“…Segundo [Kapoor et al 2021], ao descartarmos um dispositivo eletrônico, por vezes esquecemos que, mesmo tendo sido excluído ou formatado, muitos desses equipamentos ainda contêm dados e informações pessoais que podem ser recuperados. Assim sendo, tais informações confidenciais se tornam alvos fáceis para cibercriminosos.…”

O lixo eletrônico (e-lixo) é um dos problemas socioambientais que mais tem chamado a atenção da sociedade devido ao seu crescente volume, somado ao descarte inadequado. Desse modo, faz-se necessário que os Resíduos de Equipamentos Elétricos e Eletrônicos (REEE) tenham uma gestão adequada que minimize o problema de logística reversa na sua coleta e os impactos ambientais. Sendo esse um tema de extrema importância no contexto de cidades inteligentes, o objetivo deste trabalho é apresentar uma revisão parcial da literatura e uma nova formulação matemática para o problema de Coleta do Lixo Eletrônico (PCLE), descrevendo-o como um problema de Programação Linear Inteira com base em outros modelos semelhantes da literatura, alguns já bastante explorados.

“…For example, an ignorant employee constitutes a significant risk to the cybersecurity of telecommuting as a remote work tool (Okereafor and Manny, 2020). E-waste owners might also be ignorant of the necessary knowledge to recognize the information disclosure risks involved in inappropriate e-waste disposal procedures (Kapoor et al. , 2021).…”

PurposeProtection motivation theory (PMT) explains that the intention to cope with information security risks is based on informed threat and coping appraisals. However, people cannot always make appropriate assessments due to possible ignorance and cognitive biases. This study proposes a research model that introduces four antecedent factors from ignorance and bias perspectives into the PMT model and empirically tests this model with data from a survey of electronic waste (e-waste) handling.Design/methodology/approachThe data collected from 356 Chinese samples are analyzed via structural equation modeling (SEM).FindingsThe results revealed that for threat appraisal, optimistic bias leads to a lower perception of risks. However, factual ignorance (lack of knowledge of risks) does not significantly affect the perceived threat. For coping appraisal, practical ignorance (lack of knowledge of coping with risks) leads to low response efficacy and self-efficacy and high perceptions of coping cost, but the illusion of control overestimates response efficacy and self-efficacy.Originality/valueFirst, this study addresses a new type of information security problem in e-waste handling. Second, this study extends the PMT model by exploring the roles of ignorance and bias as antecedents. Finally, the authors reinvestigate the basic constructs of PMT to identify how rational threat and coping assessments affect user intentions to cope with data security risks.

“…Traditionally, this type of waste is processed by hydrometallurgy and pyrometallurgy [ 2 , 4 , 5 ]. However, these practices continue to produce toxic waste and the emission of harmful agents, which may endanger public and environmental health [ 4 , 6 , 7 ]. For all these reasons, the development of new recycling methodologies with environmental approaches has become one of the most studied topics in the world.…”

“…Overall, recycling processes focus on concentrating the metals of interest (Au, Ag, Cu, Pd and others) in solution or in an ingot for selective separation [ 6 , 9 , 10 , 11 ]. Leaching agents such as thioureas, halides, cyanides and aqua regia are commonly used to separate the gold.…”

Synthesis of Gold Nanoparticles from Gold Coatings Recovered from E-Waste Processors

et al. 2022

This work presents the synthesis of Au nanoparticles from gold coatings recovered from processor pins with minimal waste generation. The process consisted of four main steps: (1) physical recovery of pins, (2) recovery of gold coatings by acid digestion, (3) synthesis of HAuCl4 under mild conditions and, (4) synthesis of Au nanoparticles by the Turkevich method. The small dimensions of Au coatings allowed the synthesis of HAuCl4 with lower amounts of HClconc and HNO3conc than those used with aqua regia. This method has significant advantages, such as lower NO2(g) emission, easy post-treatment and purification, low synthesis cost and high yields. Gold nanoparticles synthesized from HAuCl4 were characterized by transmission electron microscopy (TEM) and UV-Vis spectroscopy. Size distribution analysis showed particles 14.23 nm in length and 12.05 nm in width, while absorption spectra showed a surface plasmon located at 523 nm; these characteristics were very similar to those observed with Au nanoparticles obtained with Aldrich’s reagent. It is suggested that recycling procedures can be improved by taking into account the size and shape of the metals to be recovered, thus introducing a new field of research known as hydronanometallurgy.
