Abstract: A system for recycling waste artificial marble using a fluidized bed rapid pyrolyzing technology according to the present invention comprises a storage (10) storing pulverized materials (6a) of waste artificial marble; a pyrolyzing and plasticizing device (20) receiving and heating the pulverized materials (6a) of waste artificial marble stored in the storage (10) so as to generate methyl methacrylate and aluminum oxide by pyrolysis and plasticize the aluminum oxide simultaneously; a fluidized bed pyrolyzer (21) installed inside the pyrolyzing and plasticizing device (20) and mixing the pulverized materials (6a) of waste artificial marble with fluidized sand (240′) so as to make the mixture flow and be pyrolyzed into methyl methacrylate and aluminum oxide; a solid separating means separating solids (251, 252) from gas discharged from the pyrolyzing and plasticizing device (20); a condensing means cooling gas which passes out through the solid separating means so as to collect liquid methyl methacrylate; and a gas recycling means supplying at least part of the gas which passes out through the condensing means again to at least one of the storage (10) and the pyrolyzing and plasticizing device (20). In the present invention, a reactor for pyrolyzing waste artificial marble and a calcining furnace for plasticizing aluminum oxide are integrated to be a fluidized bed pyrolysis reactor installed in the calcining furnace so that the collection of aluminum oxide is facilitated and energy can be saved.
