“…The metals present in parts of mobile phone include precious metals (gold, silver, and palladium) as well as toxic metals such as iron, arsenic, cadmium, copper, lead, antimony, tin, palladium, gold, silver and bromine [23]. These metals can leach into soil and water when mobile phones are dumped in open landfill sites with municipal solid waste and pollute the natural environment [16]. Additionally, Goodship and Stevels [11] imply that a mobile phone has 15 or more high-tech materials that make separation challenging and volumes are not high enough to make reuse practical from a technical and economic point of view.…”

The technological advances decrease electrical/electronic product lifecycles and boost consumption of high-tech products. The rapid growth in the electronic market produces electronic waste streams and potential threats arise on sustainability in terms of depleting natural resources and improper disposal. End-of-life electrical/electronic equipment (EEEs) involves complex mixture of materials, has hazardous content, and if not properly disposed, they can cause major environmental and health problems. To prevent the consequences of improper disposal, authorities and researchers conduct large-scale projects aligned with European union legislations. However, these efforts are still not sufficient to establish effective and organized systems due to the problem complexity and the need for specialized arrangements. This study proposes conceptual decision support framework and a bi-objective mathematical model to construct an effective collection network for end-of-life mobile phones. A real case study is presented for constructing an effective collection system in Istanbul. The main reason that we select Istanbul, is the requirement of urgency to deal with the large quantities of ewastes. The result of this study will encourage academicians to conduct further research studies and strongly assist the authorities to configure well-structured ewaste collection system.

“…In particular, advanced shredders have been developed for shrinking the shredding process to a single step. 15,16) Jian-jun et al 17) evaluated the treatment of E-waste to select an environmentally friendly, economical, and socially acceptable treatment method. On the basis of the results of this evaluation, they suggested reselling after refurbishment for short-lifespan refrigerators and pretreatment with complete disassembly and shredding for long-lifespan refrigerators.…”

Size, Shape, Composition and Separation Analysis of Products from Waste Refrigerator Recycling Plants in South Korea

et al. 2014

With the rapid increase in the amount of waste household appliances, there is increasing awareness about finding more efficient ways to reutilize used appliances. There are several plants for recycling household appliances in Korea. The process of recycling involves several stages of shredding, followed by material separation. Given that these plants were built with the technology available at the time of construction, they may not operate at maximum efficiency even as appliances advance with technological improvements in manufacturing. Accordingly, samples were collected from a recycling plant in Korea, and plant performance was evaluated in this study for developing a more efficient recycling process.

Recebido em 7/9/11; aceito em 23/1/12; publicado na web em 15/5/12 PROCESSING OF INK-JET PRINTER CARTRIDGES: AN EXAMPLE OF MANAGEMENT OF A POST-CONSUMPTIONPRODUCT. This work presents a route for processing spent ink-jet cartridges in an experimental course. The disassembly of the cartridges requires several steps and the recognition of their different components is essential to define the best final destination (recycling, co-processing). The plastic strips were chemically processed so as to recover gold and copper. The students recognized the difficulty of processing multicomponent wastes and the importance of the chemical work under the best safety conditions; they also experienced many laboratory techniques and recognized the value of the selective collection and the reverse logistics to reach a viable commercial scale recycling.Keywords: waste electrical and electronic equipment (WEEE); waste management; ink-jet cartridge. INTRODUÇÃOOs equipamentos eletroeletrônicos (EEE) podem ser considerados uma maravilha da ciência, 1 pois a junção dos mais diferentes materiais (plásticos, resinas, metais etc.) permite a concepção de produtos que revolucionam e interagem constantemente com o cotidiano do consumidor, face à extraordinária esfera de dinamismo em que o mundo globalizado de hoje está envolvido. Porém, o ritmo impressionante do crescimento da fabricação e do consumo de EEE, combinado à tendência à redução da vida útil das gerações dos mesmos (obsolescência programada), levam à produção do chamado lixo eletroeletrônico ou resíduos de equipamentos eletroeletrônicos (REEE), que assumiu proporções alarmantes em todo o mundo. Es timativas indicavam que, em 2010, haveria 600 milhões de computadores obsoletos nos EUA. Considerando o resto do mundo, esse número ultrapassaria 3 bilhões. A produção cada vez maior e mais rápida de EEE traz dois gran des riscos ambientais: o elevado consumo de recursos naturais na fabricação destes e a destinação final inadequada.6 Dados de caracterização de diversos EEE indicam que neles podem existir substâncias cujos constituintes contenham até 60 elementos da Tabela Periódica. [6][7][8] Encontram-se nos EEE tanto substâncias com constituintes tóxicos (mercúrio, chumbo, berílio etc.) como metais preciosos (prata, platina, ouro etc.), cada qual com sua finalidade específica. 7,8 Por isso, o primeiro grande impacto do lixo eletroeletrônico não é o seu descarte, mas sim a extra ção dos insumos necessários à sua fabricação. Estima-se que cerca de um milhão de computadores sejam descartados no país por ano.9 A grande parte vai para terrenos baldios, lixões e outros destinos inadequados. A Lei 12305/2010 (Política Nacional de Resíduos Sólidos) prevê nos artigos 30 a 36 (Capítulo III, Seção II) a responsabi lidade compartilhada de fabricantes, importadores, distribuidores e ven dedores na logística reversa para os seguintes produtos pós-consumo: pilhas, baterias, pro dutos eletroeletrônicos, lâmpadas, óleos lubrificantes, pneus e agrotóxicos. 10O ouro pode ser tomado como um exemplo de como...
