Natural zeolites, crystalline aluminosilicates found in volcanic and sedimentary deposits, are widely used in water purification, gas separation, catalysis and soil amendment. Their high cation exchange capacity and selective adsorption properties make them valuable, but impurities, variability, and limited tunability hinder their widespread industrial use. Researchers are exploring biomass-derived zeolites as a sustainable alternative to address these challenges. Utilizing agricultural and industrial waste aligns with circular economy principles by converting waste into valuable materials. Agricultural residues, forestry waste, and industrial by-products can serve as substitutes for conventional raw materials like kaolin and aluminosilicates. Standard synthesis methods include hydrothermal, alkali fusion, and solvothermal techniques, using activators like NaOH and KOH to facilitate crystallization. Synthesized zeolites offer economic and environmental benefits by reducing waste, lowering costs, and minimizing reliance on non-renewable resources, while demonstrating strong potential in catalysis, adsorption, and wastewater treatment. However, challenges remain in optimizing synthesis efficiency, scalability, and purity. Future research should focus on refining process parameters, enhancing yield, and exploring novel sources to improve performance. Sustainable zeolites represent a transformative approach for merging waste management with industrial applications to create a greener, more resource-efficient future.
