In Japan, There has been a strong demand that building construction sites should reduce construction byproducts to decrease the burden to the environment. Recently, we have administered an investigation to grasp the amount of construction byproducts at construction sites, with which we examined various methods to diminish construction byproducts and analyzed their efficiency. For this study we have continuously investigated the kinds and the amount of construction byproducts in the construction process. As the result, various factors at the construction sites revealed the effectiveness of sorting out mixed byproducts of the construction byproducts. We suspect that controlling the amount of byproducts at construction sites would contribute to reducing the burden on nearby environments.
