Abstract

The vacuum insulation panel (VIP) used to insulate the inside of refrigerators is made of glass fiber and requires detecting and separating before physical shredding in recycling stage. In this study, we developed pilot facilities consisting of cutting, detaching the outer plate of the refrigerator, and separating the VIP to secure core materials for recycling and/or reuse. For this purpose, we estimated operational capacity using ten refrigerator samples by measuring the takt time in both the unit and continuous processes. According to the results, the mean takt time in the unit process was 203.7 s for cutting, 226.0 s for detaching, and 54.2 s for separating, respectively. The continuous process (integrated cutting and detaching) required 429.7 s per unit. These findings are significant, as this is the first practical study with pilot facilities in South Korea on embedded VIPs in end-of-life refrigerators.

韩国废弃冰箱真空隔热板回收系统的开发：切割、分离、分离技术

用于冰箱内部绝缘的真空隔热板（VIP）由玻璃纤维制成，在回收阶段需要检测和分离才能进行物理撕碎。在这项研究中，我们开发了试点设施，包括切割，分离冰箱的外板，分离VIP，以确保核心材料的回收和/或再利用。为此，我们通过测量单元和连续过程中的节拍时间来估计使用十个冰箱样品的操作能力。结果表明，该工艺的平均切割时间为203.7 s，分离时间为226.0 s，分离时间为54.2 s。连续工艺（综合切割和分离）每台需要429.7秒。这些发现意义重大，因为这是韩国首次在废弃冰箱中嵌入vip的试点设施进行实际研究。

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
