Reuse of components as opposed to material recovery, recycling or disposal has been identified as one of the most efficient EOL strategies for products. The concept behind reuse is that some components and subassemblies have a design life that exceeds the life of the product itself. In order for reuse to be successfully implemented as an EOL strategy, a designer needs to incorporate into a product a philosophy of Design for Reuse (DfRe) at the early design stage. Reliable methods to assess the remaining life of used components based on a products usage life are also required. Furthermore, current industry practices and literature advocate that there is no methodology to decide which parameters need to be redesigned so as to change the life of a selected component to a desired level. The objective of this research is to develop a methodology to assess the reuse potential of product groups based on component failure mechanisms and their associated critical lifetime prediction design parameters. Utilising these clustered groups mathematical models were then developed to establish the useful life of the components for each clustered group. Finally, a means of equating useful life to design life was established and the relationship between, the failure mechanisms, critical lifetime prediction design parameters and design life were represented in graphical format. In order to achieve the proposed objective, Cluster analysis, in particular Group Technology (GT) and Hierarchical clustering were employed to group components with similar failure mechanisms. Following this, multiple linear regression was used to establish mathematical models based on condition monitoring data for each of the clustered groups and their related critical lifetime prediction design parameters. A sensitivity analysis was conducted using the mathematical models, in order to produce graphical relations between the useful life and design parameters of a product. The validity of the suggested methodology was tested on electric motors and a gearbox as both these components have demonstrated great reuse potential. The results demonstrate that the methodology can assist designers in estimating the design life and associated design parameters with great accuracy, and subsequently aiding in a stratagem for reuse.

Environmental awareness and legislative pressures have made manufacturers responsible for the take-back and end-of-life treatment of their products. Therefore, manufacturers are struggling to find ways to recover maximum value from returned products. This goal can best be achieved by promoting multiple reuse programs as reuse is one of the most effective ways to enhance a sustainable engineering economy. Since the essential goal of the reuse strategy is to reuse parts, the reliability of used parts becomes a core issue. Research indicates that reuse is technologically feasible, associated with a significant manufacturing cost saving, and it does not compromise product quality. However, it is not easy to be applied in reality. There are several uncertainties associated with reuse, the most common is the uncertainty of the product???s quality after use. A widespread implementation of the reuse strategy could be triggered, subject to the availability of reliable methods to assess the useful remaining life of parts. The evolution of such a methodology would play a pivotal role in making decisions on the supply chain process and the recovery value of returned products. Reliability assessment by life cycle data analysis is the basis of this research. The proposed methodology addresses the problem of reliability assessment of used parts by considering two important aspects. It performs statistical as well as condition monitoring data analysis for decision-making on reuse. The analysis is carried out in two stages. Firstly, a wellknown reliability assessment procedure, the Weibull analysis, is applied to analyse time-tofailure data to assess the overall reuse potential of components. In the second stage, the used capacity (actual life) of components is determined by analysing their operating history (condition monitoring data). The linear and nonlinear regression analysis, Kriging procedures and artificial neural networks (ANN) are employed in this stage. Finally, the Weibull analysis and ANNs are integrated to estimate the remaining useful life of components/assemblies of a product at the end of its first life cycle. The model was validated by using life cycle data from consumer products.

The environmental impact of consumer goods is becoming a growing concern in the modern world. With the increasing awareness of our daily impact and our effects on such crises as global warming, there has been a recent push to develop better environmental strategies and new industries focused on sustainability and the recycling of a variety of post-consumer goods. In other words, there is a shift towards turning waste into money in the name of the environment. Urban regions provide the perfect setting for such development. The concentration of post-consumer waste makes the mining of recyclable materials economical and the availability of labor needed to support the emerging sustainable industries sets the stage for social, economic and environmental benefits. There are currently several end-of-life (EOL) options for post-consumer products. EOL scenarios include secondary material reclamation, material reclamation, repurpose material reclamation, and waste disposal. Within each of these EOL scenarios exists a myriad of process permutations ranging from various collection schemes and modes of transportation to material processing standards and new recycled product industries. Due to the variety of EOL options for post-consumer products, there is no straight-forward answer to the question Which EOL option is preferred? Thus, under the guidelines of Life Cycle Assessment (LCA) as standardized by the International Standards Organization (ISO) in ISO14040, with the inclusion of social and economic requirements as well, the various EOL scenarios are compared in several impact categories including energy use, greenhouse emissions, waste generation, social implications and economic viability. The results of this comparative analysis provide insight into the potential of a more sustainable urban environment, which is part of a much larger goal of reducing our daily impact on the world around us. One industry sector that contributes to a rather large amount of post-consumer trash each year, nearly 4.7 billion tons, is the carpet industry. Carpet thus occupies a great percentage of overall dedicated waste space according to product density. Within an urban environment, the burden of such a bulky waste product is more evident; thus carpet is used here as a case study for the social, economic and environmental impacts of material mining in urban regions for the improvement of overall industrial sustainability. A comparative EOL study is conducted comparing the social, economic and environmental effects of secondary material reclamation, material reclamation, repurpose material reclamation, and waste disposal of post-consumer carpet (PCC) within the thirteen county urban region of Atlanta, GA.

O reaproveitamento de materiais tem sido um tema de grande interesse devido à elevada quantidade de resíduos gerados nas mais diversas atividades. Resíduos de postes de madeira tratada com arseniato de cobre cromatado (CCA) e isoladores elétricos cerâmicos (RIP) são materiais passíveis de reutilização para a produção de madeira plástica. Tais resíduos são gerados principalmente a partir da manutenção de redes de distribuição de energia elétrica. Neste trabalho, foi avaliado o reaproveitamento destes resíduos como agentes de reforços em compósito com matriz de polietileno de alta densidade (PEAD). A madeira tratada foi moída em moinho de facas e os RIP foram moídos em um moinho de bolas. Para a obtenção dos corpos de prova, o PEAD, o agente de reforço e o PEAD graftizado com anidrido maleico (PEADgMA) como agente de acoplamento foram processados em uma extrusora duplarrosca e moldados por injeção. Foi realizado um planejamento experimental 2k para avaliar a influência dos fatores controláveis sobre as variáveis respostas (resistência à flexão e à tração) e assim, identificar a composição da formulação ótima para a obtenção do compósito. Após a identificação da formulação ótima, o planejamento experimental foi validado e foram avaliadas as propriedades mecânicas, morfológicas, térmicas, químicas, reológicas e físicas do compósito. Foram realizados ensaios de lixiviação segundo NBR 10.005/04 e solubilização segundo NBR 10.006/04, para classificar e propor possíveis aplicações para os compósitos obtidos. A adição de 20 % m/m de cada reforço à matriz proporcionou um aumento superior à 50 % na resistência à flexão e tração quando comparado ao PEAD puro. Através das micrografias foi possível identificar a interação entre as fases. As análises térmicas evidenciaram que a adição dos reforços promoveu a conservação das propriedades mecânicas do compósito num intervalo de temperatura superior ao do PEAD. As análises químicas permitiram identificar os grupos orgânicos inerentes a cada matéria-prima na composição do compósito e as alterações devido à degradação provocada pela exposição ao envelhecimento acelerado em câmara UV. A lixiviação apresentou concentrações de As, Cu, Cr e Pb inferiores aos limites permitidos pela legislação, mesmo após 3.024 h de ensaio de envelhecimento, classificando o resíduo do compósito como resíduo classe II – Não Perigoso. Devido à boa molhabilidade da matriz aos reforços, o compósito apresentou baixa absorção de água, baixa densidade e baixo teor umidade. O envelhecimento acelerado apresentou pequenas variações das propriedades do compósito, ao contrário do PEAD, que apresentou fortes reduções em todas as suas propriedades. Dessa forma, produzir compósitos torna-se uma alternativa de reaproveitamento desses resíduos, com destaque para aplicações no setor elétrico, na construção civil e arquitetura, entre outros setores, além de fomentar a gestão de resíduos e reduzir o impacto ambiental. / Submitted by Ana Guimarães Pereira (agpereir@ucs.br) on 2016-12-02T13:01:18Z No. of bitstreams: 1 Dissertacao Jhonattas Muniz de Souza.pdf: 3658517 bytes, checksum: c754c4c4dac0b63953d979c2ceab5ac7 (MD5) / Made available in DSpace on 2016-12-02T13:01:18Z (GMT).

Waste of treated wooden poles with chromated copper arsenate (CCA) and ceramic electrical insulators (RIP) are materials that could be re-used to manufacturing plastic timber. Such wastes are mainly generated from the maintenance of electricity distribution networks. In this work was studied the possibility of reusing this waste reinforcements agents for composites with high density polyethylene matrix (HDPE). The wood was ground in a knife mill and the RIP were ground in a ball mill. To obtain the specimens, HDPE, reinforcing agent and coupling agent were processed in a twin screen extruder and molded by injection. A 2k experimental design was developed to evaluate the influence of controllable factors on the response variables (flexural and tensile strength) and thus identify the optimal formulation composition to obtain the composite. After identifying the optimal formulation, the experimental design was validated and the mechanical, morphological, thermal, chemical, rheological and physical properties of the composite material were evaluated. In addition, leaching and solubilization tests were carried out to classify and evaluate possible applications for these composites. The addition of 20% of each strengthening in the matrix gave an increase up to 50% in the flexural and tensile strength compared to the pure HDPE. The micrographs corroborate with the results of mechanical properties, and it was possible to identify the interaction between the phases. The thermal analysis showed that the addition of reinforcements promoted the conservation of the mechanical properties of the composite in a higher temperature range than the HDPE. The chemical analyzes have identified the organic groups attached to each raw material in the composite composition and the changes due to degradation caused by exposure to accelerated aging in UV chamber. The leaching showed concentrations of As, Cu, Cr and Pb below the limits allowed by legislation, even after 3,024 hours of aging test, classifying the composite waste as non-dangerous, II-A class. Due to good matrix wettability to the reinforcements, the composite had low water absorption, low density and low moisture content. The accelerated aging showed small variations on the composite properties, unlike HDPE, which showed strong reductions in all its properties. Thus, to produce composites becomes an alternative to reuse these wastes, especially for applications in the energy sector, construction, architecture, and other industries, and promote waste management and reduce environmental impact.

In this case study, aggregates and asphalt cement oil (CAP) aged, coming from damaged and subsequently milled through analysis and testing laboratories pavement were analyzed according to each material corresponding to Brazilian Standards (NBR) used in the production of layers the deck, as regards the manufacture of the base and the asphalt coating. The measurement methods for the production of milled mixtures with residual asphalt pavement and their percentages with pure soil were also analyzed, the latter characterized as a low soil bearing capacity in order to achieve the best strength, providing a durability in the underlying layers and reuse of the same milled material for asphalt coating of these layers, with significant savings on their possible applications in future maintenance. Thus, one can avail this stuff to stabilize a soil that did not meet the necessary requirements of the regulatory standards for such purposes, and intuited to give due importance to the concern for environmental issues, which are being addressed particularly sharply in today, minimizing the degradation of deposits of sand and river beds in relation to the removal of boulder, thus decreasing logistics costs, transportation and acquisition of new ones. The experimental results of recycled asphalt mixture to 100% of the milled asphalt pavement waste, evaluated in this study were compared with the results obtained for conventional mixtures and indicated that such a mixture can be used as an alternative for coating urban roads , given the conditions required in regulations on this matter. The ground reference mixtures with milled asphalt pavement residue (RFA) were compatible with the demands of a pavement of heavy traffic volume mechanical behavior. The results were satisfactory, highlighting the positive use of the RFA for application in the base layers of urban pavements. It is noteworthy that studies on the use of this type of waste in pavement, are rare in the city of Manaus and this research adds an exploratory knowledge of their potential applicability. / Este trabalho teve como objetivo estudar a reutilização do resíduo fresado do pavimento asfáltico retirado nas manutenções de vias urbanas. Nesse processo de estudo, foram analisados os agregados e o cimento asfáltico de petróleo (CAP) envelhecido, oriundos de pavimento deteriorado e posteriormente fresado, através de análises e ensaios de laboratórios segundo as normas brasileiras (NBR) correspondentes a cada material aplicado na produção das camadas do pavimento, no que diz respeito à confecção de base e ao revestimento asfáltico. Também foram analisados os métodos de dosagem para a produção das misturas com o resíduo fresado de pavimento asfáltico e suas respectivas porcentagens com o solo puro, este último caracterizado como um solo de baixa capacidade de suporte, no intuito de alcançar a melhor resistência, proporcionando uma maior durabilidade nas camadas subjacentes e ao reaproveitamento do mesmo material fresado para o revestimento asfáltico dessas camadas, com uma economia significativa nas suas possíveis aplicações em manutenções futuras. Assim, pode-se aproveitar esse material para estabilizar um solo que não atendia os requisitos necessários exigidos pelas normas regulamentadoras para esses fins, e no intuído de dar a devida importância na preocupação com as questões ambientais, que estão sendo abordadas de forma bastante acentuada nos dias atuais, minimizando a degradação de jazidas de areia e leitos de rios no que tange à retirada de seixo rolado, diminuindo assim os custos de logística, transporte e a aquisição de novos agregados. Os resultados experimentais da mistura asfáltica reciclada a 100%, do resíduo fresado do pavimento asfáltico, avaliadas nessa pesquisa foram comparados com os resultados obtidos para misturas convencionais e indicaram que tal mistura pode ser usada como alternativa para revestimento de vias urbanas, atendendo os requisitos exigidos em normas referentes ao assunto. As misturas solo de referência com resíduo fresado do pavimento asfáltico (RFA) apresentaram um comportamento mecânico compatível com as exigências de um pavimento de volume de tráfego pesado. Os resultados obtidos foram satisfatórios, ressaltando o emprego positivo do RFA para aplicação em camadas de base de pavimentos urbanos. Ressalta-se que os estudos sobre a utilização desse tipo de resíduo em pavimentação, são raros na cidade de Manaus e essa pesquisa agrega um conhecimento exploratório do potencial de sua aplicabilidade.
