Full textAbstract:
Recycling and remanufacturing returned goods are economically beneficial for companies since the cost of obtaining used parts is lower in many cases and selling price is close to that of a new product. This leads to decreased costs and thereby increased profits for the company. In addition, there are also great environmental benefits by keeping the structural integrity of a part; the energy used for disassembly and refurbishing is much lower than the energy required for raw material extraction and machining. Encompassing the returned goods makes the supply chain to closed loop supply chain, which is different from the traditional supply chain due to reverse logistics. A reverse flow of material is however usually more complex than a forward flow of parts and components from suppliers. This means that inventory management becomes critical and needs to be viewed from a new perspective. The purpose of the report is to study FAW Co., Ltd’s inventory situation in reverse logistics. The report analysed the inventory management in the company, specifically focusing on one product as the instance Motor Engine LFTS-2000since it is in the maturity stage of product life cycle. Two scenarios were designed to consider how different parameters affect inventory levels in reverse logistics. The report analysed how different parameters affect the inventory levels and minimum cost. With the increasing returned goods are processed, inventory levels and minimum cost will decrease correspondingly.

As consumer preferences shift towards online shopping and utilizing their homes as fitting rooms, traditional brick and mortar retailers are faced with the challenge to adapt. Many retailers are experiencing a growing number of returned merchandize, many of which cannot be easily resold to consumers due to various supply chain challenges. This thesis explores the opportunities to improve the consumer returns process and presents methods for modeling the supply chain process for reverse logistics in the retail industry derived from case studies. The model then allows for hypothesis testing. By changing parameters in the model, this thesis further explores the scenarios in which the supply chain process may be improved to increase margin and decrease cost. The primary recommendations include specific modifications to the current reverse supply chain flow, enabling new channels that improve speed and margin, as well as developing the decision tool further for better accuracy and integration into the supply chain.

Full textAbstract:
In recent years, rapid changes in markets including outsourcing and globalisation of trade and production systems have led to a dramatic upsurge of interest in retail logistics with the aim to minimise operational and logistics costs, improve responsiveness and ameliorate customer services. The notable massification and commodification of production and consumption have created structural changes in traditional urban distribution systems with the establishment of peripheral transshipment and hub systems. In the light of sustainable development, green logistics and transparency on emissions have become a further requirement conforming to the times with a special focus being placed on the logistics of collecting, processing and recycling waste materials. This has increased the need to develop more efficient and effective city distribution plans and to establish optimised logistics models which will integrate the delivery of materials and the collection of waste and returns in order to reduce congestion, costs and emissions. To this end, this thesis aims to investigate opportunities to improve existing delivery mechanisms in a dedicated shopping centre in the UK in order to minimise freight activity and emissions, while optimising the reverse flow system for product returns and waste. Using a substantial database of logistics operations compiled for 92 businesses in Southampton’s shopping centre, the study aimed to understand the current opportunities to better utilise the existing back-load capacity and assess the potential logistical and environmental savings that could arise from the use of a peripheral consolidation centre for core goods and waste. Following statistical analysis on WestQuay managers, logistics providers, waste contractors and head offices responses it was found that the fill rates of delivery vehicles were considerably low and therefore there was a great potential to increase back-load rates and consolidation among loads of different businesses. In examining the waste and return flows it was found that there were already centrally managed collections of general waste and some recyclables and therefore further opportunities to reduce the logistics and environmental impact would lie into the consolidation of forward traffic and the back-loading of specific waste streams such as hazardous materials. The examination however of specific case study examples exhibited the variety in the characteristics and properties of hazardous wastes and the role of material-specific legislation on the way different waste streams should be managed and disposed of which limited the collaboration opportunities among businesses producing different waste streams. Instead the study highlighted the considerable transport, environmental and economic gains that could be achieved by individual businesses through the use of regional waste contractors and recycling sites. With regard to the consolidation of forward flows, the study reviewed a number of existing consolidation schemes and their characteristics to identify potential strengths, weaknesses and risks that would impact on the operation of a consolidation centre in the outskirts of Southampton. Various scenarios regarding the operation of the consolidation scheme were examined considering different take up combinations among different vehicle modes and loads. The scenario analysis suggested that the establishment of the consolidation centre could offer great opportunities to reduce the overall urban freight activity, while mitigating the environmental impacts and cutting down the total costs to businesses.

Reverse Logistics and Environmental Considerations in Equipment Leasing and Asset Management

151 Pages
Directed by Dr. Jane C. Ammons
Today many business enterprises employ capital assets in the form of electronic equipment (e.g., personal computers, workstations and peripherals) in large quantities. As a result of rapid technological progress, these products have a very short life cycle, typically not much more than three or four years. Unfortunately, the disposal of electronic equipment (which contains hazardous materials) presents an environmental problem. In the face of rapid equipment changes, current tax laws and disposal challenges, leasing or procurement contracts with take-back considerations are attractive. For a large electronic equipment leasing company, optimal management of assets supported by good logistics decisions is crucial and may provide a significant competitive advantage. The leasing company tries to maximize operating profits through key decisions associated with the length of leases, efficient utilization of logistics facilities for material flow to and from customer sites, and equipment reuse, refurbishment and disposal actions.
In this research, a mixed integer linear programming (MILP) model is developed to facilitate better decisions from the perspective of an electronic equipment leasing company. The model reduces to a linear program (LP) under certain cost assumptions. All computational results are based on the LP version of the model. A case study with representative industry data validates the approach and demonstrates the utility of the model in answering key research questions. Next, important problem uncertainties are identified and prioritized. The effects of these key uncertainties on optimal lease length and product flow decisions are examined in detail via an extended case study. It is also shown how the leasing company can make near-robust leasing decisions in the face of these uncertainties.
The computational research results also have implications for policy formulation on electronic waste. The important insights include an understanding of the potential impacts and expected effectiveness of alternative environmental legislation in different geographic areas, and the imposition of negative externalities on other policy realms as a result of this non-uniform approach. Therefore, this research contributes new models and understanding to the intersection of the fields of reverse logistics and equipment replacement, and provides valuable insights to both business asset managers and environmental policy makers.

Full textAbstract:
Reverse logistics is different from forward logistics in objectives, operations, pricing, quality, quantity, packaging, product and information flow. Further, management of the returned products and their information is a major challenge since it is difficult to predict the time, place of origin, quantity and quality of the goods that will be returned. To establish the importance of reverse logistics as a business process and to understand related issues for information management, this research was undertaken with data from the Australian Manufacturing and E-Business organisations. This research examined six dimensions of reverse logistics. These were: (1) Factors that compel Manufacturing and E-Business organisations to manage reverse logistics; (2) Operations in product return process; (3) Methods of capturing value from returned goods; (4) Barriers to reverse logistics management; (5) Information management issues in reverse logistics; and (6) Product return trends in the E-Business industry. This research was exploratory in nature and was accomplished via a quantitative research method. It adopted a positivist epistemology and followed a deductive approach to capture reverse logistics knowledge. Research data from Manufacturing and E-Business industries was elicited with postal questionnaire surveys using structured questions. Since the data collected from the two main surveys was mainly nominal and ordinal, it was quantitatively analysed using non-parametric tests, Fisher's exact test and one sample Wilcoxon test. It also employed frequency distributions, binomial test and one sample t-test. An additional statistical test was carried out on each set of data to triangulate the finding. The tests were undertaken in Minitab spreadsheet computer packages. This research highlights the fact that reverse logistics management is an important business process in the Australian Manufacturing and E-Business industries. It is a strategic advantage, as well as an important customer service. Although substantial monetary value can be recovered from returned goods, at present two industries investigated have not tapped into this potential. Findings of this research also indicate that a lack of efficient information management is a problem in reverse logistics. Information management in the two industries is based on land-line telephone, fax and computers. This research identified that from E-Business sales error in ordering, customer change of mind on receipt of good and inefficient forward logistics operations (picking, packing and delivery) are important reasons for returns. It also established that e-businesses resell the returned goods and recapture value. The value recovery process in this industry is different from the manufacturing industries where the prevalent value recovery processes are repair, resale and recycle. Further research issues emanating from this project include evaluation methods for recapturing value from returned goods, effective information management strategies for return management and the impact of a law for returning certain types of used goods. This research is an initial effort undertaken to establish returns management in the Australian industries. It establishes that reverse logistics should be recognised as a business process in these industries.

With product returns, reverse logistics management is causing a big environmental impact, especially product returns from online shopping provided by the third-party logistics (3PL) companies. There is a need for understanding in what ways 3PL companies could reduce the environmental impact and at the same time stay competitive. This thesis qualitative method is based on semi-structured interviews with the objective to highlight the management of return transportation. Specifically, the challenges for third-party logistics (3PL) companies to reduce their environmental impact by managing the transportation of product returns and keeping their economic performances. Supporting the study, 3PL companies and end-customers, in Sweden, proposed long-term organized advice (as additional service) to the 3PLs customers for helping them reducing cost and their impact on the environment. The study suggested that 3PL companies are required to emphasize the management of transportation agreements, not only to include adequate economic clauses but also the terms for achieving environmental performances. In the long-term, these agreements will allow 3PL companies to achievetheir environmental performances and remaining competitive. The study recognized that implication for managers might be, for them to keep updated on environmental changes applying that customer’s new demands could require a different way (than today) for managing their logistics organizations. For example, these changes could have great implications for early and consistent managerial actions, impacting the reverse logistics processes, like the transportation of the returned products.

The recycling of household consumer batteries is gaining legislative support throughout North America. The intent of this thesis document is to provide a broad overview of the current North American reverse logistics network for consumer batteries. Topics discussed include the viability of recycling for particular battery chemistries, collection methods, recycling methods, the current legislative environment, and the incentives to participate in the reverse logistics network for the various stakeholders identified. This document culminates in the explicit high-level definition of the available reverse logistics networks and the execution of a global warming potential analysis for each network. It is shown that, of the two available reverse logistics networks, in terms of kg C02 equivalents generated per metric ton of batteries processed one network is approximately double the environmental impact of the other. However, despite the magnitude of this difference, in an overall context this difference may not outweigh other factors for consideration. These other factors include cost, materials recovered, and overall environmental impact which would consider ecosystem quality and human health. This research was conducted using available public information as well as interviews with key individuals who are directly participating in the reverse supply chains.

Verizon may rely on third-party logistics providers (3PLs) to manage some aspects of the reverse supply chain of Fios equipment. As a result, it depends on the 3PL to continually strive for increased quality, reliability, capacity, and speed. Above all, in order to have a successful partnership, the process must be economical for the 3PL. As several sources of variation are detrimental to the 3PL's margins and cause operational problems, Verizon is investing in the supplier relationship to ensure that the 3PL is profitable and positioned for the future. Making sure there is a "win-win" relationship is beneficial for both parties and helps to ensure that the investments that have been made will continue to result in success, including operational improvements. To do this, a culture of continuous improvement and data-driven decisions needs to be cultivated and developed at the 3PL. The goal of this project is two-fold. First, there is a need to understand the variation that exists in the 3PL's process as well as the associated costs, which include overtime, ineffective labor and production planning, and high turnover. The secondary goal of the project is to empower the 3PL to make data-driven decisions in the future and start to shift their culture to one that aligns better with Verizon's. By showing the benefits of collaboration between the two companies, this project will help build trust. In this thesis, we discuss how process mining is used to understand the 3PL's current state and guide data-driven continuous improvement. We introduce several opportunities for handling variation, including creating visibility into return volumes, reducing defects caused by incorrect packaging, and creating feedback mechanisms for operators. This is done in close collaboration with the 3PL to ensure they will ultimately have ownership of implementation.

Full textAbstract:
Supply chain managers in the food and beverage industry face significant challenges regarding the use of effective reverse logistics strategies to reduce supply chain disruptions, control risk, and reduce costs. Through the lens of resource dependence theory, the purpose of this multiple case study was to explore reverse logistics strategies used by supply chain managers in the United States to control cost through risk mitigation. Participants in this study included 5 supply chain managers in the food and beverage distribution industry in the state of Georgia who implemented successful reverse logistics strategies to control cost through risk mitigation. Data were collected using face-to-face, semi-structured interviews and a review of relevant company documents. Data were thematically analyzed using Yin's 5-step process of compiling, disassembling, reassembling, interpreting, and concluding the data. The 3 key themes that emerged from data analysis were a communication strategy, an inspection strategy, and a cost allocation strategy. Supply chain leaders may use the findings of this study to improve their communication flow with internal and external partners, implement an effective inspection strategy to reduce damaged goods, and implement a cost allocation strategy to reduce their financial exposure regarding products in need of return to the original source because of damage or spoilage. The implications of the research for positive social change include the potential for supply chain leaders to lower the cost of food and beverage products for consumers and avoid or reduce the flow of damaged or spoiled food and beverage products into consumer markets through effective implementation of reverse logistics strategies.

Titel: Waste Management – Förbättringsförslag av återvinningsprocessen inom hemelektronikbranschen. Bakgrund: I en bransch som kännetecknas av snabb teknologisk utveckling är det viktigt att se till att de produkter som kommer ut på marknaden också tas om hand på ett bra sätt i slutet av sitt funktionella liv. Hur ser återvinningsprocessen hos företagen ut idag och vad kan göras för att minska de växande problem som framkommer i samband med den ökade konsumtionen? Genom att granska fenomenet Waste Management avser uppsatsen angripa slöseri i logistikflödet och finna förbättringar av dagens återvinningsprocess av uttjänta hemelektronikprodukter. Syfte: Uppsatsens syfte är att kartlägga återvinningsprocessen inom branschen för hemelektronik i syfte att identifiera potentiella förbättringsåtgärder med det samhällsekonomiska målet att uppnå ett större returflöde i logistiksystemet ur ett företagsperspektiv. Metod: Studien utgår från en kvalitativ forskningsmetod som gjorts baserat på en flerfallsstudie. Primärdata har samlats in genom semi-strukturerade besöksintervjuer och asynkrona individuella intervjuer online utifrån ett bekvämlighetsurval. Studien intar ett positivistiskt synsätt och det vetenskapliga angreppssättet är abduktivt. Analysen utgörs enligt en mönsterjämförelse med avseende på produkttyper, kompensation och information till kund. Slutsats: Författarna kommer efter analys av funktionsflödesschema och mönsterjämförelse fram till ett antal punkter för förbättring vilka kan leda till ökad andel återvunna EOL-produkter. Dessa är; införande av ett fast returcenter, omhändertagande av ett större produktsortiment, föra statistik över returer, tydligare information till kund och kompensation för inlämnade produkter. Författarna kommer även fram till att det råder stora skillnader i hur man i dagsläget arbetar med Waste Management inom de olika företagen, där vissa företag är mer ambitiösa än andra. Företagen har mycket att lära av varandra och inom samtliga studerade företag finns något att förbättra.

Full textAbstract:
Background: Increasing awareness for the environmental impact, governments and higher authorities has in the past years issued regulations for waste creation and management, creating a need for new practices and policies on how used material is handled. Reversed logistics could simply be described as the process of ensuring value creation spanning over the entire life cycle. The importance to understand and clarify what differences and limitations the adaptation of reverse logistics in the construction industry present, depending on organisation size. Purpose and research questions: The purpose with this research is to compare how SMEs and large organisations in the construction industry adapt reverse logistics practices. In order to fulfil the purpose two research questions are designed. The first question process what the major differences are between SMEs and large organisations regarding the willingness to adapt reverse logistics. The second question process what the major differences are between SMEs and large organisations regarding the ability to adapt reverse logistics. Method: This research used a qualitative approach. A literature review was conducted to construct a theoretical framework. Ten interviews are conducted with SMEs and large organisation within the construction industry as well an intermediary from a demolition organisation. The interviews are conducted in a semi-structural manner. The interviews are coded in order to define themes and construct a framework. Conclusion: The willingness to adapt reverse logistics depend on the responsibilities the companies have. The larger organisations are willing in order to fulfil larger environmental goals and regulations in the industry whereas SMEs want to ease daily operations and do good to the adjacent community. The ability to adapt reverse logistics are affected by the resources and regulations. SMEs have difficulties in adapting reverse logistics fully because of limited resources relating to handling and storing the to-be-reused material. The larger organisations have the resources but a longer implementation route and with larger projects need the clients demand to adapt reverse logistics on project scale.

Thesis, Linnéuniversitetet, Institutionen för ekonomistyrning och logistik (ELO), 2015. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-44218.
Full textAbstract:
Motivation: Reverse Logistics is part of the concept of Sustainable Supply Chain Management, which is the supply chain consideration of the economic, environmental and social goals of all the stakeholders. These considerations should be balanced in a so-called Triple Bottom Line approach. However, literature approaching the social aspects is almost inexistent and the Triple Bottom Line approach is not common when examining the supply chain problems. The study focuses on companies operating in the Swedish market, since the country is an example in many TBL aspects. Moreover, the study is limited to the fashion apparel industry due to its high amount of returns. Objectives: The purpose of this study is to explain how Reverse Logistics in the fashion industry can contribute to the social dimension of Triple Bottom Line, as well as to identify the tools and strategies used by the fashion companies to balance the trade-offs between the Triple Bottom Line dimensions in the context of Reverse Logistics and explain the reasons behind the decisions. Approach: This is a multiple case study of six companies. Both primary (semi-structured interviews) and secondary (corporate reports and websites) sources were used to collect data. The empirical data was analyzed using pattern matching, first each case individually and thereafter cross-case analyses were performed. Conclusions: The social contribution of Reverse Logistics in the fashion industry is mainly limited to donations to charity. In addition, it is not focused on the workforce, as suggested by the literature. Regarding the trade-offs in Triple Bottom Line, most of the fashion firms do not recognize them in the context of Reverse Logistics. Therefore, companies do not need to prioritize the Triple Bottom Line dimensions or use tools to balance them.

No varejo, questões atuais como o comportamento do consumidor e o gerenciamento de categorias têm sido estudadas por pesquisadores e profissionais. Entretanto, as questões ligadas ao meio ambiente têm ganhado espaço nas empresas varejistas seja por pressão ambiental ou pelo retorno financeiro proporcionado pela reciclagem de materiais. Com o objetivo de analisar as práticas de logística reversa no varejo e como elas podem ser usadas na gestão ambiental, através de um estudo de múltiplos casos, o presente estudo analisou e descreveu três casos de empresas varejistas (supermercados de médio porte) que adotam práticas de gestão ambiental. Os casos são analisados e descritos em suas especificidades de gestão e nos aspectos incrementais dessas práticas. Através da comparação podem-se evidenciar possíveis explicações das diferenças de resultados obtidos com cada um dos casos. Embora os ganhos ambientais, sociais e principalmente econômicos tenham grandes variedades, o estudo mostrou que pode ser um novo campo a ser explorado por outras organizações do varejo.In retail, current issues such as consumer\'s behavior and category management have been studied by researchers and professionals. However, issues related to the environment have been highlighted in business retailers due to environmental pressures or financial earnings provided by the recycling of materials. In order to examine the practices of reverse logistics in retail and how they can be used in environmental management, through a study of multiple cases, this study analyzed and described three cases of retail companies (medium size supermarkets) which have adopted environmental management practices. The cases are analyzed and described in their specific management aspects and the improvement of these practices. By comparison you can highlight possible explanations for differences in results obtained in each case. Although environmental, social and economic earnings have wide varieties, the study showed that it can be a new field to be exploited by other retail organizations.

MBA Professional ReportThe purpose of this MBA project is to evaluate and assess the inventory management database at the Commander, Naval Surface Forces (CNSF) Real-time Reutilization Asset Management (R-RAM) San Diego warehouse. CNSF spends approximately $4 million annually for contractor support to operate the R-RAM warehouses for the Atlantic and Pacific Surface Fleets, and in return receives cost-avoidance for spares issued from the warehouses. The warehouses contain A-condition spare parts that were offloaded from decommissioned ships, as well as excess inventory from afloat units. Spare parts in the R-RAM warehouses were procured either by using initial outfitting allowance or by Operations and Maintenance (O and M) funds. The spare part is issued free to the requesting ship. The R-RAM inventory is visible to customers through the Global Distance Support Center and various databases. The goals of this study of the R-RAM inventory management database are to determine ways to increase throughput while simultaneously reducing inventory and operating expense, reduce inventory footprint by identifying "dead" stock and obsolete spares, recommend a stocking policy, and develop recommendations for current and future operations.

Este trabalho aborda um subitem da Logística Empresarial, a Logística Reversa como uma evolução da administração da cadeia logística e de suprimentos. Neste trabalho será mostrado que a redução na quantidade de produtos ou mercadorias EOL – end of-life ou fim de vida, parados nas lojas de departamento varejistas aguardando devolução, num fluxo reverso, gera receitas positivas para este segmento de empresas se devidamente controlados. Para reduzir esta quantidade à realização de um controle sistêmico por meio de gestão tecnológicas associado à mudança cultural e o desenvolvimento de novos processos de devolução, se faz necessário.This paper addresses a subsection of Business Logistics, Reverse Logistics as an evolution of the management of supply chain and supply. This work will be shown that reducing the quantity of products or goods EOL - end of-life or end of life, standing in retail department stores awaiting return in a reverse flow, generates positive income for this segment companies are properly controlled. To reduce this amount to the realization of a systemic control through technological management associated with the cultural change and the development of new devolution processes is needed.

Full textAbstract:
Background: The demand of textiles and clothing is constantly increasing; as a result the post-consumer textile waste increase as well. This point is bringing the focus on creating the value from waste by recycling. Sweden, municipalities are responsible for handling the textile waste that is currently categorized as the household waste. The post-consumer textile when disposed is mixed with the other household waste, which eliminates the commercial value of the material Purpose: The purpose of this study is to explore the current system in Nässjö municipality to manage post-consumer textiles and identify the possibilities for value creation through reverse logistics processes. Method: To fulfil the research purpose a qualitative study employing single case is used. Study caters multi-perspectives from different actors i.e. municipality, logistics service providers and consumers. Purposive sampling is used to select the respondents from each actor seeing their position in the companies and knowledge on the subject. Primary data is gathered by conducting 11 semi-structured interviews and field visit to the waste collection site. Secondary data is obtained using web sources and also from different project reports from government and other agencies. The empirical data is categorized and then analysed by thematic analysis with the developed theoretical framework of systems’ theory. Findings: Legislation to collect textiles as the separate entity and put it in the reverse logistics system is on the way. Today, input in the system is very low due to the unawareness of consumers about the available options. Municipality is processing the waste as a normal household waste and it is incinerated to produce energy for the residents. LSP are coordinating with municipality and tend to increase their resources for effective participation in the new system. Municipality requires strategic changes to meet the coming legislative requirements. Conclusion: A sub-system could be developed for post-consumer textile in Nassjo municipality. Input in the system has to be determined by consumers education and convenience. Municipality has to define their roles for manage sub-system effectively. The study has provided the rich description of potential possibilities in this context.

Full textAbstract:
Bakgrund och problem: Returlogistik har hitintills varit ett oprioriterat område både inom akademin och i näringslivet, men har på senare tid fått allt mer uppmärksamhet. Många företag arbetar med returflöden eftersom flöden tillbaka från kund förekommer i de flesta branscher, men det är inte något som företag fokuserar på i samma utsträckning som de traditionella materialflödena. Att skapa ett effektivt materialflöde i försörjningskedjan är ingen enkel uppgift, vilket även i allra högsta grad gäller för utformningen av returflödet. Hanteringsprocessen är en viktig del av returlogistiken där varje returprocess kan skilja sig beroende på typ av produkt och hur en organisation ser ut i övrigt. För många företag krävs en lyckad hanteringsprocess för att skapa ett hållbart miljöarbete och lönsamhet i verksamheten. Syfte: Syftet med uppsatsen är att undersöka hur en effektiv hanteringsprocess kan uppnås genom att granska dess krav och förutsättningar samt ta reda på vilka fördelar det kan generera. Genom att utgå från det teoretiska ramverket för vald studie skapas en större förståelse på vilka aktiviteter som ligger i fokus i studien. Med hjälp av figurer och tabeller belyses de krav och förutsättning och uppnådda fördelar inom respektive returprocess som krävs för en effektiv hanteringsprocess. Avgränsningar: Uppsatsen avgränsar sig till hanteringsprocessen inom returlogistik. Vi har alltså valt att avgränsa oss genom att inte beskriva vare sig transporteringen eller insamlingen av returprodukterna. Metod: Studien är baserad på intervjuer som genomförts på de fem företagen: Elgiganten, Skövde Radio och TV-service, Galdax, Skrotfrag och Cementa. Vidare analyseras resultaten av den insamlade empirin med uppsatsens teoretiska ramverk. Slutsatser: Det finns flera anledningar till varför företag bör arbeta aktivt med hanteringsprocessen, detta på grund av de fördelar som kan uppnås genom en effektiv hanteringsprocess. I teorin nämns ett flertal krav och förutsättningar för en effektiv hanteringsprocess, där studien visar att endast en minoritet av dessa verkligen implementeras av företagen. För att uppnå en effektiv hanteringsprocess inom returlogistiken måste företag bli bättre på att uppfylla de krav och förutsättningar som krävs i strävan mot de fördelar som kan genereras. Förslag till vidare forskning: Då hanteringsprocessen inom returlogistik fortfarande är ett ämne som bör forskas mer kring, vore det intressant med vidare forskning inom området och titta mer ingående på de returprocesser som ingår i hanteringsprocessen.

The present dissertation is focused on reverse logistics of construction solid waste. Throughout this work demonstrate the economic hardship and other barriers that companies of this segment, especially infrastructure, face to meet the current environmental legislation and proposes alternatives to the situations encountered by logistics to direct your resources and efforts. What makes this relevant research is increasing the strategic value of solid waste management. More than providing the product within the expectation of the client need to act until the end of the useful life of the goods or services. Fruit of an environmental conscience that gen erated even more challenges and costs for the production process, but that no more ignore the issue of risk the image to the supervision of public authorities. The generation of solid waste is directly proportional to the industrial development and populat ion increase, what's making this increasingly complex issue. The methodology applied to this research can be classified as qualitative, descriptive and applied through a case study developed in an engineering company from Cearà facing metroferroviÃrias act ivities and wind park, demonstrating the involvement of reverse chain of solid waste of the works and their performance. Through the applied questionnaires, unstructured interviews and documentary research, it has been seen that the organization is in the process of implementing an environmental management system. The study concluded that the human factor has a direct impact on the material flow planning. Were pointed to the situations found to direct better the resources and efforts to generate an improvem ent and greater reliability in the disposal of the waste in relation to current situation

Full textAbstract:
Abstract Purpose – The purpose of the study is to identify key-factors for the development of reverse logistics in a distribution central. The study should contribute to cover the knowledge gap that is the problem area: development of reverse logistics in a distribution central. This, since former research primarily deal with the problem area: development of reverse logistics between costumer and focal firm. The purpose of the study has been broken down into two research questions. The first one deals with which forces that affect the development of reverse logistics in a distribution central. Further, important factors for the development of reverse logistics in a distribution central will be identified. Method – The method for the study is an one case study since only one process will be studied. Also, to be able to obtain more profound knowledge within the problem area. The chosen business case is named Ikea distribution central and is located on the industrial area Torsvik. The company is active on the furniture market. The literature collection has been done through four different methods which are: recommendations of search words, recommendations of articles, database searches and snowball sampling. Further, the data collection has been made through interviews, document studies and observations. Finally, the internal validity of the study is high under the circumstance that theories regarding the development of reverse logistics based on B2C is considered to be applicable on the problem area which is based in B2B. Further, the external validity of the study is considered to be low since only one business case was studied. Although, the theory and empiricism of the study has been analysed which in turn strengthens the external validity. Findings – With the collected theories and empiricism as background the authors has produced a basis on which key-factors that are important for the development of reverse logistics in a distribution central. The key-factors that were identified as important and should be taken under consideration is: driving- and hindering forces for the development of reverse logistics in a distribution central, the primary causes of reverse logistics in a distribution central, return avoidance, gatekeeping, supplier relationship management and green logistics. Further, it was discovered that a big factor for a favourable development of reverse logistics in a distribution central was continuous training of the personal simultaneously as the development of the reverse logistics process. Implications – Through the analysis of the study it became clear that a big amount of hinders that can occur in association with the development of reverse logistics, comes as a result of the gap in understanding between the management and the operating core. With this as background the authors of the study recommends that whenever a process is developed, great importance should be added in developing the personal working in the process. Limitations – The limitations which lowers the internal validity and in turn the credibility of the study is that many of the theories used in the study is based on B2C. Another limitation is the choice of one case study since the research questions aimed at obtaining general conclusions. Keywords – Reverse logistics, Return management, Return avoidance, Gatekeeping, Supplier relationship management, Green logistics, Distribution centralSyfte – Syftet med studien är att identifiera nyckelfaktorer för utvecklingen av returlogistik på en distributionscentral. Studien skall bidra till att täcka det kunskapsgap som finns i problemområdet utveckling av returlogistik på en distributionscentral. Detta då tidigare forskning primärt behandlat problemområdet mellan kund och fokalfirma. Studiens syfte har brutits ned i två frågeställningar. Först vill studiens författare ta reda på vilka krafter som påverkar utvecklingen av returlogistik på en distributionscentral. Vidare skall viktiga faktorer för utvecklingen av returlogistik på en distributionscentral identifieras. Metod – Studiens valda metod är enfallsstudie då endast en process studeras, även för att kunna erhålla mer djupgående kunskap om det valda problemområdet. Studiens fallföretag är Ikea distributionscentral som är lokaliserade på industriområdet Torsvik utanför Jönköping och är verksamma inom möbelbranschen. Litteraturinsamlingen har genomförts med hjälp av fyra olika insamlingsmetoder: rekommendation av sökord, rekommendation av artikel, sökning i databaser och snowball sampling. Vidare har studiens insamlade data erhållits genom intervjuer, dokumentstudier samt observationer. Slutligen anses studiens interna validitet vara hög, under förutsättningen att teorier om utvecklingen av returlogistik baserade på B2C även anses vara applicerbara i B2B. Vidare anses den externa validiteten vara låg då endast ett företag har studerats. Dock har teorin och empirin analyserats för att nå generella resultat, vilket stärker den externa validiteten. Resultat – Med studiens insamlade teori och empiri som bakgrund har författarna tagit fram underlag för vilka nyckelfaktorer som är viktiga för utvecklingen av returlogistik på en distributionscentral. De nyckelfaktorer som identifierades som viktiga och bör tas i beaktande var: drivande- och hindrande krafter för utvecklingen av returlogistik på en distributionscentral, grundorsaker för returlogistik på en distributionscentral, return avoidance, gatekeeping, supplier relationship management och grön logistik. Vidare upptäcktes att en stor påverkande faktor för en gynnsam utveckling av returlogistik på en distributionscentral var kontinuerlig utbildning av personal i samband med utvecklingen av sin returlogistikprocess. Implikationer – I studiens analys framkom det att många av de hinder som kan uppstå i samband med utvecklingen av returlogistik handlar om det förståelsegap som finns mellan ledning och den operativa kärnan. Med detta som bakgrund rekommenderar studiens författare att ett företag måste lägga stor vikt på att se till att en utveckling sker både på process-nivå och personal-nivå. Begränsningar – Det som anses begränsa den interna validiteten och i sin tur studiens trovärdighet är att många av de teorier som har använts primärt är grundade i B2C. En ytterligare begränsning är valet av enfallsstudie, detta då forskningsfrågorna och syftet formulerades för att söka generella slutsatser. Nyckelord – Reverse logistics, Return management, Return avoidance, Gatekeeping, Supplier relationship management, Green logistics, Distributionscentral

Full textAbstract:
The returns management (RM) process has traditionally been seen as a value recovery process, which has resulted in an efficiency focus in the returns flow. This thesis present, the effects on a fashion e-commerce organisation, which is underprioritising or neglecting RM in general and consumer returns specifically. In the reported and described single-case study and through a real-life experiment, performed with the case organisation nelly.com, it is shown that the consumer returns rates are not only influenced by the product itself. They represent a complex problem that has its reasons and causes, whereby the product (size, fit, quality, et cetera) together with consumer buying and returning behaviour ultimately have a combined effect on the organisation. The results from the thesis are based on previous research and rest heavily on the research performed since the start of the research journey. Consumer returns form part of the value creation in e-commerce and therefore returns management is a strategic part of the business as such. Handling consumer returns in a traditional or efficient returns system without knowing the reason for return and the state of the returned item is nothing other than gambling with resources. The proposed returns information system (RIS) framework in the thesis addresses this issue and facilitates the downstream application of the gatekeeping activity, near or at the end-user location; managerial attention is required at the strategic process level to build a proper returns system that is partly, and quite likely, decentralised. Products, suppliers, customers and internal processes cause consumer returns and therefore a returns manager needs to address these with other functions and SC partners. This result is partly new and the proposed alignment of RM as a strategic process is new in the sense that RM is part of value creation. This thesis empirically supports the conclusion that “one size fits all” is outdated and does not fit with ecommerce business. The results imply that managers need to gain a profound understanding of consumers’ buying behaviour and also to create differentiated delivery and returns processes to be able to grow within the existing customer segments and possibly to attract new or non-customers who are out of reach at present. Seeing the RM process as strategic in e-commerce, as proposed in the thesis, facilitates the development of the process to become both effective and efficient. Returns management has the potential for revenue creation and cost reduction.Dissertation to be defended in public on 15th of February 2013, at 10.00 in lecture room Vasa C, Vera Sandbergs Allé 8, Göteborg, for the degree of Doctor of Philosophy

Full textAbstract:
Durch immer knapper werdende Ressourcen, steigendes ökologisches Bewusstsein der Konsumenten und nicht zuletzt gesetzlichen Vorgaben sind produzierende Unternehmen über den gesamten Lebenszyklus ihrer Produkte für diese verantwortlich. Dies gilt im Besonderen für Hersteller elektronischer Produkte. Stetige Innovationen und kurze Nutzungszyklen führen dazu, dass noch funktionierende Geräte ungenutzt in den Haushalten lagern oder im Restmüll entsorgt werden. Mit der WEEE-Richtlinie verpflichtete die EU 2003 die Hersteller elektronischer Produkte dazu, nachhaltiger zu produzieren, Ressourcen effizienter zu nutzen, die Schadstoffbelastung und allgemein das durch die elektrischen Geräte induzierte Müllaufkommen zu reduzieren. Mit der Aufgabe diese Ziele zu erreichen, stellen sich die Hersteller somit einer großen Herausforderung. Auf der einen Seite steigt der Druck des Wettbewerbs, die Konsumenten werden zunehmend kritischer und die Rohstoffkosten steigen. Auf der anderen Seite müssen sie eine adäquate Verwertung ihrer Altprodukte finden und deren Rückführung sicherstellen. Dabei sind sie maßgeblich abhängig von der Entscheidung der Konsumenten. Diese können das Produkt kostenfrei entsorgen, jedoch fehlt es ihnen häufig an entsprechenden Anreizen.
Diese Dissertation klärt daher u.a. folgende Forschungsfragen: Welche Möglichkeiten gibt es, die Vorgaben des Gesetzgebers (WEEE) profitabel umzusetzen und wie kann der Konsument in die Planung einer Closed Loop Supply Chain (CLSC) einbezogen werden. Zudem diskutiert sie die Optionen die Handlungen der Konsumenten aktiv zu beeinflussen. Mit Hilfe der spieltheoretischen Modellierung wird ein komplexes dynamisches Modell entwickelt, welches sowohl für den Hersteller als auch für die Endkunden elektronischer Produkte die bestmögliche Lösung vorschlägt. Mit dem entwickelten Modell ist es den Herstellern möglich, ein optimales Produktionsprogramm für mehrere Perioden unter Beachtung einer optimalen Rücknahmestrategie aufzustellen.

Full textAbstract:
The purpose with the study is to provide a basis for an implementable, improved returns management process. This will help to obtain an empirical result for Lager 157 and to fill any scientific knowledge gap. The study has been divided into two research questions that are of a hierarchical nature. The authors first want to map the return process in order to then make suggestions for improvements using collected data along with collected theory. Method – A single case study has been conducted because the authors are studying a process and want a more in-depth knowledge. The study is carried out on Lager 157, who is active in fashion retailing and has a pronounced strategy for omnichannels, where they use both stores and e-commerce. Because the study only is made on one company, the external validity will be low. But the authors will compare collected theory with the empirics, which will increase the external validity. The literature has been collected through different sources, such as; databases, snowballing and recommendations from teachers and fellow students. The methods for collecting data has been; interviews, observations and document studies. Triangulation of data has ensured that the collected data is correct. Findings – The authors have, together with data and theory, provided a basis on how the study company could improve their returns management. The basis stated is that a web-based return registration should be implemented early in the process but also that the stores should use the same ERP as they do in the e-commerce department. These suggestions are based on that the study company should highlight activities such as gatekeeping and return avoidance, which leads to an improved returns management. Because of these changes, the company can increase their process speed but also improve their process integration and take a step towards fully integrated omni channels. Implications –The study has provided with both empirical and scientific implications. The study company has, from the results, got an overview of their returns management but also been provided with suggestions that can lead to an improved returns management in the future. In the results, the study company can also see which effects these suggestions could have and see how the new returns management could look like compared to have it looked before. During the literature study, the authors found that research connected to omni channels and the focused area were missing. Based on this the authors have created a model which illustrates what the companies should prioritize. Because the study only is made on one single company, the authors thinks that there is room for further research where the model could be evaluated and evolved to fit a greater number of companies. Limitations – Because of a time limit of the study, a single case study was considered to be of high relevance. It gave the authors the opportunity to use different methods to collect data in order to strengthen the results obtained. The external validity would have been higher if an multi case study would have been conducted with a quantitative approach. The interviews where following a semi-structured structure because the authors wanted to gather a large amount of information and leave space for follow-up questions. The observations were unstructured in order to make sure that the observation object where acting naturally. On the other hand, a structured observation would have shown differences and deviations in the activities. The document studies were only used to find out which type of data that the study company did collect. This could have been more extensive in a quantitative focus on the study.Syfte – Syftet med studien är att ta fram underlag för en implementerbar, förbättrad returprocess. Detta skall bidra till att få fram ett empiriskt resultat åt Lager 157 samt att fylla igen eventuella vetenskapliga kunskapsgap. Studien har delats in i två forskningsfrågor av en hierarkisk karaktär. Författarna vill först kartlägga returprocessen för att i sedan ta fram underlag för förbättringar med hjälp av insamlade data tillsammans med insamlad teori. Metod – En enfallsstudie har genomförts då författarna ämnar studera en process och vill ha en mer djupgående kunskap. Studien är genomförd på Lager 157 som är verksamma inom mode och har en uttalad strategi för omnihandel, där de använder sig av både butiker och e-handel. Då studien enbart är genomförd på ett fallföretag så kommer den externa validiteten vara låg. Däremot ämnar författarna jämföra insamlad teori med empirin, vilket stärker den externa validiteten. Författarna har samlat in litteratur genom olika tillvägagångssätt, såsom; databassökningar, snöbollsmetoden samt rekommendationer ifrån handledare och medstudenter. De metoder som har använts för att samla in data är; intervjuer, observationer och dokumentstudier. Triangulering av data har säkerställt att den insamlade data är korrekt. Resultat – Tillsammans med insamlade data och teori har författarna tagit fram underlag för hur fallföretaget skulle kunna förbättra sin process. Det underlag som tagits fram är dels att en webbaserad returregistrering bör implementeras tidigt i flödet samt att butikerna och e- handeln bör använda sig av samma affärssystem. Detta underlag har sin grund i att fallföretaget bör lyfta fram aktiviteter så som gatekeeping och return avoidance, vilket leder till en förbättrad returprocess. Effekterna anses bidra till att fallföretaget kan öka sin bearbetningshastighet men också förhöja sin processintegration och ta ett steg mot en fullt integrerad omnihandel. Implikationer – Studien har både tagit fram empiriska och vetenskapliga implikationer. Dels har fallföretaget utifrån studiens resultat fått en överblick i hur returprocessen ser ut men också fått ett underlag med åtgärdsförslag som kan leda till en förbättrad returprocess i framtiden. I studiens resultat kan fallföretaget se vilka effekter detta kan mynna ut i men också hur det nya flödet skulle komma att se ut i de båda kanalerna. Då forskning inom omnihandel kopplat till det studerade området ansågs saknas så har författarna tagit fram en modell som illustrerar vad företag bör prioritera. På grund av att studien enbart är genomförd på ett företag anser forskarna att det finns ett tillfälle för vidare forskning, där modellen kan utvärderas och utvecklas för att passa ett större antal företag. Begränsningar – Då författarna har en tidsbegränsning kopplat till arbetet ansåg författarna att en enfallstudie var av högst relevans. Detta gav även möjligheten för författarna att ta användning av olika datainsamlingstekniker för att stärka de resultat som tagits fram. Om en flerfallstudie hade genomförts med mer kvantitativ datainsamling hade det gett en mer överblickande bild, vilket skulle kunna stärka den externa validiteten. De intervjuer som genomfördes följde en semistrukturerad struktur då författarna ämnade att samla in en stor mängd information och där utrymme fanns för följdfrågor. De observationer som genomfördes var ostrukturerade för att säkerställa att observationsobjekten betedde sig naturligt. Däremot hade en strukturerad observation visat på skillnader och avvikelser i aktiviteterna. Dokumentstudierna användes enbart för att säkerställa vilken typ av data som samlades in i dagsläget och kunde ha varit mer omfattande vid en kvantitativ inriktning på studien.

Full textAbstract:
The current waste management system of Post Consumer Textile Waste (PCTW) in Sweden leads to vast amounts of incinerated or exported textiles. The amount of PCTW reused or repurposed within the country is small in comparison to the amounts of textile products consumed every year. Hence, there is an observed problem in terms of low value creation from textile waste. A system that allows for more textiles to be kept and reused in Sweden could create more economic value in a resource-efficient way. Hence, the purpose of this thesis is to investigate value creation from PCTW for reuse and redesign in Sweden, and to establish a framework for the antecedents of value creation in reverse textile value chains. A pre-study was conducted to map the PCTW industry structure, and served as the basis for sampling cases. Data collection consisted of multiple case studies from 4 charity organisations, 3 clothing brands and 3 redesign brands. The interviews were performed in a semi-structured manner in order to discover the state-of-art in value creation and to identify the key enabling attributes. The findings were analysed to adjust the deductive framework to the textile industry context. Results and findings shows that the state-of-art for value creation among the selected cases varies depending on its mission. Charity organisations are facing a new competition of resources from clothing brands, who have realised a potential of new differentiation by engaging in value creation from PCTW. This has led to a new mind-set among the charity organisations to work more strategically in all their activities. Redesign brands are a relatively new actor and want to work symbolically with redesign to communicate the values in textile materials. Enablers and disablers to value creation from PCTW were found in the interviews and led to the development of an empirical framework. As a whole, this thesis provides rich descriptions of the current preconditions and challenges within the field. Furthermore, it presents a framework for the antecedents of value creation along the recovery processes involved in reuse and redesign value chain. The empirical framework confirms the themes in the theoretical framework, and concludes that there is a set of generic antecedents for value creation in reverse textile value chains. However, there are also category specific antecedents, which need to be considered. The specific experiences of one actor category might as well be valuable knowledge to another, which is why increased collaboration is suggested to enhance value creation from PCTW.

O objetivo precípuo deste trabalho é comparar os programas de reciclagem da USP (campus de São Carlos) e da UFSCar utilizando, como ferramentas de análise quanto ao comportamento dos objetos de estudo, os conceitos da logística reversa e do balanced scorecard. O fundamento para desenvolvimento deste trabalho é a necessidade de novos conceitos e tecnologias para avaliar e comparar o desempenho entre as organizações estudadas e, assim, promover o aprimoramento de seus ideais. O método consiste, primeiramente, em realizar a descrição dos programas envolvendo os aspectos que se relacionam aos canais de distribuição reversos dos resíduos gerados nas universidades. Em seguida, são definidas as perspectivas para a mensuração do desempenho organizacional, divididas em objetivos, indicadores e metas. Aplicaram-se esses indicadores em questionários voltados aos agentes envolvidos com os programas de reciclagem estudados. Os métodos apresentados servem de incentivo para outros programas de reciclagem em universidades do país e para programas internos de empresas preocupadas com a execução de suas estratégias, que não possua um critério de medição do desempenho de suas atividades.The principal aim of this work is to compare the recycling programs of USP/São Carlos and UFSCar using, as analysis tools for that the behavior of the study objects, the concepts of the reverse logistics and balanced scorecard. The basis for development of this work is the necessity of new concepts and technologies to evaluate and to compare the performance among the studied organizations and then, to promote the improvement of their ideals. Firstly, the method consists in accomplishment the description of the programs involving the aspects that relate to the reverse distribution channels of the residues generated in the universities. After that, are defined the perspectives for the measurement of the organizational performance, divided in objectives, indicators and goals.

Full textAbstract:
This study deals with a municipal solid waste management system in which the strategic and tactical decisions are addressed simultaneously. In the system, the number and locations of the transfer facilities which serve to the particular solid waste pick-up points and the landfill are determined. Additionally, routing plans are constructed for the vehicles which collect the solid waste from the pick-up
points by regarding the load capacity of the vehicles and shift time restrictions.
We formulate this reverse logistics system as a location-routing problem with two facility layers. Mathematical models of the problem are presented, and an iterative capacitated-k-medoids clustering-based heuristic method is proposed for
the solution of the problem. Also, a sequential clustering-based heuristic method is presented as a benchmark to the iterative method. Computational studies are performed for both methods on the problem instances including up to 1000 pick-up points, 5 alternative transfer facility sites, and 25 vehicles. The results obtained show that the iterative clustering-based method developed achieves considerable
improvement over the sequential clustering-based method.

The waste electrical and electronic equipment (WEEE) is a sort of waste that has been experiencing significant arising in its generation rates, consisting of a great challenge to decision makers and to society as a whole when it comes to its management. Toxic substances found in WEEE components are also reason of concern. Thus, the correct disposal of WEEE is essential. In Brazil the law 12.305/2010, the National Solid Waste Policy (NSWP) features the correct destination for WEEE, which now have to be included in reverse logistics systems, taking into consideration all the agents of the generation of WEEE process. Therefore, the aim of this study was to develop a general guideline for the management of WEEE, considering the shared responsibility for the waste, having as a study case the city of Uberaba, Brazil. To reach the aim of this study data was collected from different agents that deal with WEEEs, such as retailers, technical assistance companies, cooperatives and other organizations that receive or give a destination to such waste. It has not been possible to estimate the exact amount of WEEE generated in the visited places, once the respondents have no form of monitoring these amounts. However, it has been possible to identify forms of destination of the waste, and the informal sector was shown to be a frequent option for that purpose. It has also been possible to note that most of the interviewed persons have no knowledge regarding the NSWP nor are taking part in actions aiming the development of reverse logistics programs. Suggestions were listed in the end of the work, hoping to contribute towards future programs for WEEE management, taking into consideration the situation observed and other studies developed by others about the subject.
Os resíduos de equipamentos eletroeletrônicos (REEEs) são um tipo de resíduo cujas quantidades geradas ao redor do mundo têm aumentado significativamente, constituindo um grande desafio aos gestores públicos e à sociedade em geral, no que se refere ao seu gerenciamento. A presença de substâncias tóxicas em componentes existentes nesses resíduos também é motivo de preocupação. Assim sendo, sua correta destinação final torna-se essencial. No Brasil, a lei 12.305/2010, que institui a Política Nacional de Resíduos Sólidos (PNRS), dispõe sobre a correta destinação dos REEEs, que devem ser inseridos em sistemas de logística reversa, observando a responsabilidade compartilhada de todos os envolvidos no processo de geração desses resíduos. Dessa forma, o objetivo principal da presente pesquisa foi desenvolver diretrizes para o gerenciamento dos resíduos de equipamentos eletroeletrônicos (REEE), tendo em vista a responsabilidade compartilhada pelo ciclo de vida dos produtos, tendo como estudo de caso o município de Uberaba, MG. Para se alcançar tal objetivo, foram obtidos dados junto a diferentes agentes que lidam com REEEs, sendo eles comerciantes, empresas de assistência técnica em equipamentos eletroeletrônicos, cooperativas e outras organizações que recebem e destinam esses resíduos, indústria, além do Poder Público Municipal. Não foi possível diagnosticar a quantidade exata de REEEs gerada nos locais visitados, uma vez que a maioria não faz controle de sua geração. No entanto, foi possível identificar as formas de destinação de REEEs dos locais visitados e notou-se forte presença do setor informal na cidade (sucateiros, catadores,ferros velhos). Foi possível também constatar que a maioria dos entrevistados não tem conhecimento acerca da PNRS, ou participação em ações visando a logística reversa de REEEs. Algumas sugestões foram listadas, buscando contribuir em futuros programas de gestão de REEEs a serem implantados na cidade, considerando a situação observada e estudos já realizados acerca do assunto.

This paper reports the study of soils contaminated with mineral insulating oil in order to propose remediation processes that are best suited to them. The processes of soil treatment methods involve physical, chemical and biological, and in many cases necessary combination thereof. The proper study of the effects that can be caused by the contamination of the soil above a classification comprising aspects such as adsorption desorption processes, leaching, solubilization, among others. Contaminated soils were used in the Triangulo Mineiro region, the classification being conducted following the procedures described by the Brazilian Association of Technical Standards (ABNT), NBR 10004, NBR 10005, NBR 10006 and NBR 10007. From the obtained results it can be seen that the extent of contamination is limited to the area necessary to saturate the soil in the oil. Under the experimental conditions determined by Brazilian standards contamination is confined to this area, there are no processes and leaching significant. These results propose a great possibility that these remediation for contaminated soils can be implemented in the actual contaminated site without commitment and leaching processes that lead to environmental commitment.O presente trabalho relata o estudo de solos contaminados com óleo mineral isolante com o objetivo de propor processos de remediação que sejam mais adequados aos mesmos. Os processos de tratamento do solo englobam métodos físicos, químicos e biológicos, sendo em muitos casos necessária a combinação dos mesmos. O estudo adequado dos efeitos que podem ser desencadeados pela contaminação do solo precede de uma classificação contemplando aspectos como forma de adsorção de dessorção, processos de lixiviação, solubilização entre outros. Foram utilizados solos contaminados da região do Triângulo Mineiro, considerando a classificação realizada através dos procedimentos descritos pela Associação Brasileira de Normas Técnicas (ABNT), NBR 10004, NBR 10005, NBR 10006 e NBR 10007. Pelos resultados obtidos pode ser verificado que a extensão da contaminação se restringe a área necessária para saturar o solo pelo óleo. Nas condições experimentais determinadas pelas normas brasileiras, a contaminação se restringe a esta área, não havendo processos de lixiviação e solubilização significativos. Tais resultados ensejam uma grande possibilidade de que a remediação para estes solos contaminados possa ser executada no próprio local contaminado sem comprometimento de processos de lixiviação e solubilização que levem ao comprometimento ambiental.

While varies of supply chains are working on moving products towardsthe end consumers, there is also an increasing amount of productsbeing sent back. This has meant an increasing importance of the returnmanagement process. As many businesses have realized that the returnprocess has little connection with their core value, the idea ofoutsourcing return management crossed the mind of many companies.Third-party logistics (3PL) provider have also sensed the opportunityand begun to explore the possibility of providing such services forcompanies in need.

Full textAbstract:
Den linjära Supply Chain modellen och fenomenet ‘Fast Fashion’ som idag karaktäriserar dagens textilmarknad är av ohållbar natur. För att utvärdera hur resurseffektiva de olika verksamheterna i försörjningskedjan är så skapade Carter och Ellram “avfallshierarkin” år 1998. Under 2008 uppdaterade Europaparlamentet och Europeiska Unionens Råd denna modell till det som idag refereras till som “avfallstrappan”. De olika stegen är utformade för att i en önskvärd ordning, minska mängden bortskaffat textilavfall. Ett steg mot en mer hållbar affärsmodell är implementeringen av en grön försörjningskedja (GSCM). De grundläggande förutsättningarna för att kunna använda avfallstrappan är att insamling och sortering av efter-konsument textilavfall (PtCTW) hanteras korrekt och effektivt. ‘ExtendedProducer Responsibility’ (EPR), innebär att företagen har ansvar för hantering av sitt PtCTW, vilket inkluderar insamlings- och sorteringsprocesser. Detta skapar en omvänd försörjningskedja, ‘reverse logistics’. Den omvända kedjan syftar till att skapa ett slutet materialflöde, vilket resulterar i noll avfall. För att kunna göra det måste nya hållbara återanvändnings- och återvinningsmetoder utvecklas. Undersökningen i denna studie syftar till att kartlägga ny teknik inom området för att få reda på huruvida användningen av dessa kan leda till minskad mängd bortskaffad PtCTW.The linear supply chain model and the phenomena of fast fashion that today characterizes the textile industry is unsustainable. To evaluate how resource-efficient the various activities in the supply chain management are Carter and Ellram created the Waste Hierarchy in 1998. In 2008 the European Parliament and the Council of the European Union updated this model to what is today referred to as the waste-staircase (“avfallstrappan”). The different steps are designed for how to, in a desirable order, reduce the amount of textile waste disposed. A step towards a more sustainable business model is the implementation of Green Supply Chain Management (GSCM). The basic prerequisites for using the staircase is that collecting and sorting of post-consumer textile waste (PtCTW) is handled correctly and efficiently. Extended Producer Responsibility (EPR) entails companies to handle their products post consumer phase, including processes such as collection and sorting. This creates a reverse supply chain, ‘reverse logistics’. This reverse supply chain aims to create a closed material flow, resulting in zero waste. In order to do so, new sustainable reuse- and recycle methods needs to be developed. The survey made in this study aims to map new technologies within the area, in order to find out whether the use of these could result in reduced amount of disposed PtCTW.

Full textAbstract:
Syfte – Syftet med detta examensarbete är att bidra med kunskap om hur kvalitetsstyrning av inkommande returflöde kan generera en effektivare återtillverkningsprocess. För att uppfylla syftet har följande två frågeställningar formulerats: Vilka faktorer i returflödet påverkar effektiviteten i en återtillverkningsprocess? Hur kan dessa faktorer kontrolleras för att erhålla en effektivare återtillverkningsprocess? Metod – För att uppnå examensarbetets syfte har en fallstudie genomförts hos återtillverkningsföretaget Recyctec AB i Jönköping. Empirisk data har samlats in med hjälp av intervjuer, observationer och benchmarking. Utöver fallstudien har en litteraturstudie genomförts där ett teoretiskt ramverk skapats. Det teoretiska ramverket har sedan analyserats tillsammans med empirin för att slutligen generera examensarbetets resultat. Resultat – De osäkerhetsfaktorer som författarna identifierat är: drivkrafter för ett återtillverkningsnätverk, osäkerheter i returnerade produkter och kvalitetsbedömning av returnerade produkter. Genom att arbeta med åtgärder för returproduktanskaffning och kvalitetsstyrning för dessa tre osäkerhetsfaktorer kan en effektivare återställningsprocess erhållas. Genom att kombinera olika drivkrafter kan samarbetsviljan i återställningsnätverket ökas. Vidare kan osäkerheten i returnerade produkter minskas genom att dela in kvalitet i olika tydligt definierade och standardiserade kvalitetsklasser. Implikationer – I detta examensarbete föreslås återtillverkande företag skifta fokus från kvalitetskontroller till kvalitetssäkring och lägga resurser där problemen uppstår. Vidare föreslås även en kombination av olika drivkrafter för returproduktanskaffning för att därigenom skapa incitament för returer av bättre kvalitet. Begränsningar – Befintlig teori har fått tolkas och anpassas av författarna för examensarbetet då specifik teori för aktuell analysenhet inte funnits att tillgå. Problemställningarna i återtillverkningsbranschen har visat sig vara branschspecifika och därmed olika. Examensarbetets generaliserbarhet hade därmed kunnat stärkas av ytterligare fallstudier.Purpose – The purpose of this thesis work is to contribute with knowledge about how quality management can generate a more efficient remanufacturing process. In order to fulfill this purpose the following two questions were formulated: 1. Which factors in the return flow affects the efficiency of a remanufacturing process? How can these factors be controlled to obtain a more efficient remanufacturing process? Method – In order to achieve the purpose of this thesis, a case study has been conducted at Recyctec AB in Jönköping. Empirical data has been collected through interviews, observations and benchmarking. In addition to the case study a literature study has been carried out in order to create a theoretical framework. The theoretical framework has been analyzed together with the empirical data in order to generate the result of the thesis. Findings – The uncertainties identified by the authors are: driving forces for the remanufacturing network, uncertainties in returned products and quality assessment of returned products. By working with measures on return product acquisition and quality management for these three uncertainties, a more efficient remanufacturing process can be achieved. By combining different driving forces a higher level of cooperation in the remanufacturing network can be achieved. Furthermore, dividing quality into different clearly defined and standardized quality classes can reduce the uncertainties in returned products. Implications – This thesis proposes remanufacturing companies to shift focus from quality control to quality assurance and to address resources where the problems arise. Furthermore, the authors suggest remanufacturing companies to combine different driving forces for product return in order to create incentives to return products with higher quality. Limitations – Existing theory has been interpreted and adapted by the authors to the thesis, as specific theory for the current unit of analysis has not been available. The problems in the remanufacturing industry have proven to be industry specific and thus different. The thesis generalizability could therefore been strengthened by further case studies.

Syfte – Syftet är att identifiera förbättringsåtgärder i en returhanteringsprocess för produkter med kort livscykel. För att kunna bidra med förbättringsåtgärder till fallföretaget har tre frågeställningar formulerats för att uppnå detta: 1. Hur ser returhanteringsprocessen ut för produkter med kort livscykel? 2. Vilka utmaningar finns det i returhantering? 3. Hur kan processen effektiviseras? Metod – I samtal med fallföretaget och under litteraturstudie identifierades ett problemområde vilket blev grunden för studiens syfte och frågeställningar. Utefter detta genomfördes en enfallsstudie som bestod av observationer och en intervju. Författarna strävade efter en djupgående kunskap av ämnet och därför ansågs enfallsstudie vara lämpligast för studien och dess syfte. För att skapa en grund för hur ett returflöde och utmaningar ser ut byggdes ett teoretiskt ramverk upp baserat på en genomförd litteraturstudie. Tillsammans med den insamlade data och teori analyserades möjliga förbättringsåtgärder. Resultat – Genom att integrera data och teori har möjliga förbättringar kunnat identifierats. En rekommendation är att införa nyckelfunktionen gatekeeping tidigt i returflödet, vilket bidrar till att returer sorteras för att skapa värdeskapande processer i returflöde i en större utsträckning. För att effektivisera ett returflöde kan det analytiska ramverket vara till hjälp för företag samt att betydelsen av att utgå ifrån ett standardflöde. Implikationer – Teorin nämner bristande kunskap inom returhanteringsprocessen, vilket bekräftades av den insamlade empiri där returflödet kan visa en utformning som inte är helt optimalt för produkter med kort livscykel. Det här mynnade ut i att författarna valde att sammanföra två returteorier samt med ett lean perspektiv för att belysa en ny synvinkel med förväntningar att uppnå ett mer optimerat returflöde. Med den nya synvinkeln finns det möjlighet att identifiera värdeskapande processer vilket dagens produktlivscykler kräver för att de idag tenderar att bli kortare. Begränsningar – Studien begränsar sig till en enfallsstudie, vilket medför att trovärdigheten och generaliserbarheten blir lägre. Dock ser författarna fördelar med detta för att de tagit fram ett nytt analytiskt ramverk som först får empiriskt stöd genom denna studie. Vidare krävs det forskning om det analytiska ramverket genererar förbättringar för företag.Purpose – The purpose of this thesis is to identify improvements in a returns flow for products with a short life cycle. Three research questions has been formulated in order to enhance the return flow: 1. How is the returns flow process built for products with short life cycle? 2. What are the challenges in the returns flow? 3. How can the returns process be improved? Method – In conversation with the case company and during the writers literature study a problem area was discovered. This established a foundation for the purpose and research questions. The study was performed as a case study which included observations and an interview. A case study was considered as the most appropriate method for this study since the writers aimed to gather profound knowledge within the subject. A theoretical framework was built upon the literature study to help the writers create an understanding of the returns flow and its challenges. Findings – To be able to identify possible improvements the study integrated data and theory. Recommendations based on this study is to introduce the function of gatekeeping in a returns flow, which contributes to a create a greater value in the returns flow. The analytical framework can help companies to implement better structures for their returns flow and the writers can also recommend to follow one standard which enables a more efficient return flow. Implications – The theory argue that the knowledge is lacking on how to manage a return flow, this is confirmed with the gathered data where the return flow is not designed to create efficiency. To tackle this issue, the writers choose to intertwine two returns flow theories together with a lean perspective. With the integration of these theories, this new viewpoint had the expectation to achieve a more optimal returns flow. This would also give the possibility to find the value creating processes within the returns flow and help to extract as much as possible of the product life cycle. Limitations – The study is limited to a case study, this entails that the credibility and the generalization is low. This is a disadvantage, but this study can be seen as a starting point and therefore the case study is the most suitable. The theoretical framework that is presented in the study also needs practical verification to earn credibility.

Full textAbstract:
In this study, we focus on pricing and production decisions in reusable container systems with stochastic demand. We consider a producer that sells a single product to the customers in reusable containers with two supply options: (i) brand-new containers, (ii) returned containers from customers. Customers purchasing the products may return the containers to the producer to receive a deposit price. The return quantity depends on both customer demand and the deposit price determined by the producer. Hence, the producer has the opportunity to manipulate the return quantity via the deposit price. The unit cost of filling brand-new containers is different than the unit cost of refilling returned containers. We also consider resource restrictions on the production operations. Our setting represents certain hybrid manufacturing / remanufacturing systems where (i) the producer collects and recovers his own products, (ii) the producer supplies both brand-new and recovered products to his customers, and (iii) the customers are indierent between brand-new and recovered products. In this setting, we investigate the optimal pricing and production decisions in order to maximize the producer`s profit. Our approach utilizes non-linear optimization techniques. We characterize the optimal acquisition fee and the optimal order quantity of brand-new containers analytically and investigate the effect of parameters with an extensive computational study.

Com o recente crescimento do cenário industrial brasileiro as empresas precisam se tornar mais competitivas mantendo um desenvolvimento sustentável e obrigatoriamente ainda conseguir respeitar as novas Legislações Governamentais sobre a correta destinação e tratamento dos resíduos industriais. Neste cenário, a logística reversa tem sido observada como uma importante ferramenta de gestão, de sustentabilidade e com alto potencial de integração entre a empresa, o cliente e o meio ambiente. O objetivo deste estudo é avaliar a implantação da logística reversa como um facilitador estratégico para a garantia do desenvolvimento sustentável. Este estudo se enquadra como pesquisa exploratória, de abordagem qualitativa, com delineamento bibliográfico e documental utilizando a abordagem de estudo de caso. Teve como objetivo avaliar a aplicação dos conceitos da logística reversa com o foco no desenvolvimento sustentável em uma estamparia de peças metálicas automotivas. A exploração dos dados realizada através dos documentos de produção e qualidade da estamparia em questão, comparados com os padrões mundiais neste segmento, possibilitou a geração de tabelas de resíduos separados por categorias de materiais. Verificou-se que a logística reversa bem aplicada à destinação destes resíduos, permitirá a estamparia desenvolver um foco estratégico e sustentável com a aplicação de um fluxo correto no descarte estruturado para a recuperação e a reciclagem dos produtos. Concluiu-se que nas questões ambientais a logística reversa auxiliará na preservação dos recursos naturais do meio ambiente, direcionando os resíduos para os locais corretos de descartes, auxiliando as empresas na criação da educação ambiental junto aos seus consumidores.With the recent growth in the Brazilian industrial companies need to become more competitive while maintaining sustainable development and still be able to comply with the new Government Legislation on the correct disposal and treatment of industrial waste. In this scenario, the reverse logistics has been observed as an important management tool, sustainability and with high potential of integration between the company, the customer and the environment. The aim of this study is to evaluate the implementation of the reverse logistics as a strategic enabler for the guarantee of sustainable development. This work fits as exploratory research, qualitative approach, with bibliographic and documentary delineation using a case study approach. Aimed to assess the application of the concepts of reverse logistics with a focus on sustainable development in a stamping of automotive metal parts. The exploitation of data held through the documents of production and quality of printing in question, compared with world standards in this segment, made possible the generation of tables separated by categories of waste materials. It was found that the reverse logistics well applied to the disposal of this waste, allow the stamping to develop a sustainable and strategic focus by applying a correct flow in structured disposition for the recovery and recycling of products. It was concluded that the environmental reverse logistics will assist in the preservation of natural resources on the environment, targeting the waste to the correct locations of discards, aiding companies in the creation of environmental education together with its consumers.

Full textAbstract:
One of the newest emerging areas of research in supply chain management is ReverseLogistics. It involves all activities related to the flow of products from the customerback to the supplier. In the last decade scholars have developed theories and models,however empirical data is still in its infancy. In response, this paper strives to close thisgap by conducting research to create new knowledge on the first element of reverselogistics, which is the product return process. The main intention of having a returnprocess is to handle returned products efficiently in order to recover value and to savecosts. Therefore, it is a value-adding operation and can become profitable for thecompany.The purpose of this study is to investigate the implementation and perception of thereturn process of Swedish e-retailers. Sweden is considered to be one of the mostmatured e-commerce markets. In addition, e-retailers experience the highest rate ofproduct returns. Together those two factors influenced the decision to dedicate thisthesis to this particular region and industry.Initially, this paper introduces reverse logistics focusing specifically on the productreturn process. An overview of the existing theories and concepts within the returnprocess is presented and summarized, resulting in the creation of the Boomerang ReturnModel. Based on this foundation the questionnaire was created. By cooperating with theSwedish e-retail federation - Svensk Distanshandel, access to the industry was gained toperform a quantitative study.It was found that the empirical data only gives insight into the implementation andperception of the return process of small sized companies. The findings demonstrate thelimited awareness of the importance of an efficient return process. Companies tend toperceive the return process as unimportant instead of value adding. Hence, there is anopportunity for improvements in the Swedish e-retail market. From these findings amodified version of the Boomerang Return Model was created to adjust the initialmodel particularly for small sized companies. The model can be utilized as a theoreticalgroundwork in future research. Additionally, it could also serve as guidance for smallcompanies how to implement an appropriate return process.

As cadeias reversas de suprimento fazem parte do nosso cotidiano. O aumento da sua popularidade ocorre, principalmente, pela expansão do comércio online, onde estão estabelecidos os canais reversos de troca; de devolução em garantia; e por cancelamento da compra. No segmento industrial, os canais reversos são muito populares, como por exemplo, o retorno de embalagens de produtos, o retorno de resíduos industriais para reprocessamento ou destinação final, e o retorno de materiais pós-consumo para o reaproveitamento. Na indústria do aço, a cadeia reversa da sucata metálica é responsável pela gestão do fluxo reverso dos materiais metálicos usados desde o consumidor até o seu ponto de origem, a usina siderúrgica. O aço possui a característica de ser 100% reciclável, sem perdas de propriedades do metal; além do seu processo de reciclagem representar vantagens econômicas e ambientais. A pesquisa propõe o resgate conceitual sobre a estruturação de atividades das cadeias reversas e o gerenciamento de riscos nas cadeias de suprimentos. Através da combinação destas abordagens, elaborou-se uma estrutura geral de atividades, bem como a identificação dos riscos dos intermediários da cadeia da sucata metálica. Como resultado, a pesquisa não limita-se a apresentar a estrutura genérica de atividades e as ações de prevenção dos riscos da cadeia da sucata, mas evolui através proposição de uma metodologia de gerenciamento de riscos aplicável a qualquer cadeia reversa de diferentes segmentos industriais.
The reverse supply chains are part of our daily life. The increase in their popularity is mainly the expansion of online commerce, where the reverse exchange channels are established; of warranty return; and purchase canceled. In the industrial sector, reverse channels are very popular, such as the return of product packaging, industrial waste comeback for reprocessing or final disposal, and the return post-consumer materials for reuse. In the steel industry, the reverse chain of scrap metal is responsible for managing the reverse flow of metallic materials used from the consumer to their point of origin, the steel milling. Steel has the characteristic of being 100% recyclable without loss of properties of the metal; apart from its recycling process represent economic and environmental advantages. The research proposed the conceptual review of the activities of structuring reverse chains and supply chain management risk. By combining these approaches, it drew up a general framework of activities, as well as recognition of the risks of the intermediaries of the scrap metal supply chain. As a result, the survey does not limit to presenting the generic structure of activities and mitigation risk actions in scrap supply chain, but evolves through proposing a risk management methodology applicable to any reverse chain of different industries.

Full textAbstract:
Aujourd’hui, la compétition croissante, l'expansion des marchés et les progrès de la technologie engendrent un raccourcissement du cycle de vie des processus de développement des produits afin d’en améliorer les performances en termes de délai, coût et qualité. Ce raccourcissement du cycle de vie a engendré un accroissement des volumes de déchet généré et des conséquences que cela peut avoir sur l’environnement. Au niveau de l’Union européenne, des directives ont été introduites, tels que la gestion des déchets d'équipements électriques et électroniques (WEEE), la restriction de l'utilisation de certaines substances dangereuses dans les équipements électriques et électroniques (RoHS) et les directives pour le traitement des batteries usagées (Battery); ces directives permettent de limiter l'utilisation et le recyclage des substances dangereuses nocives pour la santé et pour l'environnement.Ces nouvelles réglementations et normes, permettant de gérer de manière efficace les retours et la fin de vie des produits (recovery process), ont été mises en place afin d'obliger les entreprises à assumer leurs responsabilités en termes de gestion des produits en fin de vie. Certaines entreprises ont montré que les produits recyclés ou réutilisés peuvent être une source supplémentaire de revenu (recyclage des matériaux, ou réutilisation des composants après démontage) dans le processus de fabrication.Ces connaissances liées à la performance environnementale (au niveau des processus de conception, de production, de transport, d’entreposage, de récupération…) devraient êtres saisies, évaluées et capitalisées dans des bases de connaissances afin d’être prisent en compte durant les différents phases du cycle de vie des produits.Nos travaux de recherche proposent donc de développer une architecture de gestion des connaissances (Knowledge Management Architecture) basée sur un Système Multi-Agents. L’objectif est de proposer un système qui met l'accent sur les concepts de « durabilité des produits et des cycles de vie », en établissant des liens entre des Agents Logiciels détenteurs de connaissances liées à la réglementation environnementale et les Systèmes d’Information de type PLM. Ces interconnexions permettront aux décideurs de prendre en compte les impacts environnementaux dans leurs décisions et ceci à chaque phase du cycle de vie des produitsThe increasing of competition, expanding markets and advanced technology create shorten lifecycle and the development process to improve product performance in terms of time, cost and quality. These shorten products lifecycle have led to increase volumes of waste generation and consequence impact to environment. EU directives have been introduced, such as Waste Electrical and Electronic Equipment (WEEE), Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS) and guidelines for the treatment of waste batteries (Battery), these directives are used to handle the hazardous substances which are harmful to human health and the environment.These regulations and standards have been put in place to force companies take their responsibilities on managing their products when reach to the end of life. Some companies have found that the returned product can be recycled or reused as an additional source of income (material recycling, or reuse of components after disassembly) in the manufacturing process.Knowledge related to the environmental performance (in terms of process design, production, transportation, storage, etc.) should be captured, evaluated and stored in knowledge base in order to share between users in different phases of the product lifecycle.Therefore, this research proposes a Knowledge Management Architecture based on a Multi-Agent System approach. The objective of this work is to propose a system that focuses on the concept of "sustainability” of products lifecycle by establishing the link between agents, who hold knowledge related to the environmental performances, and PLM system. The connection encourages companies considering the environmental impacts in their decision making at every stage of product lifecycle
