The catalyst was synthesized by first preparing NiO/γ-Al₂O₃ via dry impregnation of nickel onto a γ-Al₂O₃ support, followed by grafting with 3-aminopropyltrimethoxysilane (3-APTMS) to form NiO/γ-Al₂O₃-NH₂. The dual functionality, arising from the incorporation of NiO and amino groups, is designed to enhance reactant adsorption and improve catalytic efficiency. This innovative design addresses limitations of conventional catalysts by improving the interaction between active sites and reactants.The catalyst was initially evaluated for basicity using titration and characterized by FTIR and XRD, confirming the formation of NiO rather than Ni(OH)₂. The sample with the highest basicity was further analyzed using surface area analysis and SEM-EDX to determine its textural properties and elemental composition. The mesoporous, amorphous NiO/γ-Al₂O₃-NH₂ exhibited a surface area of 91.68 m²/g, a pore volume of 0.16 cm³ /g, and an average pore diameter of 3.03 nm.

The global generation of waste tires, which can have detrimental environmental effects when burned, necessitates innovative recycling methods. Recycling rubber reduces the demand for new raw materials, conserves natural resources, and lowers greenhouse gas emissions. This study explores using shredded waste tires (including powder, fiber, 0.5–2 mm and 2.5–3.5 mm granules, and Tire-derived fuel) as adsorbents for oil spill cleanup. Shredded tire particles, with their large surface area, porosity, hydrophobicity, and durability, are highly effective in oil adsorption. Optimal oil removal was achieved using a 2 g adsorbent dose, an initial oil concentration of 40 g/L, a 30-minute shaking time, a pH of 7, and a temperature of 25°C. Tire powders demonstrated exceptional efficiency, achieving an oil removal rate of 98.1 %. The adsorbent’s high reusability, maintaining a 70.1 % oil removal percentage after 20 cycles, underscores its cost-effectiveness and environmental benefits. Batch adsorption experiments indicated that the process follows second-order kinetics and fits the Freundlich isotherm model. The maximum adsorption capacity was 15.44 g/g.

In step 1, GCSM categories and criteria were evaluated using the Randomized Weighted Fuzzy-Analytical Hierarchy Process (RWFAHP, 2024) through the national experts' viewpoints. Step 2 applied the Fuzzy Delphi method (FDM) to find key factors for evaluating emerging GCSM technology alternatives.

For robust assessment, MCDM methods including RAWEC (2024), CRADIS (2022), MARCOS, COCOSO, CODAS, VIKOR, and TOPSIS were employed.

For an illustrative example, the Goharzamin mine was selected to obtain the optimal technology for the reduction, reuse, and recycling of iron ore overburden (IOO) residues.
