Biodegradability of "Polyurethane Shoe Sole": Ensuing by the Soil Burial Degradation

Popis výsledku v původním jazyce

Polyurethane soles are slowly replacing the natural materials: leather and natural rubber as shoe sole materials and gradually in the process, reforming the shoe industry. Polyurethane (PU) prepared from a new kind of organic polymer material. The global PU sole market which was USD 5.26 billion in 2022, is expected to reach USD 8.19 billion by 2030. Beside this, increasing social awareness of environmental sustainability that exhiiarated a shift toward the use of eco-friendly materia]s like PU in footwear industry. It is also the responsibility of the footwear researchers to promote socially responsible production to develop sustainable footwear. Biodegradation of the PU waste is still chal!enging due to its complex molecular composition. Here, Polyurethane sole were produced from polyester polyol, nonehtylene glycol, and commercial isocyanate. In the soil burial degradation method, PU shoe sole degradation was not significant; approximately 15% weight loss occurred after 60 days of incubation. Furthermore, microbial growth in soil and mechanical, thermal, and morphological tnvestigations indicate a slight deviation of the PU shoe&apos;s sole internal structure from the original one.
