Many aspects of modern life of our civilization are associated with using electrical and electronic devices (EEE). Ever-increasing demand for high-performance EEE and accelerated technological development make the replacement of EEE become frequent. This leads to the generation of a tremendous amount of electronic waste (E-waste). Challenges of the management of E-waste have recently arisen out of a dearth of proper technologies to treat E-waste. Pyrolysis process can thermochemically treat waste materials that have a complicated nature and inhomogeneity. This article gives a systematic review as an effort to tackle the challenges in the context of achievements in pyrolysis process in E-waste management sector. Pyrolysis mechanism and types of pyrolysis processes and pyrolysis reactors are first discussed. Various pyrolysis technologies applied to the E-waste treatment are then summarized and compared to each other. Points to be considered for further research and pending challenges of E-waste pyrolysis are also discussed. The pyrolysis treatment of E-waste is not yet fully industrialized mostly because of high costs. However, there should be much room for further developing the E-waste pyrolysis; hence, its industrialization and commercialization is just a matter of time.

电子废物管理领域热解工艺的成就

我们文明现代生活的许多方面都与使用电气和电子设备 (EEE) 相关。对高性能电子电气设备需求的不断增长以及技术发展的加速使得电子电气设备的更新换代变得频繁。这导致产生大量电子废物(E-waste)。由于缺乏适当的电子废物处理技术,最近出现了电子废物管理的挑战。热解工艺可以对性质复杂、不均匀的废弃物进行热化学处理。本文对电子废物管理领域热解过程所取得的成就进行了系统回顾,以应对挑战。首先讨论了热解机理以及热解过程和热解反应器的类型。然后总结并比较了应用于电子废物处理的各种热解技术。还讨论了进一步研究需要考虑的要点以及电子废物热解面临的挑战。电子垃圾的热解处理尚未完全工业化,主要原因是成本较高。然而,电子垃圾热解技术还有很大的发展空间;因此,其产业化和商业化只是时间问题。
