Abstract

Since C&D waste consists of various properties, the importance of eco-friendly treatment through separation and discharge according to the source is increasing. In Korea, C&D waste is called Total construction wastes (TCW), It is classified as construction waste (CW) with an amount of more than 5 tons, and construction site household waste (CHW) with less than 5 tons. Recently, it has been confirmed that most of CHW are simply incinerated or landfilled due to not properly management. However, there is only one case in Korea that classifies CHW, and since it is small compared to CW, there has been no case of research related to construction waste

In this study, the management status of TCW was diagnosed using Seoul as a case, and problems and improvement were reviewed the management of CHW. In the current management system of CHW, it is impossible to identify the amount of waste generated and induce separate discharge, and most of it is mixed and discharged and landfilled. To improve these problems, a separate discharge method for each type of CHW, establishment of discharge reporting system, installation of public sorting centers for each autonomous district, and a total volume system for loading into landfills were proposal. Through this improvement, it will be possible to establish statistics that can identify the generation and treatment amount of CHW, and it will be possible to establish a management plan based on these statistics. In addition, it will be possible to manage and supervise the separate discharge and reduce the amount of mixed CW as the public sorting facility is expanded and the amount of landfill is limited. In addition, by sharing Korea’s construction waste management cases, it can be used in a system that can efficiently manage construction waste in various countries.
