When product development is considered in the fiber area, the desired properties of the product are in the foreground. This is correct and important, as this is the only way to satisfy users' needs ideally. There is much talk about the recyclability of materials, but the fact that less than 10% are recycled globally every year suggests that an enormous amount is either burned, buried, or disposed of improperly. In particular, improperly disposed products pose a significant threat to nature due to accumulation and conversion to microplastics later on. This presentation will use several disposable products to show how product development should be adapted to minimize this environmental impact. Various studies, part of a doctoral thesis, explored the performance spectrum of various home-compostable biopolymers and examined the influence of different process parameters on subsequent degradation. Multiple parameters, such as residence time and fiber cross-section, can be used to adjust the degradability of the fibers. Modifying the production process combined with an application-specific degradation profile for the fiber used complements product development by considering how likely a product will end up in nature.
