Abstract
Provided are a light-emitting gas recovery method and a recovery apparatus that allow light-emitting gas to be recover efficiently. A light-emitting gas recovery method includes: a step (a) of preparing a lamp to be discarded including a tube body filled with the light-emitting gas; a step (b) of placing the lamp in an internal space of a chamber; a step (c) of reducing an air pressure in the internal space of the chamber; a step (d) of applying energy to a part of the tube body to allow an internal space of the tube body and the internal space of the chamber to communicate with each other without entirely breaking the tube body, and releasing the light-emitting gas from the tube body; and a step (e) of discharging a first gas present in the internal space of the chamber toward a recovery mechanism after the step (d).
