For this purpose, the competences of Fraunhofer IGCV in resource-saving manufacturing, recycling of composites, and biological transformation are bundled and consistently captured by knowledge modeling using graph-based design languages. This approach enables running different optimization scenarios along the value chain starting from the product development phase and comparing different variants based on various aspects such as ecological compatibility or costs, for example.
In the NewAirgiLity project, an important step is taken to bring together the digital circular economy with the recycling economy for fiber-reinforced plastics. Above all, the interdisciplinary collaboration between technical expertise (recycling and circular economy) and digitization (data management, knowledge preservation, programming) promotes the rapid development of models and functions to advance the digital circular economy. The model developed in the project networks the existing state of the art in recycling for the first time and bundles the knowledge in a digital process chain. This networking enables to quickly and objectively answer complex questions regarding suitable recycling routes as well as material flows. Furthermore, it enables to access knowledge flexibly (Figure 2).
Additionally, the knowledge of several manufacturing technologies (AFP, pultrusion) is bundled in the model and can be used for an initial assessment regarding potential supply, labor, and material costs. In addition, by combining this with an ecological evaluation (GWP), the project can make a statement regarding the environmental impact.
By integrating simulation and design guidelines, the functional integration of other software tools directly complements the process of offering with design optimization and load case-control. Combined with the deposited know-how of recycling aspects, the breakdown of process and manufacturing costs can be extended by the ecological sustainability of the manufacturing technologies and the product.
