“…erefore, decrease in MB concentration in solution observed in raw egg shell powder and calcined egg shell powder under dark could be due to physical adsorption, which is in accordance with the work of Tsai and coworkers [32,45]. Furthermore, the work of El-Kemary and coworkers on TiO 2 /egg shell nanocrystals reported increasing removal efficiency when the calcination temperature is increased from 400°C to 900°C for the acid red nylon 57 dye [39]. erefore, the enhanced dye degradation of CESP compared to RESP is in agreement with the above data.…”

“…ere have been studies conducted for the use of egg shell powder and egg shell membrane for dye removal [32][33][34][35][36][37][38]. Furthermore, egg shell powder has been used to develop several composite materials for dye removal incorporating TiO 2 , polymer, and clay materials [39][40][41][42]. ere is a significant enhancement in dye removal activity observed for egg shell powder composites compared to egg shell powder alone [39][40][41][42].…”

This study is focused on removal of dyes in water bodies using calcined egg shell powder obtained from waste egg shells as a new material for photocatalytic dye removal. The photocatalytic activity of calcined egg shell powder (CESP) was compared with the raw egg shell powder (RESP) under light and dark conditions. The results reveal that CESP has significantly a higher dye degradation capability of 80% compared to the RESP which is 20% under the same condition. Furthermore, under light conditions, CESP has shown nearly 50% increase in dye degradation compared to the same material in the dark. The kinetics of dye degradation follows pseudo-second-order kinetics suggesting the chemisorption process and the Freundlich adsorption isotherm is best fitted (R2 value is 0.96 for the linear fit) with the dye adsorption process. The application of CESP in industry is studied with a textile acid dye Lanasyn Rez F5B, and the results reveal it follows pseudo-second-order kinetics in dye removal.

“…Nanotechnology is a trend in many applications [28][29][30][31]. Pure CaO is used in many applications, such as the cement industry, biodiesel production, the petroleum industry, electric lighting, paper industry, and power production [32][33][34][35][36][37][38]. There are many sources available to prepare CaO nanoparticles, such as using chicken eggshells (with very low quantities) or any source rich in calcium carbonate, such as CMW sugar cane waste, before treatment.…”

Large amounts of carbonated mud waste (CMW) require disposal during sugar manufacturing after the carbonation process. The lightweight of CMW enables its utilization as a partial replacement for the cement to reduce costs and CO2 emissions. Here, various levels of CMW, namely, 0, 5, 10, 15, 20, and 25 wt.% were applied to produce composite cement samples with ordinary Portland cement (OPC) as a regular mix design series. Pure calcium oxide (CaO) nanoparticles were obtained after the calcination of CMW. The techniques of X-ray fluorescence spectrometers (XRF), Transmission electron microscope (TEM), Selected area diffraction (SAED), Scanning electron microscope (SEM), energy dixpersive X-ray (EDX), and dynamic light scattering (DLS) were used to characterize the obtained CaO nanoparticles. According to the compressive strength and bulk density results, 15 wt.% CMW was optimal for the mix design. The specific surface area increased from 27.8 to 134.8 m2/g when the CMW was calcined to 600 °C. The compressive strength of the sample containing 15% CMW was lower than the values of the other pastes containing 5% and 10% CMW at all of the curing times. The porosity factor of the hardened cement pastes released with a curing time of up to 28 days. Excessive CMW of up to 25 wt.% reduced the properties of OPC.

Over the past century, the world's population has increased greatly. The growth in the population has increased the global food demand, so the food sector has increased its production. As a result of the increased production and consumption, a huge amount of agro-food waste is being generated yearly. Rice husk, wheat straw, sugarcane bagasse, corn husk, peanut shell, eggshell, are just a few examples of agro-food wastes. As these agro-food wastes and their by-products are left unused and unattended, their amount is increasing globally. It is imperative to find ways to put these wastes to environmentally viable use. These wastes find direct uses in biofertilizers, mud houses, animal feed, biofuel, and heat generation in small-scale industries, etc. After heat generation, ashes are considered as a secondary by-product, which can be used as a sustainable and renewable resource for synthesizing value-added products for various applications. This article presents a review of the traditional and advanced methods of utilizing these wastes in household applications, animal feed, fertilizers, fuel generation, pyrolysis, and for the removal of toxic metals from polluted water. These secondary resources can also be used in construction materials and for the synthesis of glasses and glass-ceramics, which can be used in bioengineering, optical, and dielectric materials. Agrofood wastes can be used as resource materials to develop modern materials with better properties instead of using minerals. This not only reduces the environment-and management-related problem of the wastes but also provides a sustainable alternative way to produce cost-effective value-added materials for the benefit of society.
