[0002] Medical waste is infectious, toxic and other harmful waste generated by medical institutions in medical, preventive and health care activities. Medical waste contains a large number of pathogenic microorganisms and harmful chemicals, which will pose a great threat to human health. Therefore, my country stipulates that waste must be strictly handled. Common treatment methods are incineration or pyrolysis.

[0003] In order to avoid the spread of pathogenic microorganisms and harmful chemicals in the process of medical waste treatment, unpacking is not allowed before incineration or pyrolysis. Usually, the whole package of waste is incinerated or pyrolyzed. However, in the prior art, there is no classified collection of metal utensils in medical waste. Therefore, the metal utensils mixed in medical waste not only increase the difficulty of incineration and pyrolysis, but also cause a certain waste of resources; and the waste residue after incineration and pyrolysis contains a large amount of metal slag, which also affects the treatment and utilization of the waste residue.
