Background: There are several strategies that focal companies can opt for to manage their supplychain. Different combinations of configurations and governance mechanisms are argued to havedifferent sustainability outcomes. First, main firms need to decide if they manage the relationshipwith suppliers themselves or if they hire a third party. Second, the buying companies could leadthe relationship with providers by incorporating collaboration or relying on industry certificates.Besides, Swedish companies, as well as Swedish citizens, are claimed to be highly sustainable.Purpose: The goal of this project is to discover the strategies top Swedish companies implementin their supply chains regarding sustainability, and their influence on the position of the companyin the Sustainable Brand Index. As a result, this project will help to determine which specificactions are most likely to lead to increased supply chain sustainability.Method: To fulfil the research purpose, a qualitative study has been conducted. Seven case studies,consisting of five semi-structured interviews with employees from Swedish companies, and twoperipherical secondary-data based ones, were coded and analysed using the grounded analysisfollowing an abductive approach.Conclusion: The results show that the configuration framework available in the literature is notas accurate as it could be, therefore, a new one is proposed. The combination that appeared to havethe best sustainability outcomes entailed a partially closed configuration i.e., extending monitoringto lower tiers, and a spectrum in the governance mechanisms gathering focal company owninitiatives and certifications.

Manufacturing companies have a tremendous environmental impact in terms of the way they manage raw materials. In addition, the amount of waste produced by industries continues to increase, which puts even more significant pressure on the environment. The purpose of this thesis was, therefore, to investigate raw material management and to identify strategies that are implemented in a supply chain in order to reduce waste. Then, an investigation of how these strategies are implemented in the product flow through the focal company, its suppliers, and customers was done.  The single case-study approach was selected to answer the research questions and fulfill the study's purpose. The data was collected through means of interviews and document studies. The theoretical framework presented multiple strategies that can be implemented in order to reduce waste. The butterfly diagram emphasizes waste reduction during different steps in the supply chain using the strategies included in the R approaches. These strategies can be implemented internally within an organization or externally with companies in a supply chain to reduce waste. From the findings and analysis, it was evident that all the companies in the supply chain work actively with sustainability across all parts of the triple bottom line. A product flow mapping was created to visualize the companies’ waste reduction strategies. Recycling was the primary strategy, followed by reducing through quality assurance and a make-to-order approach, then ordering materials close to the finished product dimensions. The companies work individually on sustainability to improve their sustainability practices and achieve sustainability goals. Though, they need to improve collaboration and transparency with the other companies in the supply chain. However, they share a similar view on sustainability, and they are working actively to improve their sustainability work. This has facilitated a sustainable supply chain despite the need for more active collaboration.

[pt] A gestão de resíduos sólidos urbanos domésticos (GRSU) é um problema central nas cidades do mundo inteiro. A quantidade de resíduos produzidos diariamente nessas áreas desafia a sociedade a melhorar suas práticas de gerenciamento de resíduos. Embora países desenvolvidos como a Alemanha tenham alcançado resultados respeitáveis com diferentes iniciativas de GRSU, países em desenvolvimento ainda lutam para ser eficazes com suas políticas. Dado o constante crescimento das favelas, a falta de recursos econômicos, a desigualdade social e a falta de participação dos principais atores do processo, países como o Brasil ainda não encontraram o caminho certo para um sistema sustentável de gestão de resíduos, que é uma parte essencial da gestão sustentável da cadeia de suprimento (SSCM). Embora a literatura ofereça um grande e crescente número de publicações em SSCM e GRSU, há uma falta de estudos ligando os dois temas, especialmente considerando a realidade prática de um país em desenvolvimento. A presente tese visa preencher esta lacuna estudando formas de melhorar a GRSU nos países em desenvolvimento incorporando os conceitos da SSCM a partir da perspectiva da indústria, do setor público e da comunidade local, no sentido de apresentar alternativas para sua melhoria no Brasil. Para isso, foi adotada uma abordagem multimétodo com quatro etapas principais de pesquisa: primeiro, uma Revisão Sistemática da Literatura em SSCM; em segundo, um estudo de caso longitudinal na favela da Rocinha localizada na cidade do Rio de Janeiro (Brasil); em terceiro, uma análise interna e cruzada do GRSU entre duas cidades do Brasil (Macaé) e da Alemanha (Münster); e, finalmente, uma pesquisa com residentes da região metropolitana de Macaé para compreender sua aceitação quanto a adoção das práticas alemãs. A violência presente em favelas brasileiras, assim como a necessidade de moradia em outro país foram os maiores desafios ligados aos estudos de caso citados. Os principais resultados da pesquisa indicam que para enfrentar os problemas ambientais relacionados ao GRSU nos países em desenvolvimento, é necessário resolver questões sociais básicas relacionadas à educação, segurança e infraestrutura, com a integração e apoio do governo, da comunidade local e da indústria. A comparação com o sistema alemão indica que a indústria brasileira ainda está longe de cumprir os pilares social e ambiental do SSCM e deve ser considerada economicamente responsável pelo ciclo de vida de seus produtos, enfrentando o princípio da responsabilidade ampliada do produtor (EPR). Este investimento adicional pode permitir a melhoria das condições de trabalho, investimento em tecnologias e em campanhas públicas regulares para aumentar a educação em assuntos importantes na área de sustentabilidade, levando à formalização da cadeia de reciclagem. Os pilares do sistema alemão (i.e., leis claras, campanhas públicas regulares e a metodologia de taxas) aparecem como uma solução viável para a GRSU nos países em desenvolvimento, porém os resultados da pesquisa indicam que a população ainda não está disposta a pagar (WTP) por todos os custos envolvidos no processo, especialmente aqueles relacionados à coleta/tratamento de recicláveis. Este cenário reforça a necessidade de grandes campanhas educacionais, sobretudo em escolas, que fortaleçam uma visão holística e multi-perspectiva capaz de ampliar a compreensão do problema. Para facilitar esta agenda, também são apresentadas diretrizes para apoiar os formuladores de políticas públicas nos países em desenvolvimento a lidarem com os desafios associados ao GRSU, e para cumprir as Metas de Desenvolvimento Sustentável (MDS) relacionadas. Finalmente, esta pesquisa contribui para que acadêmicos e profissionais forneçam evidências empíricas para enriquecer o debate contínuo sobre o tema, dado que esta não apenas apresenta situações de casos reais em diferentes realidades, mas também destaca questões que devem ser consideradas e gerenciadas na prática, no desenvolvimento e na implementação de técnicas apropriadas para lidar com o GRSU nos países em desenvolvimento. / [en] Urban household solid waste management (UHSWM) is a central problem in cities worldwide. The amount of waste produced daily in urban areas challenges society to improve its waste management (WM) practices. While developed countries like Germany have achieved respectable results with different UHSWM initiatives, developing countries still struggle to be effective with their policies. Given the constant growth of slums, the lack of economic resources, the social inequality, and the lack of participation of the main stakeholders of the process, countries like Brazil still have not found the right path towards a sustainable WM system, which is an essential part of the sustainable supply chain management (SSCM). Although the literature offers a large and growing number of publications in SSCM and UHSWM, there is a lack of studies linking the two themes, especially considering the practical reality of a developing country. The present thesis aims to fulfill this gap by analyzing UHSWM integrating the principles of the SSCM from the perspective of industry, public sector, and the local community, towards presenting alternatives for its improvement in Brazil. To achieve this goal, a multimethod approach with four main research steps was adopted: firstly, a Systematic Literature Review (SLR) in SSCM; secondly a longitudinal case study at the Rocinha slum located in the city Rio de Janeiro (Brazil); thirdly a within and cross-case analysis on UHSWM between two cities from Brazil (Macaé) and Germany (Münster); and finally, a survey with residents of the metropolitan area of Macaé to understand their acceptance of German practices. The violence present in Brazilian slums, as well as the need to live in another country were the biggest challenges linked to the case studies cited. The main research findings indicate that to tackle environmental problems related to UHSWM in developing countries, it is necessary to solve basic social issues related to education, security, and infrastructure, with the integration and support of government, local community, and industry. The comparison with the German UHSWM system indicates that the Brazilian industry is still far from fulfilling the social and environmental pillars of SSCM and should be held economically responsible for the life cycle of its products, facing the principle of extended producer responsibility (EPR). This additional investment can enable improvement in work conditions, in technologies, and on regular public campaigns to increase education in important sustainable matters, leading to the formalization of the recycling chain. The pillars of the German system (i.e., clear laws, regular public campaigns, and fee methodology) appear as a viable solution to improve UHSWM in developing countries, however the research findings indicate that Brazilians are still not willing to pay (WTP) for all the costs involved in this process, especially those related to the collection and treatment of recyclables. This scenario reinforces the need for large educational campaigns, especially in schools, strengthening a holistic and multi-perspective view to increase the comprehension of the problem. To facilitate this agenda, a guideline with feasible alternatives to support policy makers in developing countries to deal with the challenges associated to UHSWM, and to meet the related Sustainable Development Goals (SDGs), is also presented. This research contributes to academics and practitioners providing empirical evidence to enrich the ongoing debate on the topic, as it not only presents real-life case situations in different realities, but also highlights issues that should be considered and managed in a real context to develop and implement appropriate techniques to deal with UHSWM in developing countries.

As CO2 emissions increase, so does the average temperature, leading toenvironmental consequences such as rising sea levels, drought, and starvation.Therefore, it is essential to act towards the reduction of the CO2 emissionsto counteract these dire consequences. The Science Based Target initiative(SBTi) which is a non-governmental organization has created a framework fororganisations to set net-zero targets for 2050. The goals are accompanied byguidelines, demands and recommendations for how to measure and reportemissions across a supply chain. There are challenges and problems attached to measuring CO2 emissions formultinational companies (MNC). The emissions are divided into three scopes.Scope 3 which consists of indirect emissions coming from up- anddownstream of the focal companies has proven to be challenging to gatherdata for due to lack of proper company capabilities. This thesis aims toidentify challenges related to measuring and reporting the emissions caused bythe use of sold products, which is one of the 15 categories of Scope 3.Moreover, this study aims to create a standardized framework for MNCs byaddressing the necessary steps for collecting data for developing an emissionscalculation tool and to suggest how to properly calculate and illustrateemissions ty the focal company. Lastly, the implementability of the frameworkwill be assessed. The research methods include a case study with a set of unstructuredinterviews of nine participants. These includes engineers, innovationmanagers, sustainability managers and product managers. Moreover, aniterative process for developing a calculation tool was performed includingtesting of the tool as it was developed. The case study identified challenges of calculating emissions from soldproducts. These were of lack of IT infrastructure, insufficient data forcalculating emissions, high uncertainties of how the organization shouldconduct measuring of emissions and how to allocate resources in the SBTiimplementation. Moreover, the risks of interpreting calculated dataincorrectly were identified. Lastly, a framework was created consisting of aseven-step process including: communicating transition, assembling projectteams, covering emission, mapping data, creating the tool, task delegation andeducation and standardization.

L'objectiu d'aquesta tesi és contribuir a la gestió sostenible de la cadena de subministrament desenvolupant nous models i tècniques multicriteri per a avaluar proveïdors i clients.

La validació del model en un context real i la seua comparació amb un model alternatiu n'ha demostrat la capacitat per a proporcionar informació rellevant i transparent en la presa de decisions per a l'avaluació sostenible de proveïdors de tecnologia en el sector bancari.

These techniques allow multicriteria evaluations, which are essential for choosing and managing sustainable business partners. The aim of this thesis is to contribute to sustainable supply chain management by developing new multicriteria models and techniques to assess suppliers and customers. Models have been designed in order to incorporate business preferences to make collaborative decisions in the transparent selection and ranking of alternatives based on sustainable criteria. New methods have also been developed to classify alternatives into ordered groups and to assess their quality. Both models and methods have been validated using empirical cases and compared with alternative approaches. The methodology is based on an in-depth literature review, as well as the expertise of supply chain professionals. The proposed multicriteria models integrate techniques such as the Analytical Hierarchical Process (AHP), Multi-Attribute Utility Theory (MAUT) and the PROMETHEE method. Three new algorithms have also been developed for classifying alternatives into nominal and ordered groups (sorting problem). Firstly, a hybrid multicriteria model has been proposed and validated with real data for technology supplier qualifying, selection and ranking. This model integrates compensatory (AHP, MAUT) and non-compensatory (PROMETHEE, FlowSort) methods in a hierarchy with sustainability criteria to evaluate products, suppliers and manufacturers. Validation of the model in a real context and its comparison with an alternative model has demonstrated its ability to provide relevant and transparent information for decision making in the sustainable evaluation of technology suppliers in the banking sector. Secondly, a new algorithm has been designed, called Global Local Net Flow sorting (GLNF sorting), which classifies alternatives into ordered groups based on the net flows generated in global and local searches with PROMETHEE. In addition, the SILhouette for Sorting (SILS) algorithm has been designed to calculate a quality index in the classifications. Both algorithms have been empirically validated in supplier segmentation and their results compared with other published methods. On the one hand, the GLNF sorting algorithm excels in improving the discrimination between suppliers close to the limiting profiles by exploiting the level of preference similarity between alternatives. On the other, SILS improves the quality of alternative assignments to groups, allows for a detailed analysis of suppliers and facilitates decision making. Thirdly, a customer segmentation model based on transactions and collaboration has been proposed in the Business to Business context, applying AHP and GLNF sorting. Validated with 8,157 customers of a multinational company, it has been assessed by SILS and descriptive statistics. This model generates more homogeneous and robust groups than the K-means cluster method. This tool enables companies to automate decisions and perform detailed analysis to improve customer relationships, aligning with their collaboration strategies and market approaches. Fourthly, global and local searches have been used to propose an algorithm for nominal classification based on two dimensions, which provides a very useful strategic matrix for supply chain managers. Finally, the PrometheeTools software package has been developed in R, which automates the implementation of PROMETHEE, GLNF sorting and SILS to solve multicriteria problems of alternatives ranking and classification. This package has been successfully validated and stands out for the efficiency in PROMETHEE and especially when solving problems with thousands of alternatives. It is available by open access in the CRAN repository for use by researchers and practitioners interested in multicriteria decision making. / Barrera Jimenez, IF. (2024).

[pt] Este trabalho tem como base a análise sistemática de literatura para geração de conhecimento sobre o tema de cadeias de suprimentos sustentáveis. Para isso, foram utilizados os métodos de revisão sistemática de literatura e análise de redes, para responder as perguntas de pesquisa: quais são as principais taxonomias sobre o tema, quais são os principais direcionamentos de pesquisa futura e como os temas de cadeias de suprimentos sustentáveis se relacionam. Dessa forma, baseando-se em protocolo metodológico rigoroso e utilização do software Vosviwer, foram identificadas as principais taxonomias sobre o tema, os cinco principais assuntos que os autores mais direcionam como pesquisas futuras e as principais relações geradas a partir das análises de coautoria, co-citação, co-ocorrência. Com base nos resultados, foi possível identificar diversos pontos, como o avanço nos trabalhos envolvendo os pilares de forma integrada, as revisões sistemáticas possuindo metodologia mais robusta que revisões narrativas e o aspecto social como o principal tema indicado para pesquisas futuras. Dessa forma, consolidou-se o que se tem de mais novo na literatura sobre o tema de cadeias de suprimentos sustentáveis, orientando a comunidade científica e outras organizações sobre o assunto, mostrando ainda, os possíveis desdobramentos que podem ser trabalhos. / [en] This paper is based on a systematic literature review to create knowledge on the topic of sustainable supply chains. For this, we used the systematic literature review and network analysis methods to answer the research questions: what are the main taxonomies on the topic, what are the main directions for future research and how are the themes of sustainable supply chain themes related? Thus, based on a rigorous methodological protocol and the use of Vosviwer software, the main taxonomies on the topic were identified, the five main trend subjects were collected and the main relationships identified from the co-authoring, co-citation and co-occurrence analysis. Based on the results, it was possible to identify several points, such as the progress in the work involving the pillars in an integrated manner, systematic reviews having a more robust methodology than narrative reviews and the social aspect as the main theme indicated for future research. Thus, the latest in the literature on the topic of sustainable supply chains was consolidated, guiding the scientific community and other organizations on the subject, and also showing the possible developments that may be work.

La logistique urbaine, et celle du dernier kilomètre notamment, est un sujet de préoccupation majeure pour les villes d’aujourd’hui. Pour répondre à cette préoccupation, nous avons établi dans le chapitre introductif un historique de la problématique de la logistique urbaine pour mieux comprendre son développement au fil des années, permettant ainsi de déduire qu’il est fondamental d’étudier la globalité de la chaîne de distribution dans ce travail de thèse pour mieux résoudre la problématique de la logistique urbaine. En revanche, nous étions confrontés à un sujet redoutable par sa complexité et l’absence de données complètes et fiables. De plus, nous assistons dans les dernières années, à une multiplication des schémas logistiques que ce soit pour la livraison des magasins à partir des entrepôts des fournisseurs ou pour l’approvisionnement des clients à partir des surfaces de vente.De ce fait, nous avons fixé comme objectif d’identifier toutes les organisations logistiques existantes et émergentes en France et ailleurs (deux séjours d’un an en Angleterre et en Suisse). Pour ce faire, nous avons déterminé dans le deuxième chapitre les paramètres de différenciation des modes d’organisation en amont (de l’entrepôt du fournisseur à la surface de vente) et en aval de la chaîne (de la surface de vente au domicile du client). Or il n’existe pas aujourd’hui de bilan économique et environnemental complet permettant d’arbitrer entre différentes formes de distribution classiques et à distance en tenant compte des particularités des familles des produits (non alimentaires, secs, frais, surgelés) et de la diversité de leurs modes de livraison.Face à ces contraintes de taille, nous avons eu recours aux enquêtes de terrain dans ce travail de recherche, qui ont été l’occasion de nouer de très nombreux contacts avec les acteurs de la grande distribution, permettant ainsi de recueillir des données techniques et économiques de première main et inédites jusqu’ici. En plus de la résolution du verrou empirique dans le troisième chapitre, ce travail de thèse a permis également de lever des verrous méthodologiques relatifs à la reconstitution et à l’évaluation des coûts et des émissions logistiques (pour les entrepôts de stockage et les plateformes de transit en amont ; et pour les surfaces de vente et les plateforme de mutualisation en aval) et des coûts et des émissions des véhicules de transport (des articulés et des porteurs en amont ; et des VUL, voitures particulières, transports publics, deux roues, et marche à pied en aval). Enfin, ce travail de thèse a permis d’aboutir à la construction d’une base de données et la mise au point d’un outil d’aide à la décision permettant ainsi de déduire, dans le quatrième chapitre, les bilans économique et environnemental de la globalité de la chaîne depuis l’entrepôt du fournisseur jusqu’au domicile du ménage. Cet outil devrait se révéler très utile pour les politiques publiques, les stratégies futures des grands distributeurs et leurs prestataires logistiques afin de privilégier les modes d’organisation économes et durables, et même pour le client final afin d’estimer les coûts et les émissions de ses actes d’achat dans les différentes alternatives de vente classique et à distance. / Urban logistics and the last mile in particular, is a major concern for cities today. To address this concern, we have established in the introductory chapter a history of the problem of urban logistics. This allows a better understanding of its development over the years, and deducing that it’s essential to study the supply chain in its entirety to better solve the problem of urban logistics. However, we were faced with a daunting task: the lack of comprehensive and reliable data. In addition, there has been a multiplication of distribution channels in recent years. This includes the delivery from warehouses to stores and further to households from the retail space.Therefore, we intended to identify all existing and emerging logistics organizations in France and beyond (one year exchange stay in England and Switzerland for research purposes). To do this, we established in the second chapter certain parameters that differentiate the logistics modes of various organizations upstream (from manufacturers to retail stores) and downstream (from retail stores to households). Unfortunately, there does not exist any economic and environmental assessment to settle between different forms of traditional and modern electronic distribution, by taking into account the various characteristics of different products families (non-food, dry, fresh, frozen) and the diversity of their delivery modes.Faced with constraints of such size, we conducted surveys with different actors of distribution channels, which provided the opportunity to make contacts, thus collect firsthand and so far unpublished technical and economic data. In addition to the resolution of empirical inadequacy in the third chapter, this research also helped to develop a methodological approach related to the reconstruction and evaluation of logistics costs and emissions (in warehouses, transit platforms, retail stores and shared platforms) and also the costs and emissions of vehicles (trucks, delivery van, cars, public transport, bikes, motorbikes and walking).Finally, this research has lead to the construction of a database and the development of a decision support tool to infer, in the fourth chapter, the economic and environmental appraisal of the entire supply chain from the supplier's warehouse to the final customer. This tool can be useful for public policy, future strategies of retailers and Third-Party Logistics providers to focus on efficient and sustainable modes of organization, and even it will benefit the customer to estimate the costs and emissions of its acts of purchase in classic and e-grocery shopping.
