<p>This study reported the synthesis of Pectin- Polyvinyl alcohol (PVA) hydrogels incorporated with Titanium dioxide (TiO₂) Nanoparticles (NPs) and its application towards effective dye degradation in aqueous system. The hybrid system integrates the photocatalytic capabilities of TiO₂ with biocompatibility of pectin while PVA provides the structural ability and better hydrogel network. The incorporation of the TiO₂ NPs was also successfully confirmed by a range of tests, including Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Response surface methodology (RSM), (Central Composite Design, CCD) was applied to reach an optimal dye degradation process statistically with four parameters: TiO₂ NPs dosage, degradation time, initial concentration of dye and pH being analyzed. Optimization gave a degradation efficiency of 78.74% for a minimum dosage of 0.754&#xa0;wt% which proved that incorporating TiO₂ NPs clearly improved the degradation efficiency. Scavenger experiment were performed to understand the ROS of the process and found that hydroxyl radicals were primary ROS, All the prepared hydrogel for dye degradation follows pseudo-first&#xa0;order kinetics and the thermodynamic analysis revealed that the process was more favorable with increase in temperature. Positive ΔH˚representing that energy requirement drives the degradation effectively, and positive ΔS˚ values indicated the disorderness of the process. Reusability experiments confirmed that it is possible to re-use the hydrogel without loss of TiO₂ NPs. Life cycle assessment and Techno economic analysis was initiated for the process to understand the scalability, feasibility and environmental impact of the process adopted.</p> Graphical abstract <p></p>
