Sustainable development is an eternal topic and the enterprise’ sustainability provides the answer. Furthermore, emerging market’s sustainable development is frequently mentioned recently due to the serious pollution and waste due to the blind pursuit of higher GDP (Colm, 2012). This paper aims to find out the drivers and barriers of green supply chain management (GSCM) implementation; and figure out how to strengthen the relationship between green purchasing (GP) and GSCM based on the single-case study of Guitang Group. Combining the qualitative and quantitative method, we try to explore and describe the influence on GSCM development caused by the specific background of China. Based on the suggestions of how to strengthen the relationships between GP and GSCM, it will be more efficient for us to find a suitable way for manufacturing industrial companies in China to achieve the path from green purchasing to green supply chain management.

The development and application of inventory models for deteriorating items is one of the main concerns of the experts in the domain, since the number and variety of deteriorating products are dramatically increasing. One of the major gaps in the deteriorating inventories literature is that researchers have not paid enough attention to two important features in their models: i) Considering stochastic conditions; especially stochastic lead time is almost overlooked since makes the mathematical challenges complicated, ii) designing innovative inventory policies by taking into account the environmental issues and particularly the CO2 emission as a new objective in a multi-objective framework that is quite new. In this thesis, we study replenishment policy for deteriorating products under stochastic conditions in form of three different problem areas. In the first one, we develop a continuous (r,Q) inventory model for a retailer that offers a deteriorating product by considering infinite planning horizon, stochastic lead time, constant demand rate and backordered shortages. For modeling the deterioration process, a non-linear holding cost is defined. Taking into consideration the stochastic lead time as well as a non-linear holding cost makes the mathematical model more complex. We therefore customize the proposed model for a uniform distribution function that could be tractable to solve optimally by an exact approach. In second problem, we study the strategy of pooling lead time risks by splitting replenishment orders among multiple suppliers simultaneously for a retailer that sells a deteriorating product. Finally, in the last problem, we consider inventory and transportation costs, as well as the environmental impacts in a centralized supply chain by taking into account uncertain demand and partial backordered shortages. In order to deal with demand uncertainty, a two stage stochastic programming approach is taken. Then, by considering transportation vehicles capacity, we develop a mixed integer mathematical model. In this way, the best transportation vehicles and replenishment policy are determined by finding a balance between financial and environmental criteria. A numerical example from the real world is also presented to show the applicability and effectiveness of the proposed model.

En ökad textilkonsumtion har lett fram till en problematik kring miljöpåverkan på grund av den ökade mängden använda textilier som ska hanteras efter produkternas död. För att ta till vara på de dyrbara resurser som har använts för att skapa textila produkter, har intresset för återvinning av textila fibrer ökat. Forskningen inom återvinning av bomullsfibrer har däremot inte kommit tillräckligt långt för att produktion av återvunna fibrer av hög kvalité ska kunna göras storskalig. Detta speciellt eftersom problem med exempelvis blandfibrer och separerbarhet försvårar arbetet. Det finns förändringar som kan göras av modeföretag i produktutvecklingsfasen redan idag, vilka kan underlätta återvinningsprocessen och syftar till att skapa ett slutet system i framtiden. Därför finns det ett behov av att identifiera vilka interna problem som kan hindra en produktutveckling av återvinningsbara plagg, samt vilka förändringar som kan behöva ske av ett modeföretags externa relationer för att kunna införa denna produktutveckling. Genom djupintervjuer som utfördes med sju anställda vid fallföretaget Lindexs design- och inköpsavdelning har det klargjorts hur företagets nuvarande arbetsprocesser ser ut, samt vilka hinder som finns och vilka förändringar som behövs inom produktutvecklingen för att underlätta återvinningen. Detta gjordes genom att olika produktgrupper studerades utifrån tre utvalda scenarion som alla skulle underlätta återvinningen av plaggen. Resultatet visade att det finns tillräckliga resurser för att många anpassningar skulle kunna ske redan idag, dock inte i någon större utsträckning på grund av begränsningar inom designen. Ett stort hinder är det bristfälliga kommunikationsflödet, internt inom fallföretaget och externt mellan huvudkontor och leverantörer. Viktiga resurser som har identifierats och som underlättar införandet av förändringar är däremot en drivkraftig leverantörsbas och de långsiktiga relationerna till leverantörerna. Ett begränsat synfält av företagets nätverk har dessutom identifierats hos design- och inköpsavdelningen vid fallföretaget. Slutsatsen är därför att detta skulle behöva vidgas för att implementera förändringar. Även kommunikationsflödet bör nyttjas fullt ut för att de anställda ska kunna arbeta mot uppsatta mål, vilket ställer krav på ledningen att arbeta fram riktlinjer för hur en produktutveckling för återvinningsbara plagg ska genomföras. För att vissa förändringar i riktning mot återvinningsbara plagg ska kunna genomföras, krävs dessutom att modeföretag samarbetar för att driva frågan.Trots att återvinningsbara plagg är möjliga att producera i dagsläget, krävs fortfarande vidare studier angående hur detta är tekniskt möjligt i storskalig produktion, samt hur kvalitetsproblemen förknippade med återvunna fibrer ska hanteras. / An increase in the consumption of textiles has created a greater environmental impact due to the increased amount of textiles that need to be processed when the product reaches end of life. To ensure the continued use of the precious resources used to create textiles the interest in fiber recycling has increased. The research in recycling cotton fibers is however limited and does not yet allow for production of high quality fibers in a large scale, especially due to the problem with separating material with more than one fiber type. There are changes that fashion companies can make today in the product development stage that will facilitate the recycling process and lead to the implementation of a closed loop system in the future. There is a need to identify the internal problems that can prevent development of recyclable clothing, as well as the changes necessary in a fashion company's external relationships to implement this type of product development. In depth interviews were conducted with seven employees working in the design and purchasing department of the case study Lindex. Through the interviews the employees clarified how the design and purchasing processes in the company are now as well as what barriers and changes may be necessary for product development of recyclable clothing. Three different product groups were studied through scenarios that would facilitate recycling of clothing. The results of the study shows that the company has the resources to implement many of these changes today, however not to a large extent throughout the collections due to design limitations. A large barrier is the inadequate communications flow internally in the case company and externally between the head office and suppliers. Important resources that have been identified in the study that will ease the implementation of changes are however a driven supplier network and the long term relationships to these suppliers. A limited view of the company's network has also been identified within the design and purchasing department of the case company. In conclusion this would need to be widened to allow for implementation of changes. Even the communications flow should be fully utilised to allow the employees to work towards the companys goals, which places demands on management to define guidelines for product development of recyclable clothing. To be able to implement certain changes that would allow for production of recyclable products, a collaboration between fashion companies would be required. Despite the fact that recyclable garments are possible to produce today, further research is needed to develop the technology to produce garments from recycled fibers in a large scale, as well as to address the quality problems associated with recycled fibers. The language of this report is Swedish.

Áreas de impacto aparentemente não financeiro vêm assumindo papel de grande relevância no mundo dos negócios. E, o grande desafio consiste em encontrar equilíbrio entre baixo custo e um elevado padrão de qualidade, considerando aspectos de desenvolvimento sustentável e atendendo às reivindicações da sociedade. Neste cenário, há que se considerar o aumento no consumo e conseqüente descarte de embalagens e resíduos dos mais variados tipos. Assim, áreas como a logística reversa pós-consumo vem ganhando destaque. As garrafas PET são um exemplo de produtos que podem ser reciclados e reinseridos na cadeia produtiva. Mas, para isso é necessário o envolvimento de todos os atores que participam desta cadeia de produção, consumo, descarte e reciclagem das embalagens. Da mesma forma, a responsabilização dos fornecedores pelo recolhimento de suas embalagens, a substituição de materiais, bem como um maior reaproveitamento dos resíduos, contemplam práticas de logística reversa e, de forma mais abrangente, envolvem aspectos da Gestão Sustentável da Cadeia de Suprimentos. Assim, o objetivo principal desta pesquisa consiste em investigar limitações e oportunidades presentes nas práticas de logística reversa pós-consumo de duas indústrias de diferentes setores. Para isso foram escolhidos dois segmentos: (i) produção de carrocerias e ônibus – empresa Bus S.A. e (ii) indústria de bebidas – empresa Soft Drink S.A. O intuito é estudar duas situações contrastantes sob a perspectiva da cadeia produtiva. No primeiro caso, o foco são materiais e embalagens, especialmente as de produtos químicos, utilizados pela empresa e que retornam, ou deveriam retornar, aos seus fornecedores. No segundo caso, a pesquisa aborda o processo de produção, consumo, descarte e reciclagem de embalagens PET, ou seja, o foco recai principalmente sobre as práticas relacionadas ao pós-consumo externo. O método utilizado foi o estudo de caso, com realização de entrevistas e os dados foram analisados através da análise de conteúdo e triangulação. Os principais resultados apontam que as práticas de logística reversa são amplamente influenciadas pela articulação dos atores das cadeias produtivas e, principalmente, pelas políticas públicas de incentivo e suporte ao descarte correto, reciclagem, produção de resina reciclada, coleta seletiva e conscientização do consumidor. / Areas of impact apparently non financial have been taking a role of extremely prominence in the world of business. The great challenge consists of finding a balance between a low cost and a high standard of quality, considering aspects of sustainable development and complying with the society‟s claims. In this scenery one has to consider the increase number in consume and therefore waste of packaging and residues of the most diverse types. Thus, fields as the reverse logistic post-consume has been gaining distinction. Discarded bottles are ways of example of products which can be recycled and reinserted in the productive chain. But, for such it is necessary involvement of every agent who take part of this productive chain, consume, discard and packaging recycling. In the same way, the responsibility of suppliers by packaging collecting, materials replacement as well as a better reuse of its residues contemplate practices of reverse logistics and of a more comprehensive way that involve aspects of Sustainable Management of the Supply Chain. So, the main goal of this research consists of investigating restraints and opportunities in the practices of reverse post-consume of tow industries of different sectors. For such two segments were chosen: (i) production of coach body and coaches – company Bus S.A. e (ii) industry of beverages – company Soft Drink S.A. The aim is to study two contrasting situations under the productive chain perspective. In the first case, the focus on materials and packaging mainly of the chemical products used by the company and that return or should be returned to its suppliers. On the second case the research approach the production process, consumption, discard and discarded bottles‟ recycling, that is, the focus falls into mainly the practices related to external post-consumption. The method used was the case study, with interviews taking place and data were analyzed through the content and triangulation. The main results show that the reverse logistic practices are widely influenced by the productive chain agents‟ dispute and mainly by public policies of incentive and support to the right discard, recycling, production of recycled resin, selective collecting and consumer awareness.

The study examines how a select automobile company implement sustainablepractices in their supply chain management to achieve environmental sustainability.The focus of the study is on the two (2) most important aspects of the supply chainmanagement namely Supplier Selection and Product Design. Supplier selection isvital for 2 reasons; focal companies are increasingly being held account for theenvironmental impacts of their suppliers and more value is generated at the supplystage in the value chain. Product designs are vital because it helps reduce energyconsumption and emissions during the lifecycle (operational/use) of the vehicle.The study finds that the select automobile company has a robust procedure forsupplier selection & development using its Supplier code of conduct, SelfAssessment Questionnaires (SAQ) and a Sustainability Rating system for supplierselection and monitoring supplier compliance with environmental performancegoals.To achieve reduction in emissions from the company’s products in the use phase,the company has developed a range of products which focus on fuel efficiency,powertrains (engine) performance, renewable/alternative fuel sources andelectrified vehicles. These product designs are part of the company’sdecarbonization strategy to reduce emissions from its product use which accountsfor about 90% of the company’s carbon footprints (emissions). These products aredesigned with specific/set environmental goals/targets by working jointly with theScience Based Target Initiative (SBTi). An initiative (by WWF, CDP and WRI)which relies on the most recent climate science to help company achieve itsenvironmental goals while meeting its economic goals as well. The company’sdecarbonization strategy are directly linked to its supplier selection and productdesigns in order to achieve environmental sustainability.Overall, the study finds that the company’s practices are in line with existingliteratures on how to achieve environmental sustainability in Supply ChainManagement, for instance, the frameworks by Matthiavanan (2018) and Masoumi(2019) identified sustainable supplier selection & development, environmentalstandards, auditing suppliers, green/environmental purchasing, innovative productdesigns that reduce emissions & waste which are practices identified in the casecompany. Hence, the study reveals there is a strong link between theory and practicein the Case Company.This study has practical implications as insights provided can help other automobilecompanies address environmental sustainability challenges they face in theirsupplier selection process and product designs.

The manufacturing industry has exerted a tremendous impact on the natural environment. The aim of this thesis is to evaluate the consequences of shift from linear manufacturing system to circular manufacturing system in order to decouple the environmental burden of production and consumption process in relation to quantity of carbon footprint, cumulative energy demand, natural resource consumption, waste generated and recovered presently. In response to this, life cycle assessment (LCA) is used to quantify and compare the associated environmental impact of the current manufacturing system of both Linear manufacturing system and the circular manufacturing system. The thesis therefore asserts that circular manufacturing system (CMS) is more sustainable compared to linear manufacturing system (LMS) in relation to its reduction capacity of the prevailing environmental indicators most especially global threat of natural resources depletion and climate change confronting biodiversity. The result shown that CMS seems more sustainable compared to LMS in relation to the studied environmental indicators. Further to this, the emerging circular manufacturing system, its transitional shift, challenges, and its relationships with other manufacturing dynamics for consideration are also highlighted and discussed. It was concluded that these prominent challenges are caused by organizational management in relation to leadership and communication (OLC), has the highest impact value. Similarly, the consequential effect was seen on the level of implementation of government policy (GPI) and deployment of state of the art design, knowledge and technology (DTK) for the paradigm shift. So, it is suggested that OLC should be given due consideration.
