“…The quality of recycled materials or product components in comparison to new materials is an important factor as well (Ravi, 2012). In some cases, recycled components or materials show lower levels or performance than new ones, and manufacturers may need to adapt their product designs to deal with this.…”

Reverse supply chains take a variety of forms, depending on the nature of the product, the business model, the stakeholders and other factors. This article will contribute to a better understanding of how different types of reverse supply chains function, how they can be modelled and their performance assessed. The research is based on a semi-structured approach using case studies, interviews and qualitative analysis. A generic RSC model is suggested in conjunction with an analysis of circumstances and factors of influence, with the intention to trigger further investigation. A better understanding of RSC may lead to more companies engaging in returning products and materials to the process of usefulness suggested by the circular economy concept, hence leading to a more sustainable way of running manufacturing businesses.

Abstract:The amounts of e-waste, consisting of metal (e-metals) and plastic (e-plastics) streams from electronic goods, are increasing in the United States and elsewhere. The e-metals waste streams are being recycled to a reasonable degree due to the value of precious metals. E-plastic waste streams currently are not recycled or reused to a significant extent. As a result, most e-plastics are disposed of by landfilling or thermal treatment, or sent overseas for alleged recycling or reuse, any of which could result in unsafe worker exposure and release into the environment. Two of the major barriers to e-plastics' reuse or recycling are the mixed plastic content and the presence in the e-plastics of flame retardants (FR), of which two classes in particular, the brominated flame retardants (BFR) and organo-phosphorus flame retardants (OPFR), have associated health concerns. The major goal of this project is to investigate the possibility of direct reuse of e-plastics in compression molding. Preliminary data generated have identified a molding procedure that yields remanufactured e-plastics having a tensile strength of 29.3 MPa. This moderate strength level is suspected to be due to inclusions of plastic bits that did not melt and internal voids from out-gassing. Handheld X-ray fluorescence (XRF) was utilized to characterize elemental components in the e-plastics tested for compression molding. Several high "hits" for Br were found that could not be predicted visually. The preliminary XRF data for BFR and OPFR in this work are helpful for environmental and occupational hazard assessments of compression molding activities. Additionally, methods are suggested to characterize the metals, BFR, and OPFR content of the e-plastics using several different additional laboratory analytical techniques to determine the suitability for cost-effective and easy-to-use technologies.

RESUMOAs instituições de ensino superior (IES), responsáveis pela formação de recursos humanos, precisam adotar em sua gestão práticas sustentáveis para atender à legislação em vigor e servir de exemplo a outras organizações e à sociedade em geral. Como a UFABC é uma instituição nova e ainda está amadurecendo os seus processos internos de gestão, o objetivo deste estudo é propor práticas de gestão sustentável direcionadas à otimização da vida útil dos computadores obsoletos tendo como referência o Princípio dos 3 Rs -Reduzir, Reutilizar e Reciclar. A questão de pesquisa, alinhada a este objetivo é a seguinte: como as práticas de gestão dos computadores pessoais do campus da UFABC de Santo André -SP precisarão evoluir para que uma política destinada ao prolongamento da vida útil desses equipamentos possa ser proposta? A metodologia consistiu em levantamento bibliográfico e documental, observação direta e entrevistas. Os resultados indicaram que a Universidade ainda não tem procedimentos sistematizados para a gestão visando à otimização da vida útil dos computadores obsoletos. No entanto, além de já ter práticas para o gerenciamento dos computadores novos, informalmente também já vem reaproveitando peças e componentes de alguns equipamentos condenados ao descarte. Espera-se que os resultados deste estudo possam auxiliar a UFABC a reavaliar as suas práticas atuais e subsidiar a implantação de uma política institucional de gestão de TI enfatizando a ampliação da vida útil dos computadores pessoais. Palavras-chave:Computadores pessoais; Gestão ambiental; Gestão de resíduos; Instituições de ensino superior públicas. MANAGEMENT PRACTICES FOR OPTIMIZATION OF LIFE OF PERSONAL COMPUTERS: A CASE STUDY IN THE CAMPUS OF SANTO ANDRÉ FEDERAL UNIVERSITY IN ABC ABSTRACTHigher education institutions (HEIs), responsible for the training of human resources, need to adopt sustainable practices in their management ways in order to meet the legislation and serve as example to other organizations and society in general. As the Universidade Federal do ABC (UFABC) is a new institution and is still maturing their internal management processes, the aim of this study is to propose sustainable management practices for optimizing the computers life of obsolete equipment. For reference we adopted the principles of the 3 Rs -Reduce, Reuse and Recycle. The research question in line is: how management practices of personal computers of the campus St. André's of UFABC -SP which need to evolve a policy aimed at extending the life of these devices equipment can be proposed? The methodology consisted of bibliographical and documentary survey, direct observation and interviews. The results indicate that the University has no systematic procedures for the management for optimizing the computer life of obsolete equipment. However, the University already has practices for managing new computers, and informally also reuses parts and components from some equipment convicted disposal. We expected that the results of this study might help UFABC to re-evaluat...
