“…The organic matter of eggshell comprises various functional groups, such as hydroxyl, amine, and carbonyl groups. When the eggshell powder was mixed with the dye solution, calcium salts may partially dissolve and release Ca 2+ , HCO 3 − , CO 3 2− and OH − ions, which can form a negatively surfaced charge 54,55 . In acidic media (HCl), the eggshell surface exhibits a positive charge, so there is a high electrostatic attraction between the eggshell powder and the anionic, negatively charged dye (this dye contains aromatic rings such as phenolic OH and sulfonate SO 3 − groups that ionize in aqueous solution and form coloured anions 49 ).…”

Based on the well-known excellent adsorbent ability of chicken eggshells, the adsorptive capacity and mechanism of Remazol Brilliant Violet-5R (RBV-5R) dye by eggshell was investigated. Exploiting the high surface-area-to-volume ratio and porous structure of this natural adsorbent, the developed procedure showed to be useful for the efficient adsorption of RBV-5R dye from contaminated water. The protocol was thoroughly optimized by investigating the effect of the dye concentration, biomasscontaminated water ratio, particle size of the adsorbent, pH and temperature, as they are key factors in the efficiency of the dye removal process. The eggshell material was characterized by different types of microscopy techniques (stereo, polarization, SEM) as well as elemental analysis (element distribution mapping, EDX), Raman spectroscopy and BET-surface density measurements. EDX, FTIR and Raman spectroscopy proved the presence of the adsorbed dye on the surface of the biomaterial. It was shown that under optimal conditions, the environmentally friendly and inexpensive eggshell could be a reliable adsorbent for Remazol dye removal from wastewater. One of today's global challenges is to supply healthy, pure and consumable water to safeguard public health since a growing variety of toxic organic and inorganic pollutants are occurring in water bodies 1. According to the 2015 World Water Development Report, the demand for water around the world will increase by 55% over the next 15 years, indicating that the Earth's current water supplies can cover only 60% of our future needs by 2030 2. With rapid industrial development, the overexploitation of natural resources, industrial and natural disasters, the number of polluted water sites contaminated with heavy metals 3-6 , radioactive elements 7,8 , nitrite 9,10 , phosphate 11,12 , pesticides 13 , dyes 14-16 , etc., are continuously increasing. Dyes are widely utilized in the paper, pulp, paint and textile industries, with a large amount of water demand for washing and cleaning purposes. Based on the Colour Index, currently, more than 10 000 various types of synthetic dyes are available worldwide. In 2014, more than 1.5 million tons of dyes were produced annually. Fifty percent of these dyes are used by the textile industry, where during the colouring process, 1-10% of these dyes are discharged 17,18. Due to the high solubility and low biodegradability of these compounds, dye-polluted industrial wastewater is one of the most difficult types of wastewater to clean. Remazol Brilliant Violet-5R (RBV-5R), a reactive dye, is used to colour cellulosic fibres. After the colorization process, approximately 10-50% of the initial dye load remains unused 19. Biosorption is a promising method for removing persistent compounds, i.e., non-biodegradable compounds. Recently, various materials such as nanocomposites, households and industrial wastes have been used as biosorbents for inorganic and organic contaminant removal 5,11,20,21.

“…75 found that industrial waste ES could be used as an adsorbent for methylene blue (MB) and Congo red dyes. The effect of ES in binding three different dyes, methylene blue, bromophenol blue, and methyl orange from their aqueous solutions has also been studied 76. It has been concluded that ES can act as an effective adsorbent for removing anionic and cationic dyes.…”

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.

Dyes, especially from textile industries, are significant pollutants in water and wastewater, which have become pervasive in the environs to which they are discharged. The effluents containing different types of dyes have become ubiquitous in the environment. While several treatment techniques have been developed to address the removal of recalcitrant dyes from water and wastewater, the adsorption technique is highly preferred due to its many advantages. However, selecting the appropriate alternative adsorbents with high adsorption capacity to costly activated carbon has continued to receive great attention. This book chapter reviewed the applicability of adsorptive techniques of agro-waste based adsorbents for the removal of dye pollutants from water and wastewater. The mechanisms of persistent dye pollutant removals based on the adsorption processes were adequately described. Further, the strengths, weaknesses, opportunities and threats (SWOT) of using agro-waste materials as alternative adsorbents are also accounted.
