**5. Conclusion**

Ginger lily fibers are a new sustainable resource for new product development. Its surface can be coated with a thin film of TiO2 by reactive magnetron sputtering whose topography can be tailored depending on the power used and the percentage of oxygen in the chamber. Regarding the structure, the application of 500 W power allows obtaining a TiO2 film with an amorphous structure, while the samples with twice the power showed polycrystalline structures. Anatase is the dominant phase in the films deposited at 1000 W. XPS and FTIR analyses revealed that ginger lily fibers can serve as a new sustainable resource for developing novel products, and the topography of the TiO2-coated fibers can be tailored by adjusting the power and oxygen percentage during reactive magnetron sputtering.
