“…However, the surfaces of eggshell powder-banana starch and eggshell-orange peel powderbanana starch films were rough due to calcium carbonate (CaCO 3 ) from eggshell powder agglomerating on the starch matrix. The agglomeration leads to poor eggshell powder dispersion, which causes roughness on the film surface [26].…”

The conversion of waste into a valuable product is regarded as a promising alternative to relieving the burden of solid waste management and could be beneficial to the environment and humans. This study is focused on utilizing eggshell and orange peel enriched with banana starch to fabricate biofilm via the casting technique. The developed film is further characterized by field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDX), atomic force microscopy (AFM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The physical properties of films, including thickness, density, color, porosity, moisture content, water solubility, water absorption, and water vapor permeability, were also characterized. The removal efficiency of the metal ions onto film at different contact times, pH, biosorbent dosages, and initial concentration of Cd(II) were analyzed using atomic absorption spectroscopy (AAS). The film’s surface was found to have a porous and rough structure with no cracks, which can enhance the target analytes interactions. EDX and XRD analyses confirmed that eggshell particles were made of calcium carbonate (CaCO3), and the appearance of the main peak at 2θ = 29.65° and 2θ = 29.49° proves the presence of calcite in eggshells. The FTIR indicated that the films contain various functional groups, such as alkane (C-H), hydroxyl (-OH), carbonyl (C=O), carbonate (CO32−), and carboxylic acid (-COOH) that can act as biosorption materials. According to the findings, the developed film exhibits a notable enhancement in its water barrier properties, thereby leading to improved adsorption capacity. The batch experiments showed that the film obtained the maximum removal percentage at pH = 8 and 6 g of biosorbent dose. Notably, the developed film could reach sorption equilibrium within 120 min at the initial concentration of 80 mg/L and remove 99.95% of Cd(II) in the aqueous solutions. This outcome presents potential opportunities for the application of these films in the food industry as both biosorbents and packaging materials. Such utilization can significantly enhance the overall quality of food products.

Eggshell, a readily available natural material, possess remarkable properties that enhance the mechanical and tribological performance of composites, as evidenced by numerous studies. However, a scientometric analysis specifically examining the research landscape of eggshell-based composites has not been previously conducted. This study addresses this gap by employing a data processing, mining, analysis, presentation, and contemporary visualization approach to analyze bibliographic data on the effects of eggshell in composites. This analysis aims to inform researchers and guide future research directions in this promising field. Scopus data was utilized for the scientometric analysis, which encompassed publishing sources, leading authors, frequently used keywords, key publications, and the countries with the most significant contributions. The analysis revealed that “eggshell” is a prominent keyword within the field. Additionally, “Key Engineering Materials” emerged as a publication source with a high number of citations and articles. Notably, India was identified as the leading country in terms of research output. The graphical and quantitative representation of researchers and nations presented in this study facilitates knowledge sharing and fosters collaborative research efforts among academics. Furthermore, this study strengthens the evidence for eggshell potential to improve the mechanical and tribological properties of composites across diverse applications. However, it is crucial to acknowledge that the pre-treatment method and composite composition significantly influence the final material’s strength and durability.
