        abstract = {The rising demand for renewable energy sources has driven significant research into biodiesel and bio-derived additives. Sulfonated resin catalysts, characterized by their robust acidic functionalities and stability, have emerged as promising materials for these processes. This review highlights recent advancements in the design, functionalization, and application of sulfonated resin catalysts in biodiesel production and the synthesis of bio-derived additives. Innovations in catalyst development, including the incorporation of hierarchical structures, enhanced thermal stability, and multifunctional active sites, are discussed. Furthermore, the challenges and future opportunities in scaling up and optimizing these catalysts for industrial applications are outlined. This review highlights the application of various Amberlyst resins (e.g., Amberlyst-15, Amberlyst-36, Amberlyst-46) in catalyzing transesterification reactions involving non-edible oils. Key parameters such as catalytic efficiency, reaction conditions, and reusability are discussed. A comparative evaluation underscores their potential in overcoming challenges posed by high free fatty acid content in feedstocks.},
