“…Sugarcane bagasse can be used by the paper and pulp industry as a raw material to make paper. The residues of castor, if used in the paper and pulp industry, would increase the earnings of castor-growing farmers and provide raw material to an industry that is otherwise dependent on forest, agro-forestry, and agro-based byproducts for its raw materials [56]. GCH-7 castor stem contains 45.7% cellulose and 17.2% lignin.…”

Due to their higher specific area and, in most cases, higher adsorption capacity, nanomaterials are noteworthy and attractive adsorbents. Agricultural products that are locally available are the best option for removing methylene blue (MB) dye from aqueous solutions. Because it is self-anionic, FT-IR and SEM investigations of biosorption have confirmed the role of the functional group and its contribution to the formation of pores that bind cationic dye. It is endothermic if the adsorption of MB by an adsorbent is high as the temperature increases; on the other hand, exothermic if it is high as the temperature decreases. A basic medium facilitates adsorption with respect to pH; adsorption is proportional to the initial concentration at a certain level before equilibrium; after equilibrium, adsorption decreases. A pseudo-second-order model applies for certain agricultural products. As per plotted graph for the solid-phase concentration against the liquid-phase concentration, the Langmuir adsorption isotherm model is favored; this model describes a situation in which a number of molecules are adsorbed by an equal number of available surface sites, and there is no interaction between adsorbate molecules once all sites are occupied. In contrast, the Freundlich model depicts non-ideal multi-layer sorption onto heterogeneous surfaces via numerical analysis; with a value of n = 1, the result is a linear isotherm. If the value of n < 1 or n > 1, then it is chemical or physical adsorption, respectively. Based on an EDX analysis, relevant elements are confirmed. BET analysis confirms the surface area. Nanoproducts categorized as agricultural products exhibit the aforementioned tendency. Even though nanoparticles show positive outcomes in terms of higher adsorption, a high specific area for the targeted pollutant is needed in real-world applications. In the relevant sections herein, the behavior of thermodynamic parameters, such as enthalpy, entropy, and Gibbs free energy, are examined. There is some question as to which form of agricultural waste is the most effective adsorption medium. There is no direct answer because every form of agricultural waste has its own distinct chemical and physical characteristics, such as porosity, surface area, and strength.

Castor shell is rich in lignin material and takes a long time to decompose. Therefore, it is necessary evolveprocedures that can hasten this process so that the shell could be used as compost. The compost heaps were prepared in four treatment combinations (T1: castor shell + 10% dung slurry; T2: castor shell + dung slurry + 2% urea solution + 0.5% SSP; T3: castor shell + dung slurry + microbial consortium @ 1 kg/t; and T4: castor shell + dung slurry + 2% urea solution + 0.5% SSP + microbial consortium @ 1 kg/t. The N (1.2%) and P (1.4%) in T4, and K (1.5%) T1 were maximum. Micronutrients, Fe (4000 ppm) in T3 and Zn (68 ppm) in T4 were maximum.
