“…Several authors like Ghabeer [5], Toro [6,7] and Kang [8] have replaced the mineral calcium carbonate by ES developing bio-compounds. Others like Ramdani [9] and Fombuena [10] have used other natural sources in order to obtain the calcium carbonate.…”

In this investigation a fully biobased composite material has been obtained using a biobased polyethylene obtained from sugar cane as matrix and eggshell (ES) as filler. ES was studied in order to replace mineral carbonate calcium as polymer filler, which is commonly used. In order to do this the ES has been chemically modified and then its potential for the development of a biocomposite was evaluated. The filler adhesion to the polymer matrix has been improved using titanate particle treatment which has been chosen between silane and zirconate. The use of titanate as coupling agent enlarges the range of operating temperatures and also improves the interfacial bonding as it is displayed in impact fracture surface. Mechanical, thermal and rheological analysis were carried out in order to analyze the effect of the modified ES loading percentage. Thermal analysis showed a proportional effect of the filler load over the degradation temperature and an inversely effect over the enthalpy. Effect of the modified ES content on mechanical properties of PE/ES was also studied. The results showed that the modified CaCO3 can effectively improve the mechanical properties of bio PE, improving stiffness, hardness, flexural and tensile modulus. The amount of filler increases the viscosity, this fact specially hinders the processing processes which work with low shear rates.

“…Eggshell was also used in many applications such as filler in polymer, low-cost absorbent and a catalyst for biodiesel production because of its many valuable organic and inorganic components. Eggshell has been applied as a filler for polymer composites [4] and offered as an alternative to expensive activated carbon as a low-cost absorbent. Many researchers have proposed the effectiveness of using eggshells for heavy metal sorption such as Cu, Cr and Cd [5][6][7][8] and for the removal of dye effluents [9,10].…”

“…Till now, the utilization of eggshell calcium carbonate has been investigated as additive for animal feed 12 , human nutrition 13 , coating pigments for ink-jet printing paper 11 , natural absorbent of heavy metals 14 , dye-effluents remover 15 , bone substitute 16 and bio-filler for polymer-based composites. [17][18][19] The effects of fillers on the functional properties of the composite materials depend on shape, size, surface characteristics and degree of dispersion. Previously it has been reported that composites with nanoparticles showed better properties than composites with microparticles of the same filler.…”

A bio-derived and eco-friendly hybrid nanocomposite was developed from soy protein and eggshell nanopowder (ESNP). ESNP was synthesized via size reduction of chicken eggshells using ball milling followed by sonochemical process. Transmission electron microscopy and X-ray diffraction (XRD) studies revealed calcite particles in ESNP with size ranging between 20 and 40 nm. A trace of protein with as-synthesized ESNP was detected through X-ray photon spectroscopy (XPS) observation. Dispersion of ESNP in water was achieved by using a poly-anionic dispersant via adsorption mechanism. Green nanocomposites were developed from soy protein isolate (SPI) and dispersed ESNP using glycerol, a natural plasticizer, by solution casting process. Significant improvements in Young's modulus, tensile strength and thermal stability of SPI nanocomposite sheets were achieved as a result of incorporation of well-dispersed ESNP. The developed ESNP-incorporated SPI nanocomposite would be inexpensive and useful to fabricate sustainable 'green' composite structures.
