Abstract: It is common that building finishing materials that have durability and design properties are essential for buildings. In recent, maintenance and repair-work except the new construction of the building increases, and it is expected that the amount used of the building finishing materials increase in future. However, it remains to be elucidated the recycling method for the building finishing wastes especially the PVC building wastes that have the majority on the building finishing materials.The main reason of low recycling rate is that the PVC building wastes are usually discharged as mixed waste with impurities.Therefore, we aim to develop the recycling method for PVC building wastes. Here we found the new method that is able to separate recycling PVC powder from PVC building wastes.Specifically, it targeted tile carpets, wallpapers and PVC waterproof sheet. Moreover, here we made the recycling sheets by the PVC recycling powder, and evaluated the quality of the recycling sheets. Finally, we evaluated that the effect of the new recycling method can reduce damage of environment and energy use.These observations indicate that the new recycling method is able to reduce PVC building wastes and intend for practical use. These results are not only reducing the amount of the building wastes, but also contributing for a sustainable society.
