Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treating waste, sludge, scale, coke powder, coal fine powder or ore powder containing iron produced in an iron works for obtaining a recycled raw material for iron-making. SOLUTION: In a method for using the waste containing iron as the iron- making raw material to pre-treated two or more kinds among the dust, the sludge, the scale, the coke powder, the coal fine powder and the ore powder produced in the iron works, waste toner is added at 0.1-8.0 wt.%, pulverized and kneaded at a temperature of 40-80 deg.C to make pseudo-granulation of the mixture.
