    • PROBLEM TO BE SOLVED: To provide a method for transporting waste by an air capsule capable of transporting the air capsule efficiently, economically, and safely than conventionally in an air capsule transporting system adapted to geological disposal of radioactive waste. SOLUTION: Upon transporting the capsule downward to under the ground by a pressure difference between the front and rear of the capsule in an air transport conduit 1 disposed from above the ground to under the ground, a capsule discharge conduit 11 connected to an upper part of the air transport conduit 1 and a capsule moving device 12 provided to the capsule discharge conduit 11 are used. The capsule 2 is disposed at an upper part of the capsule discharge conduit 11, and is moved downward and accelerated to a prescribed speed by the capsule moving device 12, while opening an opening and closing valve 16 at the upper part of the capsule discharge conduit 11 and introducing air into a space between a tube end of the capsule discharge conduit 11 and the capsule 2. After the moving down speed is maintained at a constant speed, the opening and closing valve 16 is closed, and the capsule 2 is released from the capsule moving device 12 to fall freely.
