METHOD AND SYSTEM FOR RECYCLING INCINERATION RESIDUE

PROBLEM TO BE SOLVED: To provide a technology for efficiently and economically removing salt components contained in incineration residues in recycling the incineration residues already landfilled and incineration residues which are presently being generated. SOLUTION: The method and system for recycling the incineration residues comprise the steps for: separating the incineration residues by a predetermined size; using the incineration residues of larger sizes than the predetermined size as it is or after desalination with water treatment as a cement raw material or a material of construction; mixing the incineration residues of smaller sizes than the predetermined size with organic contents and storing the same in an outdoor disposal site; and using the incineration residues the salt concentration of which is reduced by natural desalination as the cement raw material or the material of construction. By adopting the system, the desalination of the incineration residues can be carried out at a low cost by reducing new equipment investment and consumable costs, which promotes economical recycling of the incineration residues.
