“…Eggshell consists of 95% calcium carbonate (CaCO₃) as its main component and it is in the form of calcite. In CaCO3, calcite is the most stable component that forms elongated structures called columns, crystallite, or palisade [6]. Besides that, the remaining 5% of other inorganic materials in the eggshell are calcium phosphate, magnesium carbonate, and soluble and insoluble proteins.…”

This study summarizes the research on organic fillers, where eggshells were used as the reinforcement and banana peels as the matrix in the manufacturing of biocomposite thin film. Banana peel fibers exhibit a good characteristic of renewable material for the substitution of cement-based composites. However, biocomposite properties are limited by the poor adhesion between natural fiber interface and polymer matrix, which can be improved by chemical modification of fibers. In this research, banana peels were subjected to silane treatment. Biocomposite thin film manufacturing processes were carried out using blending and hand lay-up techniques with various concentrations of epoxy/waste banana peels/eggshell filler (EWE) ratios (EWE 0%, EWE 5%, and EWE 10%). X-ray diffraction (XRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and thickness swelling test were conducted on silane-treated and untreated banana peel biocomposite samples. In XRD analysis, it was found that EWE 10% sample had the highest crystallinity compared to EWE 0% and EWE 5%, and silane-treated samples had higher crystallinity than untreated samples. For FTIR test, lignin component was removed in silane treatment based on the changes of IR peak characteristic where the new bonds (-Si-O-C-, -Si-O-Si-, and -Si-C-) were found in treated samples. Besides, TGA results showed that the thermal stability of silane-treated samples was improved significantly with the increase of eggshell filler percentage, which was proven by the decrease in the decomposition stage. In thickness swelling test, the samples achieved higher swelling percentage as the percentage of eggshell filler increased. However, the decrease of 5–6% in thickness swelling of treated samples was possibly offset by the enhancement in fiber/matrix interfacial adhesion.

“…Nik Yusuf et al (2018) discutiram uma técnica para processamento de filme fino biopolímero usando resíduos de cascas de banana e CaCO3 extraído de resíduos de casca de ovo. A análise de DRX confirmou que este filme fino de biocompósito mostrou padrão amorfo de casca de banana e a presença de cobre, lítio e silício contém pequeno número de cristalinidade de 29,1%.…”

Este trabalho teve como objetivo definir o melhor solvente extrator e sistema de extração para determinação dos compostos fenólicos totais, capacidade antioxidante e antocianinas monoméricas totais do fruto do grumixama. Foram testados diferentes solventes (água, acetona, etanol e metanol), utilizados individualmente e em misturas, bem como diferentes sistemas de extração (agitação magnética à temperatura ambiente, agitação magnética sob refrigeração e escuro e banho ultrassônico à temperatura ambiente). Os resultados mostraram que a acetona / água (80:20, v / v) e a agitação magnética à temperatura ambiente maximizaram a extração dos compostos fenólicos totais e proporcionaram a maior capacidade sequestrante do radical DPPH.Para as antocianinas monoméricas totais, etanol 1,5 M HCl e metanol 1,5 M HCl demonstraram os melhores resultados como solventes de extração. Esses resultados indicam a influência de solventes e sistemas de extração aplicados no rendimento e qualidade dos extratos, além de reforçar o potencial da fruta grumixama em relação ao seu conteúdo fenólico e capacidade antioxidante.

“…The interaction between different elements of the brake pad material was seen in the range of 4000 to 500 cm -1 , indicating a band spectrum of banana fiber, eggshell, phenolic resin, and other elements. Based on the results of FTIR analysis, the five brake-pad specimens had absorption bands in the range of 3395-3000 cm -1 which is a characteristic of O-H stretching vibrations [26] (see Figures 2(a-e)).…”

The objective of this study is to develop a new environmentally-friendly brake pad made from eggshells (Es) and banana peels (BPs) as reinforcement agents. E and BP particles as dual reinforcement with various compositions were combined. The E/BP mixture was then embedded on a polymer matrix composing a resin/hardener mixture in a 1:1 ratio. As a standard, brake pads using a single reinforcement of E and BP particles were also fabricated. Physical properties (i.e. particle size, surface roughness, morphology, and density), as well as mechanical properties (i.e. hardness, wear rate, and friction coefficient properties) were investigated. It was observed that using dual reinforcements was preferable (compared to using single reinforcements) because they had a synergistic effect on the mechanical properties of the brake pad. The best mechanical properties were found in dual reinforcements of brake pad specimens using E/BP particles with a higher BP ratio in which the value of the stiffness test, puncture test, wear rate, and coefficient of friction were 4.5 MPa, 86.80, 0.093×10-4 g/s.mm2, and 1.67×10-4, respectively. A high BP particle ratio played a dominant role in dual reinforcements, increasing the resin's bonding ability and resulting in good adhesion between the reinforcement and matrix. When compared to commercial brake pads, the brake pad specimens fabricated in this study met the standards. The techno-economic analysis also confirmed the prospective production of brake pads from E and BP particles (compared to commercial brake pads). From this research, it is expected that environmentally friendly and low-cost brake pads can be used to replace the dangerous friction materials.
