摘要

The topic of sustainability is currently not only omnipresent in research and politics but is also gaining significant importance in the industry. Different customer groups are increasingly attaching importance to sustainable products and adapting their purchasing behaviour accordingly. One important field of action for achieving ecological sustainability is the circular economy. Circular economy describes a cycle-based model of production and consumption, whereby materials and products are to be recycled after use in such a way that further use of the product, or the materials used is possible. This can be done in different degrees of recovery, for example by reuse, repair, recycling, remanufacturing etc. Remanufacturing offers an industrially attractive recovery option with high value retention. However, it also places the highest demands on the product to be recycled as the quality is described “as new”. The Landshut Level Model of Remanufacturing (LEMOR) is a comprehensive model for the step-by-step assessment of the suitability of a component for remanufacturing from a technical, economic and strategic perspective. This ranges from a review of the basic technical suitability to the influence of the individual damage pattern on the remanufacturing process. The assessment can be divided into a generic and a component-specific spectrum. The generic evaluation is specified in more detail by defined component properties which were collected in the component-suitability-assessment. This initial part of the evaluation shows the possibility of integrating different production processes (in particular additive manufacturing processes in combination with subtractive processes) to expand and realize high-quality and complex remanufacturing processes. A software tool was developed for the automated and user-friendly collection of component properties and their automated comparison with the requirements catalogue for testing remanufacturing suitability.
