Dye pollution is unsightly and harmful to the environment because it lowers oxygen levels in water and inhibits photosynthesis. The need for biodegradable polymers that can efficiently absorb pollutants is driven by the frequent failure of conventional treatment procedures to effectively remove dyes. The present study aimed to explore the applications of biodegradable natural components, including starch, cellulose, chitosan, and food waste derivatives, in removing dyes from wastewater. The review analysed relevant literature on biodegradable food materials for the removal of dyes from aqueous solution. The review articles were obtained through databases, including ScienceDirect, Scopus, PubMed, and Google Scholar. This review gathered relevant data, preferably from the last 10 years, on bioadsorbents for dye removal and waste management. Biodegradable adsorbents have shown great promise for dye removal due to their eco-friendliness, but their effectiveness depends on several factors. These include surface area, pH, and material modifications that enhance adsorption properties. Electrostatic interactions, ion exchange, hydrogen bonding, and π-π interactions play key roles in the dye adsorption process. Although these materials can be reused after dye removal, maintaining their efficacy over multiple cycles often requires chemical or thermal regeneration. Cost-effective scaling and the development of green regeneration techniques are still needed for practical applications. Dye removal is possible using biodegradable materials. Although these materials are effective with certain modifications, further research is needed to develop cost-effective scaling methods and environmentally friendly regeneration processes.
