AN INVESTIGATION OF THE GENERATION AND MANAGEMENT OF CONSTRUCTION AND DEMOLITION WASTE IN VIETNAM

Abstract

As a developing country in the context of globalization, Vietnam is experiencing a boom in its economy, characterized by a rapid rate of urbanization nationwide. Together with its benefits, this process also puts pressure on the environment, among which the increasing generation of construction and demolition waste (CDW) is an urgent issue. In this study, the authors conducted an in-depth investigation of various aspects in the generation and management of CDW in Vietnam. Firstly, part of the overall picture of CDW management in Vietnam was revealed in detail from the perspective of demolition contractors, one of the important stakeholders in the field. Their insights provide valuable information on current situation, practice, and attitude towards CDW recycling. Secondly, this paper reports the generation rate of different categories of materials from demolition sites of building structures in Hanoi, Vietnam, with the main focus on crushed concrete and crushed brick (CC–CB) and steel as they make up the majority of the generated waste. In order to achieve two mentioned goals, close contact was constantly kept with a key collaborator – a renowned demolition contractor in Hanoi throughout the investigation. The collaborator provided proper introduction to enable interviews with various other contractors, together with information of buildings being dismantled.
