Summary:PROBLEM TO BE SOLVED: To provide a waste disintegrating treatment method capable of cutting a copper wire to be cut without fixing the same and recovering copper from the waste certainly and easily by low energy. SOLUTION: In a method for the disintegrating treatment of waste containing a copper part comprising tough pitch copper, tough pitch copper in waste is subjected to embrittlement treatment to facilitate the disintegration treatment of waste. The embrittlement treatment is performed in a high temp. environment in the presence of hydrogen and fluorine and, concretely, a hydrocarbon bond- containing compd. and a fluorine atom-containing compd. are allowed to be present in the waste and this waste is heated at 500-1050 deg.C in an oxygen-free or low oxygen atmosphere to embrittle tough pitch copper in the waste to facilitate the disintegration of the waste. That is, the waste is a waste motor and a copper wire can be separated by cutting an embrittled copper wire.
