Tóm tắt
The rapid growth of vehicle ownership in Vietnam has generated approximately 400,000 metric tons of waste tires annually, most of which are still disposed of through landfilling or incineration, exerting substantial environmental pressure. Within the sustainable development context, recycling waste tires into construction materials represents a promising resource recovery pathway. This study assesses the feasibility of incorporating recycled rubber into construction materials through a systematic literature review and field surveys at 20 tire facilities in Hanoi. Results indicate that replacing 5%-20% of concrete aggregate with recycled rubber improves impact absorption, acoustic insulation, and flexibility, though compressive strength tends to decline. The current collection and processing system remains fragmented, dominated by small-scale operators, with no established value chain linking waste tire flows to the construction sector. Technical standards and targeted policy instruments are needed to enable large-scale adoption and advance circular economy practices in Vietnam's waste management and construction sectors.
