Interest in sustainable, biodegradable materials for environmental restoration has increased due to rising water pollution levels and the depletion of fossil fuel resources. Due to their high lignocellulosic biomass content, agricultural wastes like rice husk, sugarcane bagasse, maize cob and coconut husk are interesting feedstocks for biodegradable polymers. This study examines current methods for turning agricultural waste into biodegradable polymers and assesses how well they work in water purification applications. Synthesis pathways, material characterization, pollutant removal techniques, and environmental benefits are highlighted. The conversion of agricultural waste into biodegradable polymers for environmental applications has attracted a lot of attention due to the growing global demand for sustainable products and clean water. The extraction of cellulose from rice husk and sugarcane bagasse, its chemical conversion into carboxymethyl cellulose (CMC), and the creation of CMC–Chitosan and biochar-based composites for water filtration are the main topics of this work. Due to improved functional groups and synergistic polymer interactions, experimental analyses showed that the CMC–Chitosan composite had the maximum adsorption capacity of 112.4 mg/g for methylene blue dye. Adsorption efficiency was highly pH-dependent, with optimal removal occurring close to neutral conditions, and kinetic analysis showed pseudo-second-order behavior. Results confirm that agricultural waste-derived polymers provide an efficient, low-cost, and biodegradable alternative to synthetic adsorbents. This research establishes a foundation for scaling bio-based polymeric materials for sustainable water treatment systems.
