Recycling of construction materials used for house or buildings is typically difficult because it is not easy to disassemble them into each material. In particular, urethane insulation has been used in the building and construction industries and it is very difficult to separate from other materials. For example, inside of roof materials, door panel and wall panel, which consist of aluminum skin-plate, are filled in with urethane like composite materials.
In this study, crash of urethane from above mentioned materials was studied using Cross Flow Shredder, which is chain typed shredder. As a result, urethane and other materials were separated each other after grinding and we could show that Cross Flow Shredder is effective for separation of hard-disassembled construction materials into each material.
