“…In the plasma melting method (Jarosz et al, 2011;, SPCBs are treated using a high-energy plasma arc, in which the components of SPCBs are melted through the high temperature of the plasma arc and are then decomposed into gas, glass and different metals via the respective discharge passage. Since the SPCBs are treated under a high-energy and fully closed condition, the degradation of substances in the SPCBs is thus relative completion.…”

The amount of spent electronic and electrical solid wastes (i.e. e-wastes) has increased to a new level with the rapid development of electronic and electrical industries. Management of e-wastes challenges the administrators and researchers. As a major component of the e-waste stream, pollution caused by the spent printed circuit boards has captured increasing attention. Various innovative methods have recently been developed to dispose and reuse these municipal spent printed circuit boards. In this mini-review article, the disposal approaches for spent printed circuit boards are highlighted. The present state and future perspective are also discussed. We hope that this mini-review can promote the extensive understanding and effective disposal of the spent printed circuit boards in the field of solid waste treatment and resources.

“…In addition silver, lead and tin are present in the solder. The process of recycling of metal from electronic scrap using plasma furnace was also investigated by Jarosz et al [10]. As evident, the recovery of gold from polymetallic sources using hydrometallurgical processes is an complex problem.…”

In this paper, a simple and effective method for gold recovery is described. The paper describes a way to recover gold onto activated carbon from a synthetic solution of gold(III) chloride. The method can also be used on nickel(II) as well as copper(II) chloride of where the metal ion ratios are comparable to the metal ratios found in some electronic waste.With the use of activated carbon in the process of electrolyte purification it is possible to selectively remove gold in metallic form from the solution. XPS studies have confirmed that metallic gold is present on the carbon surface. A spectrophotometric method was used to determine the concentration of Au(III) in the solution. Different concentration of nickel(II) as well as copper(II) were investigated. In all cases, adsorption and reduction of Au(III) to the metallic form was observed.

“…Thus, e‐waste has the potential to significantly impact the economy, human health, and ecosystems. To reduce these potential negative effects, many efforts have been undertaken to recycle the heavy metals found in electronic devices (Matsuto et al ; Méar et al ; Cui and Zhang ; Jarosz et al ; Ilyas et al ). However, several studies have reported that laborers working in e‐waste recycling in developing countries are significantly affected by heavy metals and dioxins derived from brominated flame retardants because of rudimentary and inappropriate e‐waste recycling processes (Guo et al ; Ni et al ).…”

As a result of the continuous release of new electronic devices, existing electronic devices are quickly made obsolete and rapidly become electronic waste (e-waste). Because e-waste contains a variety of metals, information about those metals with the potential for substantial environmental impact should be provided to manufacturers, recyclers, and disposers to proactively reduce this impact. This study assesses the resource and toxicity (i.e., cancer, noncancer, and ecotoxicity) potentials of various heavy metals commonly found in e-waste from laptop computers, liquid-crystal display (LCD) monitors, LCD TVs, plasma TVs, color cathode ray tube (CRT) TVs, and cell phones and then evaluates such potentials using life cycle impact-based methods. Resource potentials derive primarily from Cu, Sb, Ag, and Pb. Toxicity potentials derive primarily from Pb, Ni, and Hg for cancer toxicity; from Pb, Hg, Zn, and As for noncancer toxicity; and from Cu, Pb, Hg, and Zn for ecotoxicity. Therefore, managing these heavy metals should be a high priority in the design, recycling, and disposal stages of electronic devices.
