Abstract:

In order to promote the recycling of domestic used clothing and quantify its environmental impact, this study introduces and analyzes a typical model for used clothing recycling and resource reutilization led by brand companies, employing the life cycle assessment method. By delineating the system boundary, a calculation method for the environmental impact was constructed, and the environmental impact was calculated through data collection and quantitative analysis. Studies have shown that the recycling of used clothing has obvious impact on environment. Brand companies have an active role in driving and promoting the recycling and utilization of waste clothing. While extending the life cycle of fiber resources, it can also promote the development of green design of industrial products. In addition, the calculation method proposed in this study can not only provide guidance for evaluating the environmental impact of the recycling process of used clothing, but also provide a reference for the environmental behavior evaluation of multi-life cycle products in the process of comprehensive utilization of fiber resources.

Key words: used clothing recycling, resource utilization, recycling mode, environmental impact, brand company
