The first image illustrates the traditional linear life cycle of a car headlight: raw materials are extracted, transformed into a product, used by consumers, and eventually discarded. This “take–make–dispose” approach leads to high resource consumption and generates significant waste — a model that is no longer sustainable for modern industry.
The second image presents the circular life cycle, where materials are recovered and reused at the end of the product’s life. Instead of disposal, the headlight is recycled, and its components are reintegrated into new production processes. This shift greatly reduces environmental impact while supporting innovation and long-term resource efficiency.
A key enabler of this transformation is digital twin technology — virtual models that simulate a product’s performance and life cycle in real time. By using digital twins, engineers can design more sustainable, repairable, and efficient products, paving the way for truly circular manufacturing systems.
Within the CIRC-UITS project, these concepts come together to demonstrate how digitalization and circularity can reshape European industry, making it smarter, greener, and more resilient.
