“…A review of the literature reveals that the use of eggshell waste materials in their natural as well as chemically modified forms have provided excellent results for the removal of various classes of dyes [20,21], oxalic acid [22], phenols [23,24], pesticides [25], humic acid [26], heavy metals [27,28] fluorides [29], Phosphorous [30] and PAHs [31]. Most of these applications were tested on batch experiments and focused on synthetic wastewater; Limited work has been reported for the applicability of eggshell materials for the treatment of real wastewater or more specifically for the treatment of municipal landfill leachate [32].…”

A sequential treatment consisting of coagulation/flocculation followed by transport column experiment was adopted and used in this work for the treatment of landfill leachate containing phenols and polycyclic aromatic hydrocarbons (PAHs). Coagulation experiment was performed in a standard jar test apparatus using alum as coagulant material. In column experiments, natural eggshell material was used as filter media after calcinations at 750<sup>o</sup>C either separately or combined with granular activated carbon (GAC). Alum addition at a predetermined optimum dose (3.5 g/L) caused a reduction in total suspended solids (TSS), chemical oxygen demand (COD), total phenols, and total (PAHs) by 82%, 32%, 24%, and 34% respectively. Specific PAHs analysis revealed higher binding affinity of more hydrophobic PAHs toward particles with 50% reduction than those of less hydrophobic PAHs with only 6% reduction. The results obtained from the transport column experiments indicate that calcined eggshell (ESC) particularly when applied as a mixture with GAC can be used as promising adsorbent for both phenols and PAHs. 95% of phenols and PAHs were removed during the first 1,500 pore volumes (PV) of column operation while > 80% were obtained at the end of the experiment (3,500 PV).

Chicken eggshell is one of the most common wastes generated from households, restaurants and other food processing outlets. Waste Chicken Eggshells (WCES) also constitutes an environmental nuisance and ends up discarded at dumping site with no consideration of further usage. The main constituent of WCES is calcium carbonate from which calcium or calcium oxide can be extracted for various applications. This current effort reviews recently published literature on the diverse applications of WCES. The considered utilization avenues include catalysts for biofuel production, construction industry, wastewater purification, industrial sector, food industry, medical, and agricultural applications. The specific areas of application apart from the transesterification reactions include cement additives and replacement in concrete, asphalt binder, adsorbent of metals and dyes, production of hydroxyapatite, food supplement and fortification, dentistry, therapeutics, bone formation, drug delivery, poultry feeds as well as organic fertilizer. For most of the identified applications, the WCES is subjected to pretreatment and other modification techniques before utilization. The conversion of WCES to valuable products is a cost-effective, safe, environmentally friendly, non-toxic and viable means of waste disposal and utilization. More investigations are needed to further explore the benefits derivable from this bioresource.

“…Por exemplo, Zhang et al (2022) biossintetizaram cascas de ovos de galinha, por decocção de chá, para obtenção de CaO e aplicação na produção de biodiesel. Ikram et al (2016) utilizaram cascas de ovos de galinha tratadas com água régia e n-hexano na adsorção de ácido oxálico de águas residuais, em que caracterizaram tal resíduo como excelente material de adsorção. Ge et al (2021) calcinaram as cascas de ovos de galinha para obter o CaO como catalisador e utilizá-lo nas reações com óleos de origem animal.…”

O consumo elevado de ovo de galinha produz diariamente toneladas de cascas de ovos, gerando um grave problema ambiental, uma vez que são descartadas de forma inadequada em aterros sanitários. Este resíduo é composto, em sua maior parte, por carbonato de cálcio (CaCO3), um precursor para a obtenção do óxido de cálcio (CaO). Assim, neste trabalho objetivou-se obter CaO a partir das cascas de ovos de galinha a fim de confirmar suas características como um biomaterial em função de análise estrutural, química e térmica para fins industriais, podendo ser aplicado na área da catálise. Para tanto, as amostras foram calcinadas em diferentes temperaturas (650, 700, 800 e 900 °C) com tempo de permanência de duas horas. As amostras in natura e sintetizadas foram analisadas por DRX, FTIR e TGA/DrTGA. Os difratogramas confirmaram a presença de CaCO3 como fase principal para as cascas de ovo in natura, sendo que para as amostras calcinadas em diferentes temperaturas ocorreu a formação CaO como fase principal. As bandas de absorção evidenciaram o aparecimento da ligação Ca-O para todas as amostras calcinadas. Além disto, para aquelas submetidas a 650 e 700 °C, foram ainda encontradas bandas de absorção de C-O, atribuídas à presença do CaCO3. As curvas termogravimétricas, por sua vez, mostraram que todas as amostras calcinadas se caracterizaram como estáveis, pois não apresentaram variação significativa em suas respectivas massas em função do tempo e temperatura programados. Desta forma, esse resíduo é uma excelente fonte alternativa e sustentável para a produção de CaO como biomaterial.
