Companies receive numerous customer inquiries and regulatory requirements while attempting to offer new services to enhance sustainability, leading in total to an increase in the number of product-related requirements. Digital Twins serve as enablers for meeting these requirements, whereas new challenges arise for companies through the introduction of Digital Twins. Digital Twins represent an order-specific configuration and must be structured differently according to requirements and thus as modularly as possible. This paper aims to provide a systemic approach with a concept for a Modular Digital Twin for generating and exploiting Product Sustainability Information to leverage sustainability potentials towards Service-oriented Business Models. The approach is concretised by means of a selected use case regarding energy-efficient production control of an automated model factory. We can show with this use case that the systemic approach with the concept of a Modular Digital Twin is applicable for energy consumption of machinery motors' simulation and for the calculation of an optimised motor speed.
