Description

<p>In Vietnam, the amount of construction and demolition waste (CDW) has been increasing with rapid economic growth. A recycle and appropriate treatment of CDW seems to be insufficient because almost of CDW is dumped in a landfill or another land directly. This study tried to reveal the current situation of CDW generation and treatment in Hanoi city. We conducted the questionnaire survey to several constructors who contact demolition work and revealed almost of constructors did not recognize the regal framework about obligation of CDW sorting and appropriate recycling. In addition, the field survey at several demolition site was carried out. It was indicated that the combination of manual sorting work and machine demolition work was used generally. Moreover, we revealed that not only metallic waste such as reinforcing steel but also mixed waste such as residue of concrete and brick were traded for valuable materials. We concluded that the clarification of CDW flow and the development of several guidelines of CDW sorting methods are needed for accelerating CDW recycling in Vietnam.</p>
