A method for processing waste solution in the plate-making process of a photosensitive planographic printing plate, with which the maintenance performance of the equipment is excellent, is provided. A method for processing waste solution in the plate-making process, in which the waste solution in the plate-making process, which is discharged when the plate-making process of a photosensitive planographic printing plate is carried out using a developer for a photosensitive planographic printing plate, said developer being characterized by containing at least one sugar selected from non-reducing sugars and at least one base without containing a silicate and by having a pH within the range of from 9.0 to 13.5, is evaporated and concentrated by an evaporative concentration apparatus, thereby being separated into water vapor and a dissolved component, wherein, the waste solution in the plate-making process is heated by a heating means in an evaporation container that is provided with base resistance, and the water vapor separated from the waste solution in the plate-making process is taken out from the evaporation container and condensed in a cooling means, thereby being turned into reclaimed water. |
