Abstract

The South Korean government has implemented an acceptance system to promote the high-quality recycling of waste. Industrial waste generators must provide “hazardous characteristics data” to recycling operators. Nonetheless, ~80% of industrial safety accidents in South Korea occur during recycling, most involving fire or explosions. Moreover, a gap in safety management exists during ‘Circular Resource’ acceptance if the target substance is not regarded as waste. In this study collected data on hazardous waste characteristics. From 62 waste generators, 72 waste samples were collected, accounting for most of the resources accepted for recycling, including waste synthetic polymers, slag, dust, waste sand, and waste foundry sand. Then, the hazardous characteristics, as stated in the Ministry of Environment notifications, were assessed. Leaching toxicity was detected in one slag sample and six dust samples. The Cd, Cu, As, Pb, Zn, Ni, Hg, F, and CN levels dissatisfied the Soil Contamination Warning Standard in 31 samples. Explosivity was not detected in any sample, whereas flammability was detected in one waste synthetic polymer sample. The results revealed 15 cases of potential flammability. Flammability is legally defined as below the criteria if the combustion speed criterion is not met. However, in the case of flame ignition, which could cause large fires and safety accidents, the relevant notification should be revised. In this study, we aimed to improve the gap between the hazardous waste management systems and industrial fields through actual measurements of hazardous characteristics. By doing so, we seek to contribute to the prevention of environmental and safety accidents. By continuously accumulating data and utilizing actual measurements, we aim to revise and enhance relevant regulations, ultimately improving the hazardous characteristics of waste management systems.

通过危险特性分析加强韩国工业废物的可持续回收系统
韩国政府实施了一项验收制度,以促进废物的高质量回收利用。工业废物产生者必须向回收经营者提供 "危险特性数据"。然而,韩国约 80% 的工业安全事故发生在回收过程中,其中大部分涉及火灾或爆炸。此外,如果目标物质不被视为废物,那么在 "循环资源 "接收过程中就会出现安全管理漏洞。本研究收集了有关危险废物特征的数据。从 62 个废物产生者中收集了 72 个废物样本,其中包括废合成聚合物、炉渣、粉尘、废砂和废铸造砂等大部分可接受循环利用的资源。然后,对环境部通知中规定的危险特性进行了评估。在一个炉渣样本和六个粉尘样本中检测到了浸出毒性。在 31 个样本中,镉、铜、砷、铅、锌、镍、汞、萤石和氯化萘的含量不符合土壤污染警告标准。没有在任何样本中检测到爆炸性,但在一个废弃合成聚合物样本中检测到可燃性。结果显示有 15 个样品存在潜在的易燃性。如果不符合燃烧速度标准,可燃性在法律上被定义为低于标准。但是,在火焰点燃的情况下,可能会引发大火和安全事故,因此应修订相关通知。在这项研究中,我们旨在通过对危险特性的实际测量,改善危险废物管理系统与工业领域之间的差距。通过这样做,我们力求为预防环境和安全事故做出贡献。通过不断积累数据和利用实际测量结果,我们旨在修订和完善相关法规,最终改善废物管理系统的危险特性。
