Designing new engineered materials derived from waste is essential for effective environmental remediation and reducing anthropogenic pollution in our economy. This study introduces an innovative method remediating metal-contaminated water, using two distinct types: one biowaste (eggshell) industrial (fly ash). We synthesized three novel, cost-effective nanoadsorbent types, including tertiary composites biopolymer-based (specifically k-carrageenan chitosan), which targeted chromium removal aqueous solutions. SEM analysis reveals that the first composite, EMZ, zeolite, magnetite nanoparticles are successfully integrated into porous structure of eggshell. In second composite (FMZ), fly ash particles similarly loaded within zeolite pores. Each by incorporating corresponding (FMZ or EMZ) biopolymer framework. Structural modifications eggshell, chitosan, resulted notable increases specific surface area, as confirmed BET analysis. These enhancements significantly improve adsorption efficiency each adsorbent type developed. The performances achieved follows: EMZ (89.76%), FMZ (84.83%), EMZCa (96.64%), FMZCa (94.87%), EMZC (99.64%), FMZC (97.67%). findings indicate across all types occurs via a multimolecular layer mechanism, characterized spontaneous endothermic. Desorption studies further demonstrate high reusability these nanomaterials. Overall, this research underscores potential utilizing performant low-cost biocomposites bioremediation applications.
