Exploring the Use of Unprocessed Waste Chicken Eggshells for UV-Protective Applications

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.

Pathways for Sustainable Utilization of Waste Chicken Eggshell

“…Fecheyr-Lippens et al [89] explored WCES for the protection of two regularly used synthetic polymers (polystyrene and nylon) from ultraviolet (UV) degradation and reported that unprocessed WCES contains UV-protective additives for the protection of photodegradable materials. The outcome of the investigation further revealed WCES as a novel, cost-effective, durable, and ecologically benign protector of synthetic polymers from UV light and performed better than titanium dioxide (TiO 2 ) and other inorganic additives.…”

Synthesis of hydroxyapatite from eggshells via wet chemical precipitation: a review

“…60 Most eggshell waste is discarded without further processing by sending it to landll at a cost of more than $40 a ton depending on the location of the landll. 44,[61][62][63] In recent years, the syntheses of HA from natural sources has been extensively studied by researchers. 64 The abundance of eggshells, the necessity of recycling them to avoid pollution, and the consideration of their elements-and oxides-rich nature have prompted the researchers to study eggshells and investigate the possibility of employing eggshells in important areas as a natural resource.…”

Recycling of Chicken Egg Shells into Nanopowder: Synthesis, and its Properties

“…Furthermost eggshell remaining is thrown away since additional treating is too costly and burdensome 4 . Numerous researchers have been observed for methods to use the eggshells discarded, such as, via eggshells powder as a steadying material for cultivating soil properties, Ultraviolet-protecting essences 5,6 and as a basis of Calcium in human diet 7 .…”
