Host: Japan Society of Material Cycles and Waste Management
Recently environmental pollution and resource depletion have been rapidly progressing all around the world. Construction Industries are becoming the cause of improvement of environmental loads as they discharge large amount of construction and demolition waste (C&D waste) and consume heavy resource compared with other industries. Since the mid-1990s, C&D waste materials have been rapidly increasing due to the revitalization of reconstruction, redevelopment and development of new urbanization in Korea. Thus, various studies have attempted to establish the proper C&D waste management plan. C&D waste materials are typically separated by their characteristics and recycled as a priority treatment method in accordance with government treatment guidelines. According to the Korea Ministry of Environment (Korea MOE) statistics, recycling rate of construction was 97.5% in 2013. However, the recycling rate presented by statistics of the Korea MOE is calculated by the amount of waste incoming to a recycling facility, not actual recycling rate after the recycling processes. In order to understand the actual recycling rate of C&D waste at the national level, it is important to examine the processes of C&D waste recycling facilities and determine mass flow through material flow analysis (MFA).
