SHRINK TREATING METHOD OF WASTE FOAMED URETHANE MATERIAL AND METHOD FOR FEEDING WASTE FOAMED URETHANE MATERIAL TO FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a treating method for turning waste foamed urethane materials in a reusable state as resources and, at the same time, a feeding method for the waste foamed urethane materials to a furnace as raw materials or the substitute materials for fuels. SOLUTION: In a treating method for turning in a reusable state, waste foamed urethane materials are thermally softened and kneaded in the state being compressed so as to be shrunk and next cooled and solidified. Or, in a method for feeding to a furnace such as a blast furnace or the like, the waste foamed urethane materials are thermally softened and kneaded in the state being compressed so as to be shrunk in order to granulate this shrunken kneaded matter for blowing the granulated matter in the furnace through an airborn transportation. At the thermally softening of the waste foamed urethane materials, the preliminary mixing of a thermoplastic resin with the waste foamed urethane materials is preferable.
