Abstract

One of the alternatives for reducing greenhouse gas emissions is the ongoing effort to lighten the weight of vehicles. Therefore, the proportion of end-of-life vehicles (ELV) plastic (ELVP) is expected to increase. In this study, material flow analysis (MFA) of ELVs and the first ELVP–MFA were conducted in the Republic of Korea. The amount of ELVP dismantled from ELVs was 22,600 tons per year. Of these, 22,000 tons were sent to recycling facilities. The actual recycling rate was only 51.7 %, and the practical recycling rate was lower. Large amounts of inorganic matter and plastic additives, including those from ELVP, were detected in the ELVs. In other words, metal resources are lost, and hazardous substances are estimated to be released into the environment during the ELV treatment process. In this study, problems at each life cycle stage were identified, and improvements were proposed for the management of ELVs, including ELVP.

韩国报废车辆塑料管理：物料流分析和有害物质分析

减少温室气体排放的替代方案之一是不断努力减轻车辆的重量。因此，报废车辆（ELV）塑料（ELVP）的比例预计会增加。在本研究中，进行了elv的物质流分析（MFA），并在韩国进行了首次ELVP-MFA。每年从轻型运载工具中拆卸的轻型运载工具的数量为22,600吨。其中，2.2万吨被送往回收设施。实际回收率仅为51.7%，实际回收率更低。在elv中检测到大量无机物和塑料添加剂，包括来自ELVP的添加剂。换句话说，在ELV处理过程中，金属资源损失，有害物质估计释放到环境中。在本研究中，确定了每个生命周期阶段的问题，并提出了对elv管理的改进措施，包括ELVP。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
