METHOD AND APPARATUS FOR TREATING DISCARDED TONER CARTRIDGE, SOLID FUEL OBTAINED BY USING DISCARDED TONER, AND REGENERATED PLASTIC MATERIAL

摘要

PPROBLEM TO BE SOLVED: To provide a method of treating discarded toner cartridges by which toners remaining in discarded toner cartridges of various shapes are easily recovered without causing environmental pollution, whereby the following crushing and separation of the discarded cartridges are facilitated, and by which recovered discarded toners are taken out as cakes of a uniform shape free from burrs and can be utilized in other use. PSOLUTION: The method for treating discarded toner cartridges includes the steps of sucking and recovering residual toners from discarded toner cartridges, compression-molding and melt-solidifying the recovered residual toners, crushing the discarded cartridges from which the residual toners have been recovered, and separating the crushed material into at least metals and nonmetals.
