    予稿集名 : Construction and demolition waste (CDW) has become a major issue that Southeast Asian (SEA) countries must now face up to. This study conducts a review of a wide array of documents related to CDW management in the SEA region, including journal papers, legal documents and statistics as well as national and international reports. CDW definition in the legal documents, current state of CDW generation, CDW composition and CDW flow as well as institutional arrangements for CDW management are assessed. The review results indicate the inadequacy of current CDW management in almost all of the SEA nations with a dearth of proper database on the amount of CDW generated and proportions of CDW components. Additionally, insufficient designated legal documents and unclear responsibility assignment have also been witnessed in these countries’ systems of CDW management. The findings of this study suggest that greater effort must be placed by the SEA countries’ governments to develop a holistic system of CDW management stressed on CDW reusing and recycling.

    Appropriate Management of Construction and Demolition Waste to Prevent Waterway Blockage
    発表者 : Hoang N.(HOANG Ngoc Han), Yamada M.(山田正人), Ishigaki T.(石垣智基)
    学会等名称 : 4th International Forum on Sustainable in Asia (2019)
    予稿集名 : Construction and Demolition Waste (CDW) is one of the emerging waste streams in Asian countries. Not only causing health related problem, CDW is also responsible for a wide array of environmental issues, including growing flood risks in urban areas through blocking drainage channels and waterways. A recent study in Thailand has discovered that CDW (wood and timber waste) accounted for approximately 45% of total solid waste dumped into Lad Prao canal, Bangkok. To respond to this situation, it is of great importance that CDW is well managed, especially through CDW recycling. In Vietnam, approximately 1.9 million tons of CDW was generated in 2010. Whilst there is so far no official data on the amount of CDW in waterways in Vietnam, it is reported that the majority of CDW is being discarded at the dumping sites or illegally dumped into lakes, rivers and other areas. Given the continuous development of the construction industry with the expected growth rate of 9.2% in 2018, it is very likely that the quantity of generated CDW and the associated risk in increasing urban flooding will significantly rise unless more attention is paid to manage and recycle this type of waste. The Vietnamese government, therefore, has set the national target of 90% of urban CDW collected and treated whilst 60% reused and recycled by 2025., 25-25
