“…1. Each of these membranes is composed of protein fibers that are arranged to form a semi-permeable membrane, producing an intricate lattice network of stable and water-insoluble fibers and has high surface area resulting in various applications such as adsorbent [111,[117][118][119][120][121][122] and supporting medium for enzymes immobilization [123][124][125].…”

As the current global trend towards more stringent environmental standards, technical applicability and cost-effectiveness became key factors in the selection of adsorbents for water and wastewater treatment. Recently, various low-cost adsorbents derived from agricultural waste, industrial by-products or natural materials, have been intensively investigated. In this respect, the eggshells from egg-breaking operations constitute significant waste disposal problems for the food industry, so the development of value-added by-products from this waste is to be welcomed. The egg processing industry is very competitive, with low profit margins due to global competition and cheap imports. Additionally, the costs associated with the egg shell disposal (mainly on landfill sites) are significant, and expected to continue increasing as landfill taxes increase. The aim of the present review is to provide an overview on the development of low-cost adsorbents derived from eggshell by-products.

“…The adsorbability of gold ions may be influenced by changes in the pH of the solution. Suyama et al 3 examined the adsorbability of gold ions on ESM powder. The gold ion uptake on ESM was greatest at pH ϭ 4.…”

“…Earlier research had shown that ESM accumulates and eliminates various heavy metal ions from dilute aqueous solutions with a high affinity and in a short contact time, depending on the pH and other characteristics of the individual ion. 3 However, competitive adsorption experiments have never been performed in mixed solutions containing various metal ions. In addition, the application of chitosan to industrial use has attracted much attention owing to its availability, low cost, and biodegradability.…”

We have successfully prepared a bead-type adsorbent from two materials with different adsorption characteristics. Heavy metals were removed by greatly swollen egg shell membrane-conjugated chitosan beads. The egg shell membrane accumulated and removed precious metal ions from a dilute aqueous solution with a high affinity in a short contact time. Experiments suggested that chitosan beads could take up gold ions with great capacity and selectivity by conjugation with egg shell membrane. Under certain conditions, the selective removal of gold and copper in a mixture of gold and copper ions by egg shell membraneconjugated chitosan beads was 100% and 2%, respectively. Egg shell membrane-conjugated chitosan beads can be seen as a promising material to recover gold in wastewater from various industries, such as electroplating.Key words Chitosan beads · Egg shell membrane · Heavy and precious metal · Selective recovery for metal

“…This may well occur in the two outermost (not eroded in the course of embryonic development) layers of the avian eggshell, i.e., the palisade layer and cuticle. In contrast to eggshells, the shell membrane thickens during embryonic development (Castilla et al 2010b) and exhibits a high binding affinity for a variety of heavy metals (Suyama et al 1994;reviewed in Richards 1997). Furthermore, since phosphorus and magnesium are concentrated mainly in the external eggshell layer (Cusack et al 2003;Rodriguez-Navarro et al 2013), whereas calcium is deposited in the mammillary layer (substantially eroded during embryonic development; reviewed in Hincke et al 2012), it may be assumed that some portion of Pb and Zn (their chemical properties are similar to those of Ca) could be deposited in the mammillary layer of a shell.…”

The pattern of distribution and interaction of metals and calcium in eggshells and egg contents in relation to the embryonic development of eggs in a small passerine bird

Differences in element concentrations have been observed between embryonated and non-embryonated eggs of the Eurasian Reed Warbler Acrocephalus scirpaceus, presumably due to the resorption of calcium and other elements from the shell. To investigate this difference, we tested the hypotheses that (1) the distribution of elements in eggshells and egg contents, (2) the individual element-element relationships between shells and contents, and (3) the relationships among the elements in eggshells and egg contents vary between the two egg samples. Based on the levels of 11 elements (Cr, Cu, Ni, Cd, Pb, Mn, Fe, Co, Zn, Mg and Ca) in Reed Warbler eggs, our results confirmed the second and third hypotheses. Importantly, we found that embryonic development tended to blur the lines between two types of relationships: (1) between elements in eggshells and egg contents through an increase in the number of significant correlations, some of which may be enhanced by high levels of certain elements (Cd, Co, Pb, Zn are indicative of trace metal pollution in fish ponds); (2) among the various elements in eggshells and egg contents, as demonstrated by the differential grouping of elements in principal components analysis (PCA). The consistent positive direction of relationships for almost all elements in both the shells and contents of eggs is presumed to result from the initial parallel co-sequestration of all the elements which accompanies intensive calcium transfer from the female body into the incipient egg. Our study highlights the fact that only limited inferences can be drawn from the interactions of metals and calcium in eggshells and egg contents if the fertility status of the eggs is unknown.
