“…A study of the removal of 2,6-Dimethyl phenol using CuO-Clinoptilolite composite showed an increased rate of degradation in comparison to pure CuO and was proposed to be due to the distribution of CuO particles on the zeolite particles thereby increased surface area of the photocatalyst [106]. Comparison of the degradation of Congo red dye using pure CuO and 1wt% CuO supported on eggshell (1wt%CuO/eggshell) catalysts under visible light for a period of 4 h and at similar other parameters showed an insignificant difference, that is 82% versus 80%, respectively [107]. It was proposed that the structural features and the correlation between the support eggshell and the active catalyst CuO gave rise improved rate of degradation and this strategy are also economically beneficial for the consumption of active catalysts can be lowered without causing significant loss in degradation efficiency.…”

“…For instance, Danish et al have reported the preparation of ZnO-CuO-supported on eggshell for photocatalytic degradation of dyes and organic compounds (Khairol et al, 2019a ). The designed material displayed good results for the degradation of methylene blue, congo red, and phenol, among others, suggesting that it could be effectively used for wastewater treatment (Khairol et al, 2019a , b ).…”

Eggshell waste is among the most abundant waste materials coming from food processing technologies. Despite the unique properties that both its components (eggshell, ES, and eggshell membrane, ESM) possess, it is very often discarded without further use. This review article aims to summarize the recent reports utilizing eggshell waste for very diverse purposes, stressing the need to use a mechanochemical approach to broaden its applications. The most studied field with regards to the potential use of eggshell waste is catalysis. Upon proper treatment, it can be used for turning waste oils into biodiesel and moreover, the catalytic effect of eggshell-based material in organic synthesis is also very beneficial. In inorganic chemistry, the eggshell membrane is very often used as a templating agent for nanoparticles production. Such composites are suitable for application in photocatalysis. These bionanocomposites are also capable of heavy metal ions reduction and can be also used for the ozonation process. The eggshell and its membrane are applicable in electrochemistry as well. Due to the high protein content and the presence of functional groups on the surface, ESM can be easily converted to a high-performance electrode material. Finally, both ES and ESM are suitable for medical applications, as the former can be used as an inexpensive Ca2+ source for the development of medications, particles for drug delivery, organic matrix/mineral nanocomposites as potential tissue scaffolds, food supplements and the latter for the treatment of joint diseases, in reparative medicine and vascular graft producing. For the majority of the above-mentioned applications, the pretreatment of the eggshell waste is necessary. Among other options, the mechanochemical pretreatment has found an inevitable place. Since the publication of the last review paper devoted to the mechanochemical treatment of eggshell waste, a few new works have appeared, which are reviewed here to underline the sustainable character of the proposed methodology. The mechanochemical treatment of eggshell is capable of producing the nanoscale material which can be further used for bioceramics synthesis, dehalogenation processes, wastewater treatment, preparation of hydrophobic filters, lithium-ion batteries, dental materials, and in the building industry as cement.

“…Therefore, in terms of ecology color removal processes enter into an important role in the treatment of wastewater containing high amounts of dyestuffs. Membrane [9], adsorption [10], electrochemical oxidation [11], coagulation [12], flocculation [13] and oxidation [14] methods were applied in the treatment of dye containing wastewater.…”

When the textile industry wastewater volume and considering the composition appears to be one of the most environmentally hazardous industries. Due to textile dyeing industry wastewater's basic properties, additional precautions are required besides conventional wastewater treatment to remove color. The most basic approach is to remove the wastewater colour and break down the chromophores and double bonds that make up the color by oxidative means. In this study, the treatability of wastewater containing Reactive Yellow 145 (RY 145) dyestuff by ozonation process has been investigated. The initial concentration of the wastewater containing RY 145 is 50 mg / L. In the study, pH, O3 dose and reaction time parameters have been studied in RY 145 dye removal. The most appropriate removal of RY 145 from wastewater have occurred at pH 5, 0.05 g / L.h O3 dose and 10 minutes reaction time. The removal efficiency of RY 145 has obtained as 99.07% under optimum conditions.
