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 for fuels. SOLUTION: In a treating method of waste foamed urethane materials, the waste foamed urethane materials are thermally compressed so as to soften and simultaneously shrink the waste foamed urethane materials and next cooled and solidified. And, in a method for feeding the waste foamed urethane materials to a furnace, the waste foamed urethane materials are thermally compressed so as to soften and simultaneously shrink the waste foamed urethane materials and next cooled and solidified. This solidified matter is crushed and granulated so as to blow this granulated matter in a furnace. At the thermally compressing of the waste foamed urethane materials, the preliminary mixing of a thermoplastic resin with the waste foamed urethane materials is preferable.
