Abstract

Electronic waste (e-waste) is a rapidly growing problem worldwide due to the increasing consumption of electronic devices and the short lifespan of these products. E-waste recycling and utilization have emerged as potential solutions to this problem, aiming to recover valuable materials and minimize environmental impact. This review article provides an overview of the current e-waste recycling and utilization technologies, including mechanical recycling, pyrolysis and gasification, hydrometallurgical and bio-metallurgical processing, and emerging technologies. The challenges and limitations of e-waste recycling and utilization are also discussed, including technical, economic, social, and environmental aspects. Additionally, we include the case studies and success stories worldwide, highlighting examples of successful e-waste recycling, utilization and lessons learned. Finally, we conclude by summarizing the future perspectives and opportunities of e-waste management are also explained.

电子废物的回收和利用：当前技术回顾与未来展望

由于电子设备的消耗量不断增加，而这些产品的寿命又很短，因此电子废物（E-waste）是一个在全球范围内迅速增长的问题。电子废弃物的回收和利用已成为解决这一问题的潜在方案，其目的是回收有价值的材料并最大限度地减少对环境的影响。本综述文章概述了当前的电子废物回收和利用技术，包括机械回收、热解和气化、湿法冶金和生物冶金处理以及新兴技术。还讨论了电子废物回收和利用所面临的挑战和局限性，包括技术、经济、社会和环境方面。此外，我们还纳入了全球范围内的案例研究和成功故事，重点介绍了电子废物回收、利用的成功案例和经验教训。最后，我们总结了电子废物管理的未来前景和机遇。
