“…Bone scaffolds are composite materials that can be fabricated using polymers, ceramics, or metals [ 11 ], as typified by a recently developed magnesium-based scaffold [ 12 ]. Polymers constitute reliable and versatile materials for fabricating bone scaffolds, primarily due to their broad biodegradation tunability, surface-to-volume ratio, heterogeneous porosity, and mechanical characteristics [ 13 , 14 , 15 , 16 ]. Polymeric materials also have considerable design potential arising from simple customization of their chemical and structural properties.…”

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.

“…The use of polymer matrix composite materials reinforced with glass fiber and carbon fiber materials has been able to replace some metal and wood materials since the development of composite materials began in the middle of the last century, [1,2]. However, the use of polymer composite materials reinforced with artificial fibers is considered environmentally unfriendly [3,4] because the material is not able to decompose naturally or non-biodegradable [5].…”

Studies in this paper relate to the development of composite materials. Special attention is given to the development of polymer composite materials which are reinforced with natural fibers. At present a very intense investigation using local materials sources. This paper presents an analysis of surface fractures caused by Charpy impact and tensile loading. Specimens prepared in this study used polyester resin 85% by weight, and areca nut fiber which has been boiling with 100oC of boiling water for 6 hours of 15% by weight. The making of polyester matrix composite material with areca nut fiber reinforcement material that has undergone physical treatment is done by mixing. This mixture was entered into the mold that has been prepared for the tensile test specimen and impact test specimen. The mold that has been filled with the composite material is pressed with a high-pressure press to get a solid composite material and reduce cavities. Fracture surface of specimens due to impact tests and tensile tests are examined using a scanning electron microscope. The results of the analysis of the fracture surface in tensile loading showed that the fiber was broken evenly with the matrix breaking. While the fracture surface that occurs in the tensile loading shows a very fibrous fracture surface where the broken fiber is not on the broken surface but as if it was pulled from the matrix. On the fracture surface the tensile test and impact test specimens reveal very little cavities and the visible gaps between the fiber and the matrix are very small. This shows the bond between the fiber matrix is good.

The practice of using a massive amount of environmental unfriendly and toxic petroleum-based materials in tissue engineering and biomedical fields demands the materials, which are biodegradable, renewable, environmentally friendly, biocompatible, and bioactive. So, renewable polymers have got considerable attention due to their numerous desirable properties. The nanofibers that are prepared from renewable materials and their blends can integrate the properties of both nanofibers and renewable polymers. Development of scaffolds that mimic the construction of tissues at nanoscale is a great challenge for tissue engineering. Electrospinning is the most promising technique for nanofibers formation. Nanofibers provide a platform for cell adhesion, proliferation, and differentiation. Therefore, nanofibers from sustainable materials have been used in tissue engineering and biomedical fields. In this review, methods for nanofibers fabrication, sustainable nanofibers made from natural and synthetic polymers and their applications in tissue engineering and biomedical field, have been emphasized.
