All over the world pollution is the major problem in Nowadays. Next generation people are must concentrate on environment to lead a life in pollution free world .Dyes are the major polluting agent of water body so, In the present study, CaO photocatalyst was synthesized from waste chicken egg shells by physical method and it was treated with Rhodamine B under sunlight and results shows the optimum dye concentration of Rhodamine B is 10ppm at optimum catalyst 0.5 mg , optimum calcination temperature is 500°C, at 90 minutes at 200 rpm is shows better results.
