Worldwide, around 17% of food waste produced in high income countries is constituted of dairy products. In Sweden, Dairy Company A has been dealing with food waste production throughout all their sites. Although it already practices actions such regarding food waste minimization such as biogas generation and animal food, reduction and prevention practices are still an area of opportunity. The aim of this study is to explore alternatives for food waste prevention in Company A CSE dairy supply chain and generate recommendations that help the company achieve a more sustainable supply chain.  This study furthermore proposes a 5-step research methodology to identify food waste causes and drivers, including data gathering mainly through interviews and analysis based on proposed frameworks in relevant literature. It was found that activities related to systematic root cause identification and information storage and sharing play a key role in improving existing practices that aim to reduce and minimize food waste production from a supply planning perspective.  The research identified and recommended not only to raise awareness, which is key to reducing food waste, but to put into a broader context how decisions taken by any planner could be influencing the sustainability of the supply chain. This could be done through the adoption of process-driven mechanisms to share relevant information as well as food waste root cause identification. / Över hela världen utgörs cirka 17 % av matavfallet som produceras i höginkomstländer av mejeriprodukter. I Sverige har Mejeriföretag A sysslat med produktion av matavfall på alla sina anläggningar. Även om det redan tillämpar åtgärder som när det gäller minimering av matsvinn, såsom generering av biogas och djurfoder, är metoder för reduktion och förebyggande fortfarande ett område med möjligheter. Syftet med denna studie är att utforska alternativ för att förebygga matsvinn i Company A CSE-mejeriförsörjningskedjan och generera rekommendationer som hjälper företaget att uppnå en mer hållbar försörjningskedja.  Denna studie föreslår dessutom en 5-stegs forskningsmetodik för att identifiera orsaker och drivkrafter för matsvinn, inklusive datainsamling främst genom intervjuer och analyser baserade på föreslagna ramverk i relevant litteratur. Det visade sig att aktiviteter relaterade till systematisk rotorsaksidentifiering och informationslagring och -delning spelar en nyckelroll för att förbättra befintliga metoder som syftar till att minska och minimera produktionen av matavfall ur ett utbudsplaneringsperspektiv.  Forskningen identifierade och rekommenderade inte bara att öka medvetenheten, vilket är nyckeln till att minska matsvinnet, utan för att sätta in i ett bredare sammanhang hur beslut som fattas av alla planerare kan påverka leveranskedjans hållbarhet. Detta skulle kunna göras genom antagandet av processdrivna mekanismer för att dela relevant information samt identifiering av rotorsak för matavfall.

The concept Lean Production has nowadays become an accepted paradigm in several industries and it has become a fundamental part of manufacturing companies, as it seeks to reduce waste and deliver a high customer value. Lean Production is a technique that is a highly efficient manufacturing practice that helps organizations to carry on a competitive advantage. The concept works as a system of methods and measures which when combined have the potential to carry about a lean manufacturing. The objective of this research is to investigate how Strålfors Svenska Card can succeed in carrying out changes in their production in order to reduce waste, with reference to Lean Production. The study starts with a brief historical review about lean production, which is followed by a theoretical framework with useful concepts to adapt. The theoretical frameworks used in this research are: Lean House, “4P” Model, Lead the Change, Culture, Processes and Performance Measurements. The main research question of this thesis is: What are the main barriers for a successful lean implementation in Strålfors Svenska AB? Subsequently, the main research question was broken down to four sub questions. These are: How developed and mature in the organization are process methods? How are performance measurements employed? Which role does standardization, such as availability of tools, have? Which role do soft aspects, such as culture and values, play in understanding concepts?  Strålfors Svenska Card has to build a good platform in order to success with their implementation of lean production. Moreover, it means that the organization has to focus on developing necessary critical factors that are in the guideline with lean production. The researchers has used observations, interviews, surveys and value stream mapping in order to collect necessary data.

Nos últimos anos, as empresas de construção implementaram ferramentas e práticas para alcançar um nível de qualidade e padronização, como desejado por seus clientes, tais como a ISO 9001 e o sistema brasileiro PBQP-H. Em alguns casos, as empresas de construção implementam sistemas isolados para gerir a produção, qualidade, segurança e meio ambiente. A integração entre a produção e outros sistemas de gestão é benéfico para alcançar melhorias na construção. No entanto, não existem trabalhos de pesquisa que descrevem este tipo de aplicação em pequenas empresas de construção, que constituem a maioria das empresas. Este trabalho estuda a implementação de um sistema de gestão completo integrado numa empresa de construção, visando reduzir desperdícios no processo produtivo. O trabalho inclui o diagnóstico de uma empresa antes e depois da implementação do processo integrado, bem como a identificação de resultados Desenvolveu-se através da observação de três canteiros de obra de porte semelhante, na cidade de Bento Gonçalves, RS, Brasil. No processo de investigação foram implementadas as ferramentas de planejamento e controle em todos os sistemas de gestão em curto, médio e longo prazo. Com os resultados pode-se concluir que há viabilidade de implementar este sistema em empresas de pequeno porte, com redução de resíduos no processo de produção. / Construction firms look for improvements in its procedures and try to surpass the general level of building industry. In the last years building firms implemented tools and practices to achieve the standardization and quality level as desired by its clients, such as the systems ISO 9000 and Brazilian? PBQP-H. In some cases, construction companies implement isolated systems to manage production, quality, safety, and environment. The integration between production and other management system is beneficial for achieving improvements in construction. However, there are not research papers that describe this kind of application in small construction companies, which constitute the majority of companies. This work studies the implementation of a full-integrated management system in a construction company, aiming to reduce wastes in the production process. The work includes the diagnosis of a company before and after the implementation of the integrated process, and the identification of outcomes. It developed through observation of three sites of similar size, in the city of Bento Gonçalves, RS, Brazil. On research process it were implemented tools on planning and control to all management systems to short, medium, and large terms. Results may conclude that there is viability to implement this system in small building companies, with waste reduction on the production process.

At the retail level, 25% of sellable food is wasted, and perishable foods account for 72% of food waste in the United States. The purpose of this qualitative phenomenological study was to explore the food waste reduction strategies used by supermarket perishable food department managers, which are covered under the Good Samaritan Food Donation Acts (state and federal). The participant population was comprised of 17 managers who are responsible for perishable foods departments (bakery, deli, meat, dairy, and produce) at local, regional, and national supermarkets in Midland, Michigan. Goal systems theory served as the conceptual framework lens for which the findings of this study are viewed. Data collected centered around long interviews and publicly available company documents. Interviews and field notes, including member checking, were transcribed and analyzed using NVivo software. Using methodological triangulation of these data sources, 3 themes emerged from the data analysis: the knowledge level of participants relative to the Good Samaritan Food Donation Act, factors that influence food waste and management strategy, and existing food waste reduction strategies. Most front-line managers are not aware of the Good Samaritan Food Donation Act. Factors that influence food waste include sell-by dates, personal bias, and food handling regulations. Existing food waste reduction strategies include donations, price reductions, stock rotation, and in-store repurposing. Positive social change may result from the results of this study if food waste can be further reduced or more food redirected to the needy. The study findings may be useful to supermarket managers as they consider the protection at the state and federal levels that the Good Samaritan Food Donation Act offers.

The diploma thesis deals with the concept of circular economy (hereinafter CE) and its application in several Czech and one multinational company. On these specific examples of companies, the work shows how circularity is achieved, with all the essentials of this fact, what support for the concept is offered in the Czech Republic and, last but not least, what obstacles and problems the companies face. Along with this practical experience, opinions by theoretical experts who deal with the issue in their profession are further examined. The aim of the work was to map the matter of use of secondary raw materials and other principles of CE in both practical and theoretical spheres of knowledge, and where possible, to compare these two views. Furthermore, the work focuses on the benefits of real use of the principles of CE in the Czech conditions from an environmental point of view. In its theoretical part, it first addresses the issue of waste in general, especially from the perspective of a global problem. It presents the development, current situation and forecast of the size of waste generation, including its impacts. Furthermore, it has introduced the concept of CE, its various concepts and definitions, together with the main principles. Subsequently, it presents the real adoption of the concept by...

The Circular Economy (CE) represents a transformative approach to sustainable development, aiming to replace the traditional linear "take-make-waste" model with a regenerative system that minimizes waste through the continual use of resources. This thesis provides an up-to-date examination of the adoption of CE principles within a selection of Swedish companies, exploring how these principles are integrated into their business models and the challenges and opportunities that arise from their implementation. Through a comprehensive analysis, including literature reviews, document analysis, comparative analysis, and thematic analysis, this study provides a detailed insight into the operationalization of CE in Sweden and a hypothetical case study scenario with recommendation on implementing CE practices. Companies such as IKEA and H&M are highlighted for their robust CE practices. The findings suggest a positive trend toward sustainability, driven by a combination of regulatory support and strong corporate commitment to environmental stewardship, although challenges related to operational and regulatory constraints persist. This thesis contributes to the broader discourse on sustainable economic practices by outlining actionable strategies for enhancing CE adoption across industries.

The aim of this study was to explore consumers’ descriptions of sustainable food consumption. The concept of sustainability can be difficult to grasp, but is often defined in terms of three pillars; environment, society and economy. Prior research of sustainable food consumption have often focused on one of the pillars rather than all of them together in relation to consumers understandings of sustainable food consumption. Notwithstanding, previous research have mentioned that in order to fully comprehend sustainability it is essential to take all of the three pillars into consideration. Therefore, this study acknowledged this gap, as it focused on the three pillars of sustainability as a base, and further connected the three pillars to the four food concepts; organic, Fairtrade, sustainable diets and waste, in order to fully understand consumers descriptions of sustainable food consumption. The study was conducted using a qualitative approach, and the data was collected through semi-structured interviews with a sample of students and employees at Linnaeus University in Sweden. The interviewees gave varied and interesting answers, which later were analyzed in comparison to the theory on the subject. With the answers from the interviews it was concluded that environmental and social sustainability were prioritized to economic sustainability among participants. As the participants’ descriptions of sustainable food consumption was varied, and all of the four concepts in relation to three pillars were analyzed, a framework was developed in order to clarify how the consumers describe sustainable food consumption. The study also presents a number of implications for further research as well as managerial implications.  Keywords Sustainable food consumption, consumers description, three pillars of sustainability, economic sustainability, environmental sustainability, social sustainability, organic, Fairtrade, sustainable diets, vegetarian, locally produced, waste reduction, food waste

Purpose The purpose of this thesis is to set up a closed-loop supply chain model for B2C online subscription box retailers and to develop a business case evaluating the model’s sustainability. Method This explorative thesis has an abductive research approach. Multiple-case studies are conducted and data from four cases and an expert are collected by conducting interviews. The research contains both qualitative and quantitative data. Findings A closed-loop SC model is created with regards to transport packaging. The model suggests that once the package is received by the consumer it can be returned in an empty state. After being cleaned it should be reused by the 3PL. The model’s sustainability is evaluated by developing a business case. Sustainable performance measures with regards to economic, social and environmental practice are assembled. The model enhances general social performance and environmental performance. Economic performance is mostly positively influenced. Options for cost savings in order to improve the economic performance of the model are suggested by the researchers. Practical implications The work provides businesses within the online B2C subscription box retail with a model for a possible closed-loop supply chain with regards to transport packaging. The business case for sustainability can be applied as a guideline to evaluate the model or similar ones. Researchers give suggestions on adapting packaging to enhance economic performance. Societal implications This thesis points out possible environmental and social benefits that may be achieved by a closedloop supply chain model. Besides waste and emission reduction, social performance such as employee motivation is positively influenced. Theoretical implications The thesis provides a model developed from theory and empirical data. The model does not only have practical implementations but also complements theory where a gap has earlier been identified. Through the business case for sustainability researchers contribute to theory since literature is scarce.
