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.

I takt med den ökande befolkningsmängden ställs allt högre krav på företag för att bibehålla de ändliga resurserna. En förutsättning för fortsatt utveckling är effektivisering där resurser används på ett mer effektivt sätt med syfte att minska miljöpåverkan men också ur ett kostnadsperspektiv där företagen ska kunna konkurera eller överleva på den ökande marknaden. Idag läggs mycket fokus på verksamheters flöde i riktning mot konsumenter, allt för att tillfredsställa kundbehov och öka vinsterna. Returflödet inriktas på gods som färdas emot det traditionella flödet för utgående gods och har på senare tid ställts i rampljuset mot ett cirkulärt flöde. Syftet med examensarbetet är att kartlägga returflöden från företag belägna i Orust kommun för att undersöka möjligheterna till effektivisering ur olika aspekter. För att driva studien gjordes en enkätundersökning där 19 företag medverkade genom att svara på 13 frågor berörande dess returflöde, varav 12 angav att de har ett returflöde. Respondenterna undersöktes och placerade ut på kartan för att kunna ge en tydligare bild av nuläget. Från enkäten framgick att nästan alla av respondenterna i studien returnerade sitt gods direkt tillbaka till leverantör i samband med inleverans. De resterande företagen med returflöde angav att de skickade gods till avfallshantering. Företagens returgodstyper varierade från returemballage till farligt gods och frekvensen för returgodset varierade från ett par pall per dag till ett par per år. I dagsläget finns två vägar in till ön i riktning norreller söderut där all godstrafik går. Utefter respondenternas svar konstruerades två fiktiva mjölkrundor med rutt där även de två avfallscentralerna utgjorde en fördelaktig omlastningspunkt för avlämning av avfall med utgång vid respektive bro beroende på godsets slutdestination. Förutsättningar för att en mjölkrunda med konsolidering ska kunna vara applicerbar är att godsets slutdestination ligger åt liknande håll, att returflödesfrekvensen och godstyper är av liknande karaktär. Att transportera avfall i samband med livsmedel är inget alternativ på grund av lagar, men däremot kan exempelvis glasavfall och returemballage returneras i samma fordon. I komplement till den fiktiva mjölkrundan föreslås en utplacering av två nav utanför Orusts gränser med hänsyn till den tunga belastningen på de broar som ansluter kommunen med fastlandet. Naven agerar också mellanhänder för företagens leverantörer som istället för att köra in på Orust, kan hämta upp godset i respektive nav. I den fiktiva lösningen skulle nuvarande transportsträcka på ön minska från 466,6 kilometer till 157,5 kilometer. Trots att samlastning ofta leder till minskad tids- och flexibilitetseffektivitet kan det ur ett miljö- och kostnadsmässigt perspektiv öka effektiviteten för företagen. Den fiktiva lösningen kan på liknande sätt appliceras på fler företag belägna på Orust beroende av verksamhet och plats. / In line with the growing population the demands on companies to act more sustainable are increasing. A prerequisite for continued development is efficiency enhancement where resources are used in a more efficient manner with the aim of reducing environmental impact but also from a cost reducing and social sustainability perspective. The focus is commonly placed on the forward flow of products, often with the goal to make as much money as possible and still please the customers.  The main purpose with this thesis is to map the return flow from companies located in Orust to examine the possibilities to enhance the efficiency from various aspects. To carry out the study, a survey was conducted involving 19 companies responding to 13 questions concerning their return flow. From the survey, it was found that almost all of the respondents in the study returned their goods directly back to the supplier in conjunction with the delivery. The remaining companies with return flow indicated that they sent goods to waste management. The return types of the companies ranged from return packaging to dangerous goods and the frequency of returnees varied from a few pallets per day to a few pallets per year.  There are two bridges over to the island of Orust where all the freight traffic is going: one in the north and one in the south. Following the respondents' responses, two fictional milk rounds were constructed by route where the two waste centers also represented an advantageous relocation point for waste disposal at the end of each bridge depending on the end destination of the goods. Prerequisites for this type of consolidation to be applicable are that the destination of the goods is similar, that the return flow rate and type of goods are of a similar nature. Carriage of waste in the same vehicle as food is no alternative due to regulations, but, for example, glass waste and return packaging can be returned in the same vehicle. In addition to the fictional milk round, a placement of two hubs outside Orust's borders is proposed in due to the heavy burden on the bridges connecting the municipality with the mainland. The hubs could also act as intermediaries for companies’ suppliers who instead of driving into Orust can pick up the goods in their respective hubs. In the fictitious solution, the current transport distance on the island would decrease from 466.6 kilometers to 157.5 kilometers. Although this type of consolidation often leads to reduced time efficiency, it can increase the efficiency of the companies from an environmental and cost perspective. The fictitious solution can similarly be applied to more companies located at Orust, depending on the business and location.

Background It has become increasingly a problem that fashion products reach their end-of-life when they are still usable. Today, a fast-changing wardrobe has gained importance which is directly linked to overloaded landfills of textile waste and scarcity of natural resources. The pressure on companies to act upon this unsustainable consumption pattern is increasing. Different strategies are currently in the development. Within reverse supply chains, products are collected from the original user for value recovery. This study focuses is in particular on the reuse of clothing without additional treatments. Purpose The aim of this study is to investigate the value stream of a traditional fashion retailer entering the second-hand business. At the same time, possible challenges and potential areas of improvement should be identified. The reuse of garments should provide consumers a more sustainable alternative for consumption. To serve this purpose, a case study was conducted to describe key activities and formulate suggestions. Methodology The research was conducted as a qualitative case study. The data collection included personal communication, process observation and an in-depth semi-structured interview. The findings were analyzed using a value stream mapping method. Findings and Discussion The data collection offered a holistic insight into the processes and motivation that are involved in the second-hand concept of the studied retailer. The findings concerning the reverse logistics were depicted in the current-state value stream map. This was adjusted to a possible future-state map based on improvements which were elaborated with the reviewed literature. Additionally, a recommendation for a performance measurement framework was developed. Research limitations The studied retail concept was still at its start-up stage at the time of the research. Therefore, only a limited amount of empirical data was available to collect. Furthermore, the research was conducted over a short period of time and the impact of the recommended improvements for the value stream could not be observed and evaluated. A future research is suggested to focus on the monitoring of the implementation of the future-state map. The success can be assessed with the help of the proposed performance measurement framework and based on that a new future-state map should be created to ensure continuous improvement.

This paper considers a real world waste collection problem in which glass, metal, plastics, or paper is brought to certain waste collection points by the citizens of a certain region. The collection of this waste from the collection points is therefore a node routing problem. The waste is delivered to special sites, so called intermediate facilities (IF), that are typically not identical with the vehicle depot. Since most waste collection points need not be visited every day, a planning period of several days has to be considered. In this context three related planning problems are considered. First, the periodic vehicle routing problem with intermediate facilities (PVRP-IF) is considered and an exact problem formulation is proposed. A set of benchmark instances is developed and an efficient hybrid solution method based on variable neighborhood search and dynamic programming is presented. Second, in a real world application the PVRP-IF is modified by permitting the return of partly loaded vehicles to the depots and by considering capacity limits at the IF. An average improvement of 25% in the routing cost is obtained compared to the current solution. Finally, a different but related problem, the so called multi-depot vehicle routing problem with inter-depot routes (MDVRPI) is considered. In this problem class just a single day is considered and the depots can act as an intermediate facility only at the end of a tour. For this problem several instances and benchmark solutions are available. It is shown that the algorithm outperforms all previously published metaheuristics for this problem class and finds the best solutions for all available benchmark instances.

En esta investigación se propone la implementación de un proceso logístico que involucre el cuidado del medio ambiente de manera efectiva. Actualmente, Wong & Cía. S.A presenta conciencia medio ambiental en sus políticas. Sin embargo, es importante que se consoliden algunas acciones dentro de la cadena logística para que la cadena verde que procede de las empresas extranjeras continúe también en la empresa. Asimismo, se busca integrar acciones que contribuyan a reducir el impacto de la contaminación ambiental en la cual contribuyan los clientes. Es por ello que en esta investigación se realiza un estudio en el que participan dos importantes proveedores y clientes para hacer efectiva la implementación de un área que integre la logística inversa y verde. / This research proposes the implementation of a logistic process that involves the care of the environment in an effective way. Actually, Wong & Cía. S.A presents an environmental awareness in its policies. However, it is important that some actions are consolidated within the logistics chain so that the green chain that comes from foreign companies continue also in the company. Likewise, it seeks to integrate actions that contribute to reduce the impact of environmental pollution, in which customers contribute. That is why in this research a study is made in which two important suppliers and customers participate to make effective the implementation of an area that integrates reverse and green logistics.

No. of bitstreams: 1 Adriano Michelotti Schroeder.pdf: 1352304 bytes, checksum: 8c5cf388d90504afcd0e1f054083d0a5 (MD5) Previous issue date: 2017-06-27 / Electrical and Electronic Equipment have become present in the daily life of people and enterprises. Due to technologies breakthrough that make easier the interconnection of those equipment, regardless of distance, manufacturers, types of models and used operational systems, those equipments have become even more essential, such of being the main factor of changing routines and enterprises processes, extending to the people. Nevertheless, the process of teaching and learning in basic schools and universities has also started to use informatics as a powerful tool, which students can visualize relevant aspects of the subjects through software applications, simulators, immersed in virtual environments, but, very close of reality. However, as those environments require hardware and software compatible with actual informatics scene, the problem of fast obsolescence tends to be more evident, as these new virtual environments require greater computing resources. Those frequent updates of those equipments contribute to make educational institutions to be a potential generator of Waste of Electrical and Electronic Equipments, a kind of waste that demands specifics procedures to correct disposal, to prevent environment and people harm. Therefore, it is natural to set up some obstacles to make the process of correct disposal more difficult, which define the focus of this work, followed by main objective to identify all of those barriers. As benefits, all results of this work will be available to guide future studies to reach out some new appropriate ways to managing and disposal of those kind of wastes, considering minimum financial, social and environmental impacts for educational institutions in São Paulo city. / Os produtos eletroeletrônicos tornaram-se muito presentes no cotidiano das pessoas e das empresas. Com o avanço das tecnologias que possibilitam cada vez mais facilidades de interconexão, independentes da distância, dos fabricantes, dos tipos de modelos e da plataforma operacional em que operam, seu uso tornou-se ainda mais indispensável, a ponto de representarem o principal fator de modificação em rotinas e processos das empresas e até mesmo das pessoas. Não obstante, o processo de ensino e aprendizagem das escolas e universidades também passou a utilizar a informática como uma poderosa ferramenta, à qual os alunos visualizam aspectos relevantes das disciplinas por meio de softwares de aplicativos e simuladores, imersos em ambientes virtuais, mas muito próximo da realidade. Entretanto, como estes ambientes necessitam de equipamentos de hardware e software que acompanhem a questão tecnológica atual, o problema da rápida obsolescência passa a ser evidente, à medida que esses novos ambientes virtuais passam a exigir maiores recursos computacionais. As frequentes atualizações desses equipamentos fazem com que as instituições de ensino sejam potenciais geradoras de Resíduos de Equipamentos Eletroeletrônicos, uma categoria de lixo que demanda procedimentos específicos para que sua destinação final não cause danos ambientais e às pessoas. Assim, é natural que se configurem obstáculos que dificultem o descarte correto deste tipo de resíduo, fato que concentra todos os esforços deste trabalho, tendo como objetivo principal, a identificação dessas barreiras e seus impactos sobre a logística reversa desses materiais. Como benefícios, os resultados deste estudo servirão de norte a estudos futuros, vislumbrando formas mais adequadas de gestão e descarte desses resíduos, com o mínimo de impactos financeiros, sociais e ambientais para as instituições de ensino da cidade de São Paulo.

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.
