The invention relates to a waste material recovery device which comprises a material guide barrel. A feeding screw is actually arranged in the material guide barrel, and a threaded tooth is arranged on the outer surface of the screw; a motor is arranged at the left end of the material guide barrel, and the motor is connected to the feeding screw through a rotary shaft; a feeding hopper is arrangedabove the left portion of the material guide barrel; a fuser is arranged around the external end of the middle of the material guide barrel, and a temperature control device is arranged above the fuser; a discharge port is formed in the right end of the material guide barrel, a filter plate is locked in the discharge port, and the left end of the filter plate is fixed to the right side of the feeding screw through a positioning seat; and a supporting rack is arranged below the bottom of the material guide barrel. The waste material recovery device provided by the invention can fuse plastics effectively and comprehensively through the fuser and the temperature control device, and separate the fused plastics in liquid state from deposited impurities at one time; by forming the detachable discharge port, the filter plate can be cleaned periodically, and the blocking phenomenon in the filter device can be solved by means of double functions, so that the efficiency is increased.
