Abstract

PURPOSE: To convert leather sludge into stable cake in the melt disposal of the leather sludge, by converting the leather sludge into dried cake, incineration remnants or distillation remnants, adding solid waste containing a large amount of SiO2 to the cake or remnants, and then melting the mixture.
CONSTITUTION: Leather sludge generated in a leather-making step is converted into dried cake, incineration remnants or distillation remnants. Solid waste containing a large amount of SiO2, e.g. dried cake of municipal sewage sludge or the like, is then added to the cake or remnants in such an amount that cake to be obtained after melting will have a basicity of about 1.0W2.0. Thereafter, the mixture is melted in a furnace 8 to produce stabilized cake. In the furnace 8, the leather sludge is melted by an arc from a graphite electrode 1, and the molten slag 6 is discharged through a discharge opening 7. The molten slag 6 is then carried to a conveyer-type slag-caking device.
