“…The non-chemical separation methods for separating the membrane from the eggshell include manual scraping and peeling (Haddad et al, 2021;Hussain et al, 2010;Kulshreshtha et al, 2020;Torres-Mansilla & Delgado-Mejía, 2017), mechanical methods include cyclone, venturi, and dissolved air floatation (Nurdin et al, 2018). The chemical separation is mainly through acid dissolution (Torres-Mansilla & Delgado-Mejía, 2017), microwave treatment (Hussain et al, 2010), proteolytic enzymes, etc.…”

Eggshell is the most abundant agricultural (hatchery) and industrial (confectionary) natural waste approximately reaching up to 50000 tons per year and is a threat to the environment and the public. Eggshell membrane and shell waste can be used for biomedical and industrial applications as value-added products. Hence, a scoping review was planned to understand the present scenario and knowledge gap; it also explored eggshell membrane separation methods available commercially for the routine utility to understand the knowledge gap. A systematic search was performed in PubMed, Scopus, and ProQuest databases using Eggshell/Eggshells/Egg shell, Membrane, Separation/separator as keywords with and/or as Boolean operators within the field of title, abstract, keywords. The search was done from the period of inception (as per the database) till 4th October 2021 and a total of seven full-text articles were included in the review. The methods mentioned in the literature were Microwave treatment, Acid Dissolution, Dissolved Air Floatation, using proteolytic enzymes, and grinding followed by mechanical agitation. This research concludes that no equipment is commercially available. Hence there is a need for technology development as the majority of publications mentioned manual peeling, Microwave treatment, acid dissolution, dissolved air floatation, grinding, and mechanical stirring as the methods at laboratory scale.

“…Other less commonly used chemicals, e.g., n-butyl acetate, have been considered [ 74 ]. Chemical treatment affects protein bonds and has an impact on the structural integrity and chemical properties of the membrane [ 78 ]. In addition, previously published research has not established the minimum solution concentration, time, and temperature to dissolve a given amount of eggshell.…”

Eggshell Membrane as a Biomaterial for Bone Regeneration

The physicochemical features of the avian eggshell membrane play an essential role in the process of calcium carbonate deposition during shell mineralization, giving rise to a porous mineralized tissue with remarkable mechanical properties and biological functions. The membrane could be useful by itself or as a bi-dimensional scaffold to build future bone-regenerative materials. This review focuses on the biological, physical, and mechanical properties of the eggshell membrane that could be useful for that purpose. Due to its low cost and wide availability as a waste byproduct of the egg processing industry, repurposing the eggshell membrane for bone bio-material manufacturing fulfills the principles of a circular economy. In addition, eggshell membrane particles have has the potential to be used as bio-ink for 3D printing of tailored implantable scaffolds. Herein, a literature review was conducted to ascertain the degree to which the properties of the eggshell membrane satisfy the requirements for the development of bone scaffolds. In principle, it is biocompatible and non-cytotoxic, and induces proliferation and differentiation of different cell types. Moreover, when implanted in animal models, it elicits a mild inflammatory response and displays characteristics of stability and biodegradability. Furthermore, the eggshell membrane possesses a mechanical viscoelastic behavior comparable to other collagen-based systems. Overall, the biological, physical, and mechanical features of the eggshell membrane, which can be further tuned and improved, make this natural polymer suitable as a basic component for developing new bone graft materials.

“…In addition, the eggshell membrane produced could be uniformly ground to the particle size required for the preparation of carriers for lipase immobilization. One of the most important facts related to the separation of eggshell membranes from eggshells by acids is that exposure of eggshell membranes to acids leads to changes in their chemical composition (compared to the untreated membrane) [97,98]. However, there are no data in the literature to date discussing the effects of various acid-induced changes in eggshell membrane composition on enzyme immobilization efficiency.…”

One of the major challenges in sustainable waste management in the agri-food industry following the “zero waste” model is the application of the circular economy strategy, including the development of innovative waste utilization techniques. The conversion of agri-food waste into carriers for the immobilization of enzymes is one such technique. Replacing chemical catalysts with immobilized enzymes (i.e., immobilized/heterogeneous biocatalysts) could help reduce the energy efficiency and environmental sustainability problems of existing chemically catalysed processes. On the other hand, the economics of the process strongly depend on the price of the immobilized enzyme. The conversion of agricultural and food wastes into low-cost enzyme carriers could lead to the development of immobilized enzymes with desirable operating characteristics and subsequently lower the price of immobilized enzymes for use in biocatalytic production. In this context, this review provides insight into the possibilities of reusing food industry wastes, namely, eggshells, coffee grounds, and brown onion skins, as carriers for lipase immobilization.
