“…Additionally, chemical applications of eggshells in supercapacitors [7], rechargeable batteries [8], adsorbent materials for gold ions in electroplating waste [9], dyes [10], and the elimination of heavy atoms from dilute waste solutions [11] have been reported. Recently, modifying the stability of dye-sensitized solar cells using ruthenium dyes embedded in eggshell membranes [12] and generating power using a direct methanol fuel cell with the protein components of eggshell membranes as proton conductors [13,14] were reported. However, for continued advancement in the field of eggshell recycling, developing materials wherein eggshells and eggshell membranes exhibit effective functions that have not yet been reported is necessary.…”

Eggshells can adsorb chemicals, but no studies regarding the adsorption of gaseous chemicals using eggshells or eggshell membranes have been reported. The purpose of this study was to apply chemical adsorption using eggshells to the maintenance of human health. Building materials containing eggshells may reduce the concentrations of toxic substances, such as formaldehyde, via the adsorption functions of eggshells. In the bending study, the strength of board-shaped gypsum-containing eggshells was not compromised when the content of eggshells within the gypsum was ≤10%. Compared to those of gypsum boards containing seashells, which comprise calcium carbonate, similar to eggshells, gypsum containing eggshells displayed a higher strength. In the adsorption study, board-shaped gypsum containing eggshells placed inside a sealed box rapidly decreased the formaldehyde concentration. A gypsum board with an eggshell content of ≥5% could limit the formaldehyde concentration to ≤0.08 ppm. Furthermore, the results were compared with those of adsorption studies using plasterboard mixed with other natural materials. Eggshells displayed excellent functionalities as novel formaldehyde adsorbents.

“…Accordingly, the ESM surface contains numerous functional chemical groups (amine, amides, carboxylic) that play a major role in its functionalization or replication. Thus, in different forms (pristine, modified, or carbonized), the ESM has been used as (i) component in triboelectric nanogenerators [34], fuel cells [35], supercapacitors [36], lithium-ion battery [37]; (ii) sorbent of water contaminants, such as dye molecules [38] or heavy metals [39]); and (iii) immobilization platform for biosensors [40]. Biomaterial with an antibacterial and anti-inflammatory activity, the ESM porous structure can favor the diffusion of gas and water molecules assisting the attachment and proliferation of the cells.…”

ZnO-based nanostructures emerge as promising materials due to their potential applications in fields including electronic devices, photodetectors, photocatalysts, biocides, etc. The bio-template-mediated synthesis is a straightforward approach for obtaining inorganic or hybrid organic/inorganic materials with tailored morphologies and functional properties. Eco-friendly waste, eggshell membrane (ESM) is an ideal bio-template for the development of 3D hierarchical porous architectures due to its specific 3D interlaced fiber protein network structure. Therefore, this chapter is focused on the ESM-mediated synthesis of 3D fibrous architectures based on ZnO, the ESM organic network being functionalized with inorganic nanostructures or replicated into an inorganic one as follows: i) coated with ZnO layer by RF magnetron sputtering, (ii) covered with ZnO by electroless deposition and (iii) replicated into ZnO web by biomorphic mineralization. The obtained ZnO shows wurtzite structure, band-gap value and emission bands typical for this semiconductor. The electrical properties of the ZnO fiber webs were measured using interdigitated metallic electrodes patterned substrates. The ESM conversion from a bio-waste into new value-added nanomaterials is very attractive from the sustainability and recycle waste perspective, the ZnO-based fibrous architectures featured by a large specific surface area having potential applications in water purification, photocatalysis or chemical sensors areas.

“…Chicken eggs are extensively consumed as they are nutritious, resulting in high costs of mass disposal of eggshells with membranes as industrial waste and garbage [ 12 , 13 ]. Recently, to reduce the costs of mass disposal, ESM has been recycled for various materials, such as the membrane of PEFCs [ 14 ] and absorbents [ 15 , 16 , 17 , 18 , 19 ], due to its nanoporous structure composed of protein fibers with abundant amines and amides. In addition, tar dyes contain abundant sulfonic acid and hydroxy groups, suggesting that dye-absorbed ESM (dye–ESM composite) shows higher proton conductivities and enhanced current density compared to pristine ESM [ 7 , 20 ].…”

Recently, polymer electrolytes have been developed for high-performance and eco-friendly fuel cells. Among the candidates, eggshell membrane (ESM) has been promising because of its abundance to assemble various energy devices with low cost and its absorption ability of organic materials. In this work, we investigated fuel cells that included ESM-absorbing xanthene-, triphenylmethane-, and azo-type tar dye, which contained abundant hydrophilic groups, as polymer electrolytes. We found out two points: (1) that the fuel cells that included ESM-absorbing xanthene-type dye generated the highest I–V performance, and (2) the basic molecular structures of the tar dyes determined the correlation of the maximum power and proton conductivities.
