Effective water management remains a critical priority for the energy industry, particularly in the  Sustainability and environmental management. The petroleum refining industry generates significant quantities of Titanium dioxide (TiO₂) waste from Claus catalytic processes, posing environmental and economic challenges in waste management. In alignment with sustainable water management and resource efficiency, this study introduces an innovative approach for recycling industrial TiO₂ waste by transforming it into an advanced hybrid nanophotocatalyst. The engineered photocatalyst is functionalized through a straightforward, one-pot synthesis process in which TiO₂ was hybridized with an organic polymer incorporating metal-free porphyrin as active light-harvesting centers and cyanuric chloride as linking ligands, enabling efficient photocatalytic reduction of hexavalent chromium (Cr(VI)) from contaminated wastewater under visible light irradiation.  The synthesized photocatalyst was comprehensively characterized, including textural properties (N₂ adsorption–desorption isotherms), structural features (XRD and FTIR analyses), chemical composition (EDX and XPS spectroscopy), morphological characteristics (SEM and TEM imaging), optical behavior (UV-Vis diffuse reflectance spectroscopy and photoluminescence spectroscopy), and electrochemical performance (electrochemical impedance spectroscopy (EIS), transient photocurrent response, and flat band potential measurements). The hybrid photocatalyst exhibited excellent performance in the photocatalytic reduction of hexavalent chromium (Cr(VI)), achieving a reduction efficiency exceeding 99% under visible light irradiation. The synthesized photocatalyst maintained stable activity and structural integrity over five consecutive reuse cycles. Hybrid Nano-Photocatalyst, visible-light-responsive system derived from industrial TiO₂ waste, offers a sustainable and cost-effective alternative to conventional photocatalysts. To evaluate the trade-offs between the synthesized photocatalyst's environmental benefits and potential drawbacks, a comprehensive life cycle assessment (LCA) was conducted per ISO 14040/14044 using SimaPro and the Ecoinvent database. The life cycle assessment revealed the substantial impacts on marine and freshwater ecotoxicity alongside human toxicity for  the removal of 1 kg chromium using as-synthesized photocatalyst. This assessment underscores the value of LCA as a decision-support tool to guide the development of more sustainable photocatalytic systems by revealing hidden environmental implications often overlooked in performance-based evaluations.
