M. Tech. (Department of Logistics Management, Faculty of Management Sciences), Vaal University of Technology. / In South Africa, the beverage industry is perceived to be a major contributor to the economy. Internal and external stakeholders in this industry are engaged in environmental collaboration with each other to achieve better environmental and supply chain performance. The aim of this study was to investigate the influence of green supply chain management practices on environmental performance and supply chain performance in the beverage industry of South Africa. It considers four of these practices, namely, internal environment management, investment recovery, eco-design and green purchasing. A quantitative approach was adopted, with the use of a survey questionnaire to collect information from 373 supply chain management professionals from beverage companies in South Africa. The study used a probability simple random sampling method. The data gathered was analysed using the Statistical Package for the Social Sciences (SPSS) version 25.0 and Analysis of a Moment Structures (AMOS) version 25.0. A Confirmatory Factor Analysis (CFA) was used to validate the measurement scales while Structural Equation Modelling (SEM) was applied to test the relations between constructs. The results revealed that internal environment management, investment recovery, eco-design and green purchasing positively and significantly influence environmental performance. Moreover, the results also revealed that environmental performance exerted a strong, significant and positive influence on supply chain performance. Recommendations and implications for further research were made based on these results. The study presents supply chain management professionals, internal and external stakeholders within the beverage industry with useful insights on key factors that ought to be addressed in order to improve their organisational strategies. Therefore, the study is essential to internal and external stakeholders in the beverage industry who wish to improve environmental and supply chain performance.

In order to reduce the environmental footprint of products, companies turn to Eco-design and associated tools. Life cycle assessment (LCA) is a holistic and quantitative tool that is widely accepted in companies, but it is too extensive to apply in product development; as an alternative, simplified versions are more suitable. By utilising CAD models of components, material data and a database, weight can be calculated and LCA data estimated. This thesis aims to evaluate the feasibility of utilising CAD-integrated LCA software in product development process and explore the barriers in doing so. A case study was conducted to evaluate the software Sustainable Innovation Intelligence by thoroughly describing the tool, the database used as well as the product life cycle management (PLM) system used. Two research questions have been formulated regarding the barriers and to what extent they can be overcome using the new CAD-integrated tool. The first one is answered by a literature review, where 22 barriers were identified and related to different sociotechnical levels, while the second is answered by using pattern matching following the case study. The evaluation covers human and technical aspects of the tool itself, what is required by the practitioner, as well as additional aspects to consider when implementing the tool in a company. The final result shows that 11 of the barriers are to some extent being overcome by the tool. While showing promise, the novelty of the software makes it immature and lacking full functionality, while requiring a lot of the practitioner in terms of LCA specific knowledge.

I takt med att världen genomgår kriser i form av pandemi, ändrade handelsvägar, inflation och naturkatastrofer, förändrar det även förhållanden för textilproduktion. Från att företag flyttat sin produktion mot Asien på grund av låga produktionskostnader, börjar trenden skifta tillbaka till att företag väljer att flytta hem sin produktion. Syftet med studien är att utforska i vilken utsträckning ekodesigndirektivet, och FN:s mål för Agenda 2030 påverkar beslutsprocessen för en eventuell hemflyttning av textilproduktion till Sverige och Europa. En explorativ undersökning har gjorts på tre svenska modeföretag, där två personer per företag har givit sina inställningar och åsikter i semistrukturerade intervjuer. Resultatet visade att det finns en viss medvetenhet hos företagen kring ekodesigndirektivet, och en tydlig medvetenhet om Agenda 2030. I dagsläget påverkar ekodesigndirektivet eller Agenda 2030 beslutsprocessen för en eventuell hemflyttning av produktion till en liten grad, men företagen ser sitt ansvar i att vidareutbilda sig och vara rustade för nya regelverk, i form av att implementera dels CSR-aktiviteter, men även anställning av spetskompetenser. För att kunna flytta hem sin produktion krävs det innovationer i form av teknologi, som Sverige och Europa bör vara beredda att investera i trots det faktum att de flesta länder inom området har höga arbetskraftskostnader. Framtidens råmaterial i form av spillmaterial från gamla textilier, är också en möjlighet för området att generera. Om så är fallet, kan man utgå ifrån Sverige och Europa när man ser till hela värdekedjan, vilket betyder att den kan bli desto mer transparent och spårbar. Uppsatsen är skriven på svenska. / As the world contends with crises such as pandemics, shifting trade routes, inflation, and natural disasters, it also reshapes the landscape of textile production. While companies previously redirected their production towards Asia due to low production costs, the trend is now beginning to shift back as companies opt to relocate their manufacturing back home. An exploratory investigation was conducted with three Swedish fashion companies, where two representatives from each company provided their perspectives and opinions through semi-structured interviews. The results revealed that there is some awareness among companies regarding the Eco-design Directive and a clear understanding of Agenda 2030. Currently, the Eco-design Directive or Agenda 2030 only marginally influences the decision-making process for potential production reshoring. However, companies acknowledge their responsibility to further educate themselves and prepare for new regulations by implementing CSR activities and hiring specialized expertise. To relocate production back home, innovations in technology are required, which Sweden and Europe should be prepared to invest in even though most countries in the region have high labor costs. Future raw materials in the form of waste materials from old textiles also present an opportunity for the region to capitalize on. If so, Sweden and Europe could become the focal point for the entire value chain, making it more transparent and traceable. The paper is written in Swedish.

This investigation strives to determine the level of ecodesign awareness as well as to map the use of methods and tools for this concept in the electrical and electronics industries of Thailand. The foundation of the thesis is eight semi-structured qualitative research interviews performed with various people at Thai organisations, an electronics manufacturer in Thailand, and experts from Swedish, Danish and Thai universities. The research method has yielded the following results: The level of ecodesign awareness within the country is low, and so is the general level of environmental knowledge. The concept of Life Cycle thinking is mostly unknown, and at best used only to parts of its full potential. The ecodesign education is limited to basic courses at university level and much of the problems with the use of methods and tools for ecodesign can be traced to the lack of ecodesign knowledge amongst its presumptive users. Respondents of this research suggests that the ecodesign knowledge and awareness is significantly higher amongst larger companies with foreign connections than it is amongst Small and Medium sized Enterprises of Thailand, which often have no such contacts. At present, efforts are being made to educate Thai companies in ecodesign through networking, seminars, workshops and student/expert internships. These endeavours have been arranged by various organizations with the aid from foreign experts and have resulted in successful ecodesign/redesign of products within Thailand. Stakeholder demands such as cost-down or legislation compliance demands are the main driving forces for ecodesign in Thailand, and very few attempts at ecodesign for the pure benefit of the environment are being made. Present trends suggest that the future of ecodesign in Thailand will include the finalisation of a Thai-RoHS directive and possibly further work on a Thai-WEEE directive as well. As for Life Cycle thinking, practices of Life Cycle Assessment (LCA) are still basic, but some uses of such LCA tools as SimaPro and GaBi have been proven. Commercial LCA software licenses are considered expensive by most Thai companies and it has become common practice to utilize licenses bought by organisations instead of buying licenses for one’s own company. This results in high costs having to be carried by the organisations and diminishes investment possibilities in other ecodesign fields. At current, LCI data is being requested by companies and might lead to more work being made in this area in the future. In conclusion, more effort needs to be put into education on all levels and the application of educational methods and tools is advised.

Eco-design is relatively new and fast growing field of research due to its vital importance to the manufacturing industry and its related environmental issues such as reducing waste, and CO2 emission. A major EU programme relating to the environment is the waste of Electrical and Electronic Equipment (WEEE) directive. The (WEEE) directive specifies ten categories and a voltage range which is up to 1.000 volts AC or 1.500volts DC. The developed framework came for the implementation of Eco-design principles that helps to take into account the adaption of the (WEEE) directive and the restriction of hazard substances (RoHS) used in electrical and electronic equipments. As a result of identify gaps and needs such as a lack of a comprehensive Eco-design framework and the need to integrate it to the normal business operation. In this research the PDCA framework for Eco-design and WEEE directive will be discussed. The framework will encompass all of the Eco-design¿s implementation and integration factors and activities such as WEEE and RoHS directives, Eco-design management, Environmental legislations, Eco-design tools and considerations. The literature review covers the topic of Eco-design¿s related issues, and WEEE and RoHS directives rules. Based on comprehensive questionnaire survey of Eco-design, WEEE and RoHS issues and activities among a sample of environmentally aware companies, statistical analysis is carried out using SPSS software. Then the findings of the survey triangulated with the findings of the literature review formed the basis of the design and implementation plan of the proposed framework

Scientifiques, gouvernements, entreprises et consommateurs s’entendent aujourd’hui pour dire que le système naturel est déréglé, que l’activité industrielle en est la cause principale. L’éco-conception est une manière de concevoir des biens ou des services en diminuant leurs impacts sur l’environnement et la société. De plus en plus présente dans les grandes entreprises où, associée à une gestion intégrée de l’environnement, elle procure des bénéfices non négligeables et une image de marque, l’éco-conception a beaucoup de difficultés à s’implanter dans les petites et moyennes entreprises. Dans ce travail, nous avons cherché à comprendre les raisons de ces difficultés. Deux approches ont été utilisées, l’une basée sur une analyse documentaire des rapports de RSE de dix entreprises, grandes et petites, de différents secteurs d’activité, qui nous a permis de fixer le cadre et le formalisme de la démarche de recherche, l’autre sur le principe d’entretiens semi-dirigés à partir de questions ciblées. Après une présentation générale de ce qu’est l’éco-conception et quelle en est la problématique appliquée aux PME (chapitre 2), nous précisons le cadre méthodologique de la recherche (chapitre 3) et exposons ses résultats (chapitre 4). Nous montrons que les freins à l’adoption de l’éco-conception dans les PME sont multiples et complexes, tant la diversité de ces entreprises est grande et difficile à synthétiser. En soulignant les freins, les leviers, les risques et les opportunités liés à l’intégration des principes de développement durable dans ces entreprises, nous faisons un portrait global de la situation actuelle et des difficultés rencontrées par ces PME pour adhérer à ces principes. / Scientists, governments, businesses and consumers agree that the natural system is deregulated, and that the industrial activity is the main cause. Eco-design is a way to design products or services by reducing their impacts on environment and society. This approach to design is increasingly present in large corporations which, combined with an integrated environmental management system, provides significant profits and brand image. Conversely, eco-design is barely implanted in small and medium-sized enterprises (SMEs). Through this research, we have tried to understand the reasons of these difficulties. Two approaches have been used. One is based on a document review of corporate social responsability (CSR) reports of ten, large and small, companies from different industrial sectors. This has enabled us to establish the framework and the form of the research approach. The second approach is based on semi-directed interviews with a set of prepared specific questions. After an overview describing eco-design and its problematic applied to SMEs (Chapter 2), we develop the methodological framework of this research (Chapter 3) and present its results (Chapter 4). We show that the barriers to adoption of eco-design within SMEs are multiple and complex, so much the diversity of these companies is vast and difficult to synthesize. By highlighting the barriers, the drivers, the risks and the opportunities related to integrating sustainable development principles in these organizations, we provide an overview of the current situation and challenges faced by SMEs when seeking to adhere to these principles.

Au cours de cette thèse, les prévisions de la méthodologie d’Analyse de Cycle de Vie (ACV) sont améliorées, via l’exergie, pour l’analyse et l’éco-conception des procédés. Nous mettons l’accent sur le potentiel de l’analyse exergétique et de la Consommation d’Exergie Cumulée (CExC) dans l’évaluation du critère d’épuisement, de productivité et de recyclabilité des ressources naturelles. Dans ce cadre, les transferts de pollutions et les impacts environnementaux d’un système de traitement des eaux résiduaires (STEP) ont été analysés en relation avec l’exergie consommée (CExC) et de l’exergie détruite (étude a priori). L’étude montre que la décision est différente lorsque l’indicateur d’épuisement des ressources naturelles est basé sur la méthode CExC de celle basée sur la méthode CML. L’amélioration de l’éco-efficacité d’une STEP implique un recyclage des boues en agriculture. La stabilisation des boues par digestion anaérobie réduit le volume des boues et ainsi l’impact du transport en comparaison avec la stabilisation à la chaux. Toutefois, elle réduit le potentiel fertilisant des boues, d’une part, et augmente la consommation d’énergie et l’impact du réchauffement climatique à cause du traitement des retours en tête d’autre part. Bien que la valorisation du biogaz en cogénération réduise la dépendance énergétique de la STEP et améliore son éco-efficacité globale en comparaison avec le chaulage, elle n’offre pas la possibilité à un séchage des boues. Le séchage des boues constitue l’une des recommandations des agriculteurs, bien qu’il n’améliore pas le l’éco-efficacité globale de la STEP, en augmentant l’épuisement et l’exergie détruite des ressources brutes et du biogaz / The focus of the work has been to improve the predictions of Life Cycle Assessment (LCA) via exergy for processes analysis and eco-design. The potential of the exergetic analysis and Cumulative Exergy Consumption (CExC) in estimating the criterion of depletion, productivity and recyclability of natural resources has been investigated. In this context, the transfer of pollutants and the environmental impacts of a wastewater treatment system (WWTP) have been analyzed in relation with the consumed exergy (CExC) and the destroyed exergy. The study shows that decision is different if the indicator of depletion of natural resources is based on the method of CExC or on the CML method. The improvement of the overall eco-efficiency of a WWTP involves a recycling of sludge in agriculture. Stabilization of sludge by anaerobic digestion reduces the volume of sludge and consequently the impact of transport in comparison with the stabilization with lime. However, on one hand, it reduces the fertilizer potential of sludge. On the other hand it increases energy consumption and the impact of the global warming because of the treatment of digested sludge supernatant recycled to the WWTP. Although the recovery of biogas by cogeneration reduces the energy dependency of the WWTP and improves its overall eco-efficiency in comparison with the liming scenario, it does not provide the possibility for sludge drying. Drying the sludge is one of the recommendations of farmers, although it does not improve the overall eco-effectiveness of the WWTP, and increases the depletion and the destroyed exergy of raw resources and biogas

Ce travail a pour objectif le développement d’une méthodologie de conception de procédés éco-efficaces, avec prise en compte simultanée de considérations écologiques et économiques lors de la phase de conception préliminaire de procédés chimiques. L’aspect environnemental est quantifié à travers l’utilisation d’un ensemble d’indicateurs selon les lignes directrices de concepts de développement durable. Le cadre conceptuel est basé sur une modélisation du procédé et de l’unité de production d’utilités, car l’impact environnemental d’un procédé est lié non seulement aux effluents directs du procédé, mais également à la consommation énergétique, l’effet du recyclage, de la conversion des matières premières … Dans ce but, le logiciel d’aide à la décision ARIANETM dédié à la gestion des utilités des unités de production (vapeur, électricité, eau …) et des effluents (CO2, SO2, NOx, etc..) a été couplé au modèle d’un procédé pour déterminer les besoins en énergies primaires et quantifier les émissions polluantes. Ces modèles ont ensuite été intégrés au sein d’une boucle d’optimisation multiobjectif, basée sur une variante d’un algorithme génétique multiobjectif de type NSGA-II (Non Sorted Genetic Algorithm). Le compromis entre les objectifs économiques et écologiques est illustré à travers la génération de fronts de Pareto. La sélection des meilleures solutions parmi cet ensemble est effectuée par utilisation de techniques d’analyse multicritère. L’exemple test bien connu du procédé de production de benzène par hydrodésalkylation du toluène (HDA) est revisité ici dans un mode multiobjectif pour illustrer l’utilité de l’approche pour trouver des solutions de conception économiques et écologiques. / This study aims at the development of a design methodology for eco-efficient processes, meaning that ecological and economic considerations are taken into account simultaneously at the preliminary design phase of chemical processes. The environmental aspect is quantified by using of a set of indicators following the guidelines of sustainability concepts. The design framework is based on a modelling approach considering both process and utility production units, since the environmental impact of a chemical process not only contains the material involved in the process but also the energy consumption, the effect of flow recycle, material conversion and so on... For this purpose, a decision support tool dedicated to the management of plant utilities (steam, electricity, water...) and pollutants (CO2, SO2, NOx, etc..), (ARIANETM package) was coupled to process modelling and used here both to compute the primary energy requirements of the process and to quantify its pollutant emissions. Both models were thus integrated in an outer multiobjective optimization loop, based on a variant of the so-called NSGA-II (Non Sorted Genetic Algorithm) multiobjective genetic algorithm. The trade-off between economic and environmental objectives is illustrated through the generation of Pareto fronts. The selection of the best design alternatives is performed through the use of multicriteria analysis. The well-known benchmark process for hydrodealkylation (HDA) of toluene to produce benzene, revisited here in a multi-objective mode, is used to illustrate the usefulness of the approach in finding environmentally friendly and cost-effective designs.
