General Description of the Research Project In order to actively promote the recycling of construction and demolition waste (CDW) in Vietnam, this study aims to 1) establish guidelines necessary for the environmentally sound CDW management and quality standards for recycled materials produced from CDW; 2) develop new technologies utilizing recycled materials produced from CDW; and 3) propose strategic business models designed to promote the CDW recycling in Vietnam and examine their effectiveness and feasibility through on-site pilot projects. The new technologies utilizing recycled materials consist of two components: one is a water treatment technology for heavy metal-contaminated/oil-polluted water, and the other is a permeable road pavement technology with the high water-retentive subbase system. The effectiveness of these technologies will be validated based on the results from field experiments. The final goal of this study is to contribute to the achievement of a CDW recycling rate of 60%, which meets the Vietnam national strategy for management of solid waste up to the year 2025, through the application of developed technologies and business models to practical recycling businesses.
