To provide a recovery method capable of recovering good quality steel materials and aluminum materials from used beverage cans and at the same time, recovering the paints for can bodies, coating materials, and mixed inorganic, substances.

When the used beverage cans are heated in a non-oxidizing atmosphere to separately recover good quality steel and aluminum, the paints and coating materials coating the outer and inner surfaces of the can bodies are gasified or decomposed to form gases. These gases are cooled to be liquefied, and then the resultant oily matter is separated and collected.
