In the present work is presented a reusable support material based on waste, photo catalytically functionalized with zinc oxide film. The obtained immobilized catalyst was structurally characterized using SEM equipment and successfully used in the photocatalytic degradation of an organic compound present in aqueous solutions with yields of over 97%. The proposed catalytic material is important in the context of the circular economy and sustainable development by restoration in the economic circuit of some waste into functional products with wastewater treatment applications, thus contributing to the preservation of water resources and to the smart waste management.
