Abstract

Photodegradation causes a steady loss of the useful physical, mechanical and optical properties of materials, necessitating their replacement over time. Because UV (Ultraviolet) light is most harmful in this regard, many materials now contain UV-protective additives. However, these additives are not always effective and durable, can be expensive, and their natural extraction or synthetic production can be harmful to the environment. Here, we investigated the use of unprocessed chicken eggshells in providing UV protection to two commonly used synthetic polymers: polystyrene and nylon. We show that unprocessed chicken eggshells provide a durable and effective UV protection. Our data sets the stage for future research to find a practical way to use the large amounts of unprocessed chicken eggshell waste as novel, economically appealing and environmentally friendly UV-protective additives.
