This chapter discusses the utilization of eggshell wasteEggshell waste for developing composite materials aimed at sustainable water purificationWater purification. The main focus is on the removal of methylene blue (MB), a synthetic dye commonly found in wastewater from the textile industry. Eggshells, as a calcium-rich natural material, are combined with titanium dioxideTitanium dioxide (TiO₂) (TiO₂) to create a composite that facilitates both adsorption and photocatalytic degradation processes. This chapter outlines the synthesis method, characterization techniques, and photocatalytic performance testing of the composite on MB-contaminated samples.
