Does the Spinning Scale affect the degradability of home-compostable polymers?

The presentation will show the correlation between three different melt-spinning-scales and the degradability. For each Production-Scale, a prototype will be constructed and shown

This work compares spun Polybutylene Succinate (PBS) on Lab-, Pilot- and Industrial-Scale. Those fibers were characterized in their physical properties and degradability behavior to show the impact of the spinning scale on the degradability of the fibers. This work seamlessly connects to the lecture given in 2022, where different Biopolymers were compared to their petrochemical alternative. The lecture from 2022 showed the significant impact of meltbinding fibers in teabags on the environment. Replacing Polypropylene (PP) with PBS improves this situation tremendously. The goal is to construct a product (the teabag) from the spun fibers that will be the focus of degradability studies and Life-Cycle-Assessments for each spinning scale. These prototypes will be shown at the conference.
