Disclosed is a method of recovering inorganic pigment such as TiO2 from a coating composition that includes liquid, an organic component, and an inorganic component. The coating composition is thermally treated to remove at least a portion of the organic component and yield an inorganic pigment composition having a higher concentration of the inorganic pigment (TiO2) than in the original coating composition.
