<p>PURPOSE:To obtain a method of disposal of waste, which allows to execute the land-reclamation and reuse effectively, by a method wherein the waste is heated up to a predetermined temperature, and stirred and further, after cooling and solidifying, ground. CONSTITUTION:In order to reduce the bulk of waste magnetic tape or sheet, the waste tape or sheet is heated to 220-300 deg.C so as to make it brittle by denaturizing thermosetting resin and also the base material is melted or made brittle in order to grind it to the particle size of 10 mesh or less. At the disposal of the waste magnetic tape or sheet, less than 20wt.% of modifier is added to the waste magnetic tape or sheet in advance and, after that, the tape or sheet is heated to 220-300 deg.C and stirred of a reforming member of less than 20wt.% is added to the waste magnetic tape or sheet while heating to 220-300 deg.C and stirring. After cooling and solidifying, the resultant waste tape or sheet is ground to the particle size of 10 mesh or less.</p> |
