To provide a waste disposal system using a fluidized bed furnace capable of stably thermally reacting wastes in the fluidized bed furnace without requiring crashing as pre-treatment of the wastes supplied to the fluidized bed furnace.

This waste disposal system comprises the fluidized bed furnace 10 and a supply system supplying the wastes to the fluidized bed furnace. The supply system comprises a waste uniformly supplying chamber 12 connected to the fluidized bed furnace to supply the wastes to the fluidized bed furnace and a waste supply passage 14 connected to the waste uniformly supplying chamber, shielding the waste uniformly supplying chamber from the outside air, and supplying the wastes into the waste uniformly supplying chamber. The waste uniformly supplying chamber 12 is so formed that the received wastes are gradually discharged to the fluidized bed furnace 10 so that the supply of the received wastes into the fluidized bed furnace 10 can be uniformized.
