废旧衣物回收资源化利用典型模式及其环境绩效分析

Typical model for recycling of used clothes and analysis of environmental impact

为推动国内废旧衣物回收资源化利用,量化其环境绩效,在介绍分析一种由品牌企业牵头引导的废旧衣物回收资源化利用典型模式基础上,以全生命周期评价方法为基础,通过划定系统边界构建出其环境绩效的计算方法,并且通过数据采集和量化分析,计算出了该典型模式的环境绩效。研究表明,废旧衣物回收资源化具有明显的环境绩效,品牌企业对废旧衣物回收资源化利用具有积极的带动和促进作用、在延长纤维资源生命周期的同时,还可带动工业产品绿色设计工作的开展。本文研究中的计算方法不仅可为废旧衣物回收资源化利用过程中的环境绩效提供指导,同时也可为纤维资源综合利用过程中的多生命周期产品的环境行为评价提供参考。

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.
