Abstract Photocatalysis is proposed as an environmentally friendly technology that exploits solar light for environmental purification. While its effect on treated effluent quality indeed positive, studies overall profitability generally disregard the fact photocatalytic materials may themselves generate pollution in their production, use, and end‐of‐life phases. This work addresses two distinct methods titanium dioxide (TiO 2 ) coatings preparation, is, chemical –sol–gel, associated with spray coating– electrochemical –anodic oxidation, which generates oxide directly from a substrate. Oxides are tested decomposition of tetracycline, antibiotic commonly found water. Both distilled tap water used matrices. Coatings multiple times to simulate real operating conditions, until activity compromised. Life Cycle Assessment (LCA) then quantify compare potential impacts different TiO production strategies. Eventually, assessment completed by considering full photocatalyst regeneration: while Sol–Gel this only implies cleaning re‐deposition, anodizing required detachment, subsequent re‐anodization. The process removal re‐anodizing, although invasive consuming, repeated 20 without significant loss efficiency, indicating robustness suitability transfer.
