten. Diese Vielfalt führt jedoch zu erheblichen
    Entscheidungsunsicherheiten, die die Umsetzung von Kreislaufwirtschaftsprinzipien
    erschweren können. Um diese Herausforderungen zu adressieren, wird ein methodischer
    Prozess vorgestellt, der eine systematische Klassifizierung im Zusammenhang mit
    umliegenden Bauteilen ermöglicht. Die Methodik basiert auf einer strukturierten
    Bewertung von Bauteilen hinsichtlich ihrer Relevanz für die Kreislaufwirtschaft.
    Dabei werden zentrale Aspekte wie Wiederverwendbarkeit, Recyclingfähigkeit und
    Ressourceneffizienz berücksichtigt, darunter: \r\n•\tHandelt es sich um ein Gebrauchs-
    oder Verbrauchsprodukt?\r\n•\tIst das Bauteil eine Wiederverwendung oder eine
    Neufertigung?\r\n•\tIst das Bauteil standardisiert, zugekauft oder individuell
    ausgerichtet?\r\n•\tWelche primäre Funktion nimmt das Bauteil ein?\r\nDiese strukturierte
    Klassifizierung unterstützt die Entscheidungsfindung bereits früh im PEP. Sie
    ermöglicht es Produktentwickelnden, Potenziale für die Kreislaufwirtschaft frühzeitig
    zu erkennen und gezielt nachhaltige Maßnahmen zu ergreifen.\r\nDie entwickelte
    Methodik bildet somit eine Grundlage für die Integration kreislaufwirtschaftlicher
    Prinzipien in den Entwicklungsprozess. Insbesondere im Kontext moderner Anforderungen
    des Mobility Management zeigt sich ihr Potenzial, nachhaltige Innovationen gezielt
    zu fördern und die Umsetzung der Kreislaufwirtschaft in der industriellen Praxis
    zu erleichtern."
