End-of-life (EOL) ships contribute significantly to the flow of recycled industrial Fe and non-Fe metal materials in resource-poor developing countries. The ship scrapping (breaking) and recycling industry (SBRI) recycles 90-95% of the total weight of EOL ships and is currently concentrated in Bangladesh, India, Pakistan, Turkey, and China, due to the high demand for recyclable and reusable materials there, an abundance of low-cost labor, and lenient environmental regulations. However, the SBRI has long been criticized for non-compliance with standards relating to occupational health, labor safety, and to the management of hazardous materials. Among the different EOL recycling options, Bangladesh, India, and Pakistan use open beaching, a technique that exposes all spheres of the environment to the release of hazardous materials from EOL ships. This article summarizes the current state of knowledge on the environmental exposure of hazardous materials from SBRI, to judge the risks associated with the dismantling of EOL ships on open beaches. Our work includes an overview of the industry and its recent growth, compares available ship-breaking methods, provides an inventory of hazardous releases from EOL ships, and reviews their movement into different spheres of the environment. The economic dynamics behind open beaching, and apportionment of responsibility for hazards related to it, are discussed, in order to generate policy and legal recommendations to mitigate the environmental harm stemming from this industry.
在资源匮乏的发展中国家,报废船舶(end-of-life (EOL) ships) 是再生工业铁和非铁金属材料流动的主要贡献者。船舶拆解和回收工业(Ship Scrapping (breaking) and Recycling Industry (SBRI)) 回收了报废船舶总重量的 90-95%,目前主要集中在孟加拉国、印度、巴基斯坦、土耳其和中国,因为这些国家对可回收和再利用材料的需求很高,劳动力成本低廉,环境法规宽松。然而,长期以来,SBRI 一直因其不符合与职业健康、劳工安全和危险材料管理有关的标准而受到批评。在不同的报废船舶回收选择中,孟加拉国、印度和巴基斯坦使用开放式海滩拆解技术,这种技术将环境的各个领域暴露于报废船舶释放的危险材料中。本文总结了目前关于 SBRI 中危险材料的环境暴露的知识状况,以评估在开放海滩上拆解报废船舶所带来的风险。我们的工作包括概述该行业及其最近的增长情况,比较现有的船舶拆解方法,列出报废船舶释放的危险物质清单,并审查它们进入环境不同领域的情况。还讨论了开放式海滩背后的经济动态以及与之相关的危险责任分配,以制定政策和法律建议,减轻该行业造成的环境危害。
