Electric motors are one of the biggest consumers of electricity in the world with a consumption of almost 45 % and it is predicted to increase. Since electric motors play an important role today and in the future, it is important that businesses take their responsibility to make them as sustainable as they can possibly be. Today’s product development models are often based on the idea that the customer buys the product and is responsible for the products use phase. This results in the manufacturer focusing on getting a competitive price for the customer by reducing the cost for manufacturing and delivery, which often is negative for the customer. The latter phases, use and end-of-life, are often the greatest contributors of costs and environmental impact. One way for businesses to take their responsibility is to have an environmental focus throughout their products life cycles, i.e., to apply a circular business model. This primarily means to focus on the main principles of circular economy: to reduce, reuse and recycle. ABB is a company in the electric motor and drive industry with ambitious commitments for 2030 which includes to have at least 80 % of their products and solutions covered by a circularity approach and achieve carbon neutrality across their own operations. This Master thesis studies the environmental impact of an ABB synchronous medium voltage motor and drive during their life cycle. This thesis also studies how a circular business model can affect the environmental impact the motor contribute with today. Assessing the environmental impact was done with a life cycle perspective in accordance to ISO 14044, using the world’s most used tool for these kinds of analyses, SimaPro. The results of the assessment showed that the total climate impact during the whole life cycle of the motor and drive is 4.38•106 kg CO2 eq. The use phase of the motor and drive was the biggest contributor, with almost 99 % of total climate impact. The electricity used in this phase and the long lifetime of these machines, in this case 20 years, contributes to the great impact. Important environmental impact categories identified from studying the motor and drive during their lifecycles are ionizing radiation, human toxicity (both non-cancer effects and cancer effects) and freshwater ecotoxicity. The results also showed that by only looking at the contribution of the components of the motor, the climate impact is 7.35•104 kg CO2 eq. A total of 43 % of the emissions comes from the stator and 30 % from the rotor. For the drive the total impact is in total 6.83•104 kg CO2 eq. The biggest contributor is the semiconductor, with 50 % of the total impact of the machine followed by the housing with 21 %. Answering research question two, regarding the circular business model, was done by interviewing key players at ABB and people with knowledge in the area as well by studying literature. Potential measures for a circular business model were for example increasing the efficiency of the motor, designing for refurbishment and recycling, partnerships and changing the motor application after use. Increased efficiency of the motor was identified as a very impactful measure since it can affect the use phase, which is the biggest contributor of climate impact. The identified measures impact the material and energy flows in different ways, most of them prevent extraction of new raw material. This study can be used for an indication of where the environmental hotspots are for a MV electric motor and drive. It can be concluded that a circular business model could bring benefits on material and energy flows such as reduced energy use in the use phase, decreased use of raw material in production and reduced use of fuel for transportation.

[pt] A transição para uma economia circular (EC) requer modelos multidimensionais para a definição de objetivos e metas de circularidade em diferentes horizontes temporais, prazos, diretrizes circulares setoriais, políticas públicas nacionais e regionais, entre outros. Visando fornecer estruturas consistentes para decisões de negócios baseadas em evidências, com implicações para os níveis meso e macro de CE, o objetivo desta dissertação é propor um modelo de mensuração estratégica para monitorar e avaliar o desempenho da circularidade no nível micro, integrando GMA e dois métodos multicritério de tomada de decisão. Os principais resultados deste estudo envolvem: (i) uma matriz morfológica genérica composta por oito parâmetros e seus possíveis estados para definir e representar visualmente possíveis cenários de transição de CE para uma determinada organização que pretende evoluir através de transições de CE; (ii) o uso potencial de uma abordagem metodológica híbrida (que combina GMA com dois métodos MCDM) para selecionar os indicadores C mais relevantes para cada estratégia-R pode ser destacado; (iii) uma lista inicial de 58 C-indicadores e métricas associadas a dez estratégias-R e um conjunto de 38 C-indicadores selecionados por meio da adoção do método híbrido AHP-TOPSIS; (iv) definição de dez indicadores de circularidade compostos associados às estratégias R, bem como um Índice de Performance de Circularidade (IPC) geral, e um procedimento passo a passo para calculá-los em diferentes cenários de transição de CE. De uma perspectiva de transição circular, os resultados destacam implicações práticas para organizações e cadeias de valor, uma vez que o modelo foi concebido para ser aplicado em diferentes contextos de negócio, especialmente em organizações que irão definir seus objetivos de circularidade e respectivas agendas relativas à transição para uma economia circular. / [en] The concept of a circular economy (CE) transition requires multi-level frameworks regarding the definition of goals and targets for different time horizons, desired change timeframes, sectoral circularity guidelines, and national and regional public policies, among other factors. Aiming to provide consistent frameworks for evidence-based business decisions with implications for the meso and macro levels of CE, the objective of this dissertation is to propose a strategic measurement model to monitoring and evaluating the circularity performance at the micro level by integrating GMA and two multicriteria decision-making methods. The main findings of this study are: (i) a generic morphological matrix comprising eight parameters and their possible states to define and visually represent possible CE transition scenarios for a given organization that aims to evolve through CE transitions; (ii) the potential use of a hybrid methodological approach (that combines GMA with two MCDM methods) for selecting the most relevant C-indicators for each R-strategy could be highlighted; (iii) an initial list of 58 C-indicators and metrics associated to ten R-strategies and a set of 38 selected C-indicators by adopting the hybrid AHP-TOPSIS method; (iv) definition of ten composite C-indicators associated with the R-strategies, as well as an overall Circularity Performance Index (CPI), and a step-by-step procedure to calculate them in different CE transition scenarios. From a CE transition perspective, the results highlighted practical implications for organizations and value chains, once the proposed model is designed to be applied in different business contexts, especially in those organizations that will define their circularity targets and respective agendas concerning CE transitions.

Det finns förbättringspotential för att öka den cirkulära ekonomin i Sverige, som idag är 3,4 procent. Återbruk av byggmaterial i byggbranschen är en åtgärd, som genererar till en cirkulär förbättring. I uppsatsen belyses utmaningar och möjligheter associerade med återbruk av byggmaterial, som förekommer hos aktörer längs försörjningskedjan. En generell tanke som ofta förekommer är att återbrukat byggmaterial genererar till ökade kostnader, vilket det i uppsatsen påvisas åtskilda åsikter kring. Vidare studeras det som krävs för att lyckas implementera en cirkulär ekonomi i byggbranschen genom affärsmodeller och strategier. Genom att lyckas implementera en cirkulär ekonomi och utveckla expertis inom området, påvisar teori att även konkurrensfördelar kan frambringas. / There is potential for improvement to increase the circular economy in Sweden, which today is 3.4 percent. Reuse of building materials in the construction industry is one action, which generates a circular improvement. The study highlights challenges and opportunities associated with the reuse of building materials faced by different actors along the supply chain. A common understanding is that reused building materials generate increased costs, which the study demonstrates separate opinions about. Furthermore, the requirements to succeed in implementing a circular economy in the construction industry are studied together with business models and strategies for implementation. By succeeding in implementing a circular economy and developing expertise in the field, theory shows that competitive advantages can be generated.

One of the main polluting industries in the world with high environmental impact is the construction industry which also generates a huge amount of waste. To overcome the seburdens, we need to reduce the impacts through new solutions, technologies and by injecting circular economy concept into the industry. Construction and building material industry are responsible for nearly 11% of all GHG emissions and the usage of residential/commercial buildings is contributing to 28% of all GHG emissions globally. the construction industry is also responsible for 35% of the total wastes in the European Union. Both linear economy and emissions of the construction sector are becoming more important in recent years that led to the development of many standards, frameworks and innovations. Reporting environmental burdens of the construction elements, products and construction works or construction projects is one of the ways for emissions accounting. Therefore, a report on environmental impacts of goods or services is called environmental product claims which can be based on a single criterion (like CO2 emission or % of recycled content) or based on a complete LCA study with multiple impacts. These reports have been classified by ISO 14020 series in three types, Type I (third-party certified label), Type II (self-declared claims) and Type III (the third party verified declaration based on LCA study). The third type is known as Environmental Product Declaration (EPD). To make the LCA results in EPD:s comparable, Product Category Rules (PCR) are developed. The regulations for the construction materials are defined in EN 15804 so the declarations of the building materials and construction works according to these regulations are compliant with EN 15804. Another framework for environmental declarations called, Product Environmental Footprint (PEF) is developed in Europe. Besides Business to Business declarations that are the target group for EN 15804, PEF also includes environmental labelling (type I) with consumers as the target group. The PCR:s from the updated version of EN15804:2012+A2:2019 can be regarded as the parallel methodology specification for the construction materials in the PEF system. Other product groups' rules and specifications are based on the PEF guidance document. The overall aims of this study are to compare the EN 15804 and PEF formulas concentrating on credits at the end of life and after the end of life stage and to reduce the subjectivity of two variables, energy margin, and recycling rate in the assessment of recycling alternatives after the end-of-life stage. Calculated credits can be included differently in the environmental declarations depending on the methodological approach. PEF includes the End-of-Life (EoL) credits into the Life Cycle Assessment (LCA) study and adds them to the product's performance results, while EN 15804 mandates to report the credits from recycling/recovery separately as supplementary information to the products environmental performance. To compare the credits that are calculated according to PEF and EN 15804, a separate indicator is virtually defined for PEF in order to calculate all the credits separately and compare the results with EN 15804 Module Dresults to give the reader an overview of the most beneficial uses of the construction waste according to PEF and EN 15804. Reducing subjectivity of choosing recycling rate has been addressed by developing more transparent and less subjective tool by integrating and using DGNB (German Sustainable Building Council) and BRE (center for building research in the UK) methods. For energy margin, this has been done by integrating energy margin calculation tool by CDM (Clean Development Mechanism, United Nations) and find the contribution of different materials to the environmental benefits in and after the end of life stage of the building lifecycle. However, the DGNB and BRE methods require further development, since they are not originally developed for LCA studies and just used as the only current options available in order to make recyclability assessment methods compatible with LCA studies. Other methods, specifically for LCA, can also be developed in the future. Based on an inventory of the components and materials used in a real building, the most environmental benefits (credits) from downstream recycling/recovery considering all materials are generated for the wooden products when using the EN 15804 formula, while aluminium is in the second place. On the other hand, aluminium is in the first place and wood is second using the PEF formula. Aluminium has by far the most benefits (credits) considering the credits per kg of each material, due to the huge recycling potential that aluminium has and will replace primary aluminium in the future. Unlike PEF, EN 15804 reports all credits separately outside of the LCA system boundary. This is very beneficial since the correct verified LCA will not beaffected by the credits that are given based on current technologies when the end of life of the building components are between 40 to 120 years away from today. / En av de industrier i världen med högst miljöpåverkan är byggbranschen som också genererar en enorm mängd avfall. För att hantera detta måste vi minska effekterna genom nya lösningar, teknologier och genom att använda konceptet cirkulär ekonomi i byggbranschen. Bygg- och byggnadsmaterialindustrin är ansvarig för nästan 11% av alla växthusgasutsläpp och användningen av bostäder / kommersiella byggnader bidrar till 28% av allaväxthusgasutsläpp globalt. Byggbranschen ansvarar också för 35% av det totala avfallet i EU. Både linjär ekonomi och utsläpp från byggsektorn har blivit viktigare under de senaste åren vilket har lett till utveckling av många standarder, ramverk och innovationer. Att rapportera miljöbelastningar för byggelement, produkter och bygg- och anläggningsarbeten är ett av sätten för utsläppsredovisning. Därför kallas en rapport om miljöpåverkan av varor eller tjänster Miljömärkning som kan baseras på ett enda kriterium (som CO2-utsläpp eller procent av återvunnet innehåll) eller baserat på en fullständig LCAstudie med flera effekter. Dessa rapporter har klassificerats enligt ISO 14020-serien i tre typer, typ I (tredjepartscertifierad märkning), typ II (självdeklarerade påståenden) och typ III (tredjepart verifierad deklaration baserad på LCA-studie). Den tredje typen är känd som Miljövarudeklaration/Environmental Product Declaration (EPD). För att göra LCA-resultat i EPD:er jämförbara, utvecklas Product Category Rules (PCR) (Produktkategoriregler). Regler för byggnadsmaterialen definieras i EN 15804, så deklarationerna om byggnadsmaterial och byggnadsarbeten enligt dessa regler överensstämmer med EN 15804. Ett annat ramverk för miljödeklaration är ProductEnvironmental Footprint (PEF) som är utvecklad inom EU. Förutom Business to Businessdeklarationer som är målgruppen för EN 15804 inkluderar PEF också miljömärkning (typ I) med konsumenter som målgrupp. PCR:erna från den uppdaterade versionen av EN 15804:2012 + A2: 2019 kan betraktas som den parallella metodspecifikationen för byggmaterialen i PEF-systemet. Andra produktgruppers regler och specifikationer är baserade på PEFs vägledningsdokument. De övergripande syftena med denna studie är att jämföra formlerna EN 15804 och PEF som koncentrerar sig på krediter i slutet av livscykeln och att minska subjektiviteten för två variabler, energimarginal och återvinningsgrad vid bedömningen av återvinningsalternativ i slutet av livscykeln. Beräknade krediter kan inkluderas olika i miljödeklarationerna beroende på den valda metoden. PEF inkluderar slutet av livscykeln (EoL)-krediter i livscykelanalys (LCA) -studien och lägger dem till produktens resultat, medan EN 15804 kräver att krediterna från återvinning rapporteras separat som kompletterande information till produkternas miljöprestanda. För att jämföra krediter som beräknas enligt PEF och EN 15804, definieras en virtuell separat indikator för PEF för att beräkna alla krediter separat och jämföra resultaten med EN 15804 Modul D-resultat för att ge läsaren en översikt över de mest fördelaktiga användning av byggavfall enligt PEF och EN 15804. Olika sätt att minska subjektiviteten i valet av återvinningsgrad behandlas genom att utveckla mer transparenta och mindre subjektiva verktyg med hjälp av metoder från DGNB (German Sustainable Building Council) och BRE (Center for building research, UK). Energimarginal behandlas genom att integrera ett verktyg för energimarginaler från CDM (Clean Development Mechanism, FN) och hitta bidraget från olika material till miljöfördelarna i och efter livscykeln för byggnaden. DGNB och BRE metoderna kräver emellertid ytterligare utveckling, eftersom de inte ursprungligen är utvecklade för LCA-studier och bara används som de enda tillgängliga alternativen för att göra utvärderingsmetoder för återvinningsbarhet kompatibla med LCA-studier. Andra metoder, speciellt för LCA, kan också utvecklas i framtiden. Baserat på en inventering av komponenter och material som används i en riktig byggnad, genereras de största miljömässiga fördelarna (krediter) av nedströms återvinning av träprodukter när man använder EN 15804-formeln, medan aluminium ligger på andra plats. Å andra sidan är kommer aluminium i första hand och trä kommer på andra plats med PEFformeln. Aluminium har överlägset flest fördelar (krediter) per kg av varje material, på grundav den enorma återvinningspotentialen som aluminium har och kommer att ersätta primärt aluminium i framtiden. Till skillnad från PEF rapporterar EN 15804 alla krediter separat utanför LCA-systemgränsen. Detta är mycket fördelaktigt eftersom den korrekta verifierade LCAn inte kommer att påverkas av de krediter som ges baserat på nuvarande teknik när byggnadskomponenternas livslängd är mellan 40 och 120 år från idag.

Single use plastic products (SUPs) are a primary cause of plastic pollution causing significant environmental harm. These products have little to no value after use and are challenging to recycle cost efficiently. In a bid to combat this issue and foster circular economy, the European Union has declared a series of directives to gradually phase out SUPs as a strategy to eliminate these disposables from the market. This approach allows the market time to discover alternative solutions to replace SUPs, promoting the adoption of reusable products. To make a sustainable system of reusable products feasible and profitable, the key lies in devising a business model designed for a circular strategy of repeated use of goods. One effective approach involves establishing a closed-loop supply chain (CLSC) which entails the entire life cycle of a product, from sourcing raw materials, through manufacturing, utilisation, collection, reverse logistics and recycling. The purpose of this study was to develop a CLSC system for reusable plastic products between a plastic producing small or medium sized enterprise (SME) and an incumbent firm customer to attain a smooth transition from linear to circular economy. Employing an inductive approach, this case study considered the EU-directives as observational data, the change of business model as the result, and a general recommendation as the rule. The research method encompassed conducted interviews, mathematical prototyping, product design, and life cycle analysis, using various tools and methods in the process. Two case companies were involved: one large incumbent firm and one plastic producing SME. The aim was to design a circular business model (CBM) to capture the value of the collaboration between these two companies. After an analysation of the current situation, the main obstacles to a successful transition were identified. A comprehensive solution was developed, including a network of partners for the CLSC, a reusable product design, and the necessary implementation calculations. The finalised business model was anchored in the principles of the CLSC, the product design specifications and the calculations that determined the system’s viability. Implementation of the CBM would yield economic advantages for both stakeholders, as well as an improved green image factor and advancement in circular economy. Furthermore, this transition would cultivate valuable and lasting business relationships for both companies. These case findings harmonise with established theories which emphasise the significance of business models that are dependent on collaboration and long-term strategic planning. Lastly, they also underscore that value is created in product utilisation and not ownership.

This thesis investigates the integration of digital technologies (DT) within Product-Service Systems (PSS) and their role in promoting Circular Economy (CE) practices. Despite increasing recognition of digitalization in industries with PSS offerings, research on DT as a catalyst for CE, especially across organizations of various sizes, remains limited. This study explores how DT can revolutionize PSS, leading to more sustainable and efficient operations aligned with CE principles across varying industries sizes. The research employs a qualitative, multiple-case study approach, examining various industries to comprehend the diverse applications and implications of DT in PSS. Through an extensive review of existing literature and empirical data from case studies, the study identifies the implications, challenges, opportunities, and strategic dimensions of leveraging DT in PSS for CE. Key findings reveal that DT significantly enhances the efficiency, flexibility, and sustainability of PSS operations, aiding a transition towards CE. The study emphasizes the critical role of DT in resource optimization, waste reduction, and value creation, which are essential for sustainable business practices. However, it also underscores the diverse challenges faced by organizations, including technological adaptability, cost implications, and the need for tailored strategies across different organizational sizes. The thesis concludes with strategic insights for organizations, policymakers, and researchers, emphasizing the need for collaborative efforts to maximize the benefits of DT in PSS for promoting CE values. The study also advocates for a future where digital technologies are central to achieving a circular business model, and underlines the importance of strategic and effective technology adoption in the PSS sector. / Denna avhandling undersöker integrationen av digitala teknologier (DT) inom Produkt-Tjänstesystem (PSS) och deras roll i främjandet av praxis för cirkulär ekonomi (CE). Trots ökat erkännande av digitaliseringens roll inom industrier med PSS-erbjudanden, är forskningen om DT en katalysator för CE, särskilt för organisationer av olika storlekar, begränsad. Denna studie utforskar hur DT kan revolutionera PSS, vilket leder till en mer hållbar och effektiv verksamhet och metoder i linje med CE-principer över varierande industristorlekar. Forskningen använder en kvalitativ flerfallsstudieansats, och undersöker olika industrier för att förstå de mångsidiga applikationerna och implikationerna av DT i PSS. Genom en omfattande granskning av befintlig litteratur och empiriska data från fallstudier, identifierar studien implikationerna, utmaningarna, möjligheterna och de strategiska dimensionerna av att utnyttja DT i PSS för CE. Huvudsakliga slutsatser visar att DT avsevärt förbättrar effektiviteten, flexibiliteten och hållbarheten i PSS-verksamheter, vilket underlättar en övergång mot CE. Studien betonar DT:s kritiska roll i optimering av resurser, minskning av avfall och vidare värdeskapande, vilket är avgörande för att skapa en hållbar affär. Den lyfter dock också fram de mångfaldiga utmaningar som organisationer står inför, inklusive teknologisk anpassningsförmåga, kostnadsimplikationer och behovet av skräddarsydda strategier för olika organisatoriska storlekar. Avhandlingen avslutas med strategiska insikter för organisationer, beslutsfattare och forskare, och betonar behovet av samarbetsinsatser för att maximera fördelarna med DT i PSS för att främja CE-värderingar. Den förespråkar en framtid där digitala teknologier är centrala för att uppnå cirkulära affärsmodeller, och understryker vikten av strategisk och effektiv teknologiimplementering i PSS-sektorn.

[pt] Através de sua abordagem restaurativa e regenerativa por princípio, a economia circular é capaz de trazer inúmeros benefícios quando combinada às práticas de agricultura orgânica, que consistem na produção de alimentos livres de contaminantes e que preza pela segurança e valorização do homem e do meio ambiente. Nesse estudo, a relação entre os dois temas será analisada sob o contexto da cafeicultura orgânica, setor que tem apresentado fortes tendências de crescimento e um amplo campo de desenvolvimento para novas práticas ao longo de toda a sua cadeia de suprimentos. O café é carbono negativo e capaz de ter seu ciclo completamente fechado, podendo ser reinserido de forma integral e segura no meio ambiente. A análise foi realizada utilizando os preceitos da metodologia ReSOLVE, desenvolvido pela Ellen MacArthur Foundation (regenerar, compartilhar, otimizar, ciclar, virtualizar e trocar) em empresas que produzem e/ou comercializam café orgânico, verificando a sua devida aplicabilidade ao longo das respectivas cadeias de suprimentos. O presente estudo é uma pesquisa qualitativa de caráter descritivo. Para isso, foram desenvolvidos estudos de casos com a realização de entrevistas estruturadas em profundidade com os atuais proprietários das empresas focais e a triangulação de dados, buscando validar sua confiabilidade. O resultado dessa pesquisa evidencia como a aplicação da economia circular nos modos de produção da cafeicultura orgânica é capaz de potencializar os resultados obtidos, através da cooperação e integração de sua cadeia de suprimentos, mas também constata a presença de algumas barreiras importantes a sua plena implementação. / [en] Through its restorative and regenerative approach by principle, the circular economy is able to bring numerous benefits when combined with organic farming practices, which consists in producing food free of contaminants and that values the safety and enhancement of man and the environment. In this study, the relationship between the two topics will be analyzed in the context of organic coffee farming, a sector that has shown strong growth trends and a wide field for the development of new practices throughout its supply chain. Coffee is carbon negative and capable of having its cycle completely closed, and can be fully and safely reinserted into the environment. The analysis was carried out using the precepts of the ReSOLVE methodology, developed by the Ellen MacArthur Foundation (regenerate, share, optimize, cycle, virtualize and exchange) in companies that produce and/or sell organic coffee, verifying its proper applicability along the respective supply chains. The present study is a qualitative research of descriptive character. To this end, case studies were developed with structured in-depth interviews with the current owners of the focal companies and data triangulation, seeking to validate its reliability. The result of this research shows how the application of the circular economy in organic coffee production methods is able to enhance the results obtained, through cooperation and integration of its supply chain, but also notes the presence of some important barriers to its full implementation.

Financial performance measurement plays an important role in leading decision-makers through strategic innovation, such as business model innovation. To convey relevant information, it is important that the practices used to measure financial performance are appropriate to what is being measured. This thesis focuses on the financial performance measurement supporting the transition towards circular business models (CBMs), which has been under-researched. More specifically, this thesis aims to identify the key practices that enable the financial performance measurement of CBMs and support the transition from linear business models to CBMs. Additionally, it seeks to contribute with insights about the financial outcomes of CBMs in the context of sustainable-oriented technologies. This thesis consists of a compilation of three papers, a systematic literature review and two empirical studies. The outset of this thesis lies in the systematic literature review, which examines the financial aspects addressed in CBM literature and in relation to the transition towards CBMs. The empirical studies examine the financial performance measurement practices that support the transition towards two different types of CBMs, namely result- oriented CBMs and sufficiency-driven CBMs. Both studies are based on an action case study, which involved collaborative development of financial performance measurement tools with practitioners from the manufacturing industry. The results of this thesis emphasize the customer-centric aspect of financial performance measurement of CBM. The key practices identified by this thesis suggest considering costs involved in customer-value creation when measuring performance. The findings also highlight the importance of taking the offering perspective for defining the cost structure and engaging with customers early in the transition to reduce uncertainty about future cash flows and hidden costs. Life Cycle Costing (LCC) is proposed as a measurement technique. However, the results suggest adapting the LCC perspective, by addressing providers’ or users’ cost, to satisfy the different needs of decision makers. To cover the long-term returns of the CBM offering, multiple use cycles of the offering and of its underlying assets should be considered in the LCC. In terms of cost management, the findings of this thesis suggest an outside-in approach to reduce costs while enhancing customer value creation and re-creation. Finally, this thesis underscore the necessity of employing the recommended practices from various evaluation perspectives to bolster the iterative transition process toward CBMs. Regarding the financial outcomes of CBMs, this thesis shows that the transition towards CBMs in the context of sustainability-oriented technologies holds promising financial advantages for both providers and customers. Technological innovation and retained product ownership contribute to improving the financial performance of CBMs. / Finansiell prestationsmätning spelar en viktig roll när det kommer till att vägleda beslutsfattare genom strategiska innovationer. Avhandlingen syftar till att identifiera de viktigaste praktiker som möjliggör finansiell prestationsmätning av cirkulära affärsmodeller och som stödjer övergången från linjära affärsmodeller till cirkulära affärsmodeller. Dessutom strävar avhandlingen efter att bidra med insikter om lönsamhet för företag som introducerar cirkulära affärsmodeller i samband med införandet av hållbara teknologier. Denna avhandling består av tre artiklar och en kappa. Artiklarna utgörs av en systematisk litteraturöversikt samt två empiriska studier. Avhandlingens utgångspunkt är den systematisk litteraturöversikten, som granskar de ekonomiska aspekter som behandlas i litteraturen om cirkulära affärsmodeller samt i relation till övergången från linjära till cirkulära affärsmodeller. De empiriska artiklarna undersöker de praktiker för finansiell prestationsmätning som stödjer övergången till två olika typer av cirkulära affärsmodeller. Dessa är resultatorienterade cirkulära affärsmodeller och suffiency-driven cirkulära affärsmodeller. Båda studierna bygger på aktionsbaserade fallstudier som involverar samarbete med stora tillverkningsföretag. Avhandlingens resultat framhäver ett kundcentrerat perspektiv vid finansiell prestationsmätning av cirkulära affärsmodeller. En av de viktigaste praktikerna för prestationsmätning som identifierats betonar vikten av att hänsyn tas till kostnader som är involverade i att skapa kundvärde. Resultaten understryker också vikten av att överväga hela erbjudandet som perspektiv när kostnadsstrukturen definieras. Beräkning av livscykelkostnaden (LCC) föreslås som mätmetod. Resultaten visar dock på vikten av att LCC anpassas genom att ta hänsyn både till leverantörers och användares kostnadsstrukturer för att tillgodose beslutsfattares olika behov. För att möjliggöra en långsiktig lönsamhet i en cirkulär affärsmodell bör flera användningscykler för den ingående tillgången ingå i erbjudandet till kund redan vid affärsmodellens designstadium. Cirkulära erbjudanden kan medföra både ökade och reducerade kostnader samt kassaflödesförändringar på systemnivå. Dessa förändringar föreslås att inkluderas i mätningen av cirkulära affärsmodellers finansiella prestation. Vidare framhåller resultaten behovet av att använda föreslagna praktiker utifrån olika utvärderingsperspektiv för att stödja en övergångsprocess mot cirkulära affärsmodeller. Slutligen, när det gäller lönsamheten för cirkulära affärsmodeller indikerar avhandlingens resultat att övergången från linjära till cirkulära affärsmodeller medför potentiella ekonomiska fördelar för både leverantörer och kunder. Teknologisk innovation samt behållande av produktägande i en cirkulär affärsmodell kan bidra till att förbättra en industriell tillverkares ekonomiska prestation. / <p>Funding agencies: MISTRA REES, VINNOVA, Division of Business Administration at Linköping University</p>

Detta examensarbete är tillägnad att undersöka hur affärsmodellsinnovation kan skapa förutsättningar för att underlätta återanvändandet av elbilsbatterier samt analysering av möjliga värdeskapande utfall. Arbetet fokuserar på att samla data från större aktörer som hanterar begagnade elbilsbatterier. Kartläggning av deras affärsmodeller genom kvalitativa intervjuer ger läsaren och författarna en större inblick kring hur cirkulära affärsmodeller fungerar och vart de behöver innovation.  Elbilar har det senaste decenniet en större andel av nybilsförsäljningen och med direktiv från både EU och den svenska staten, kommer det ebdast vara möjligt att köpa eldrivna samt vissa gasdrivna fordon från 2035. Detta medför en större batteriproduktion vilket även leder till en större grad av exploatering av nuvarande litium- och molybden reserver. Dessa reserver kommer att räcka i ca 70 år om inte nya tillgångar upptäcks och större fokus på att kunna återanvända blir aktuellt.  Denna omfattande gröna omställning av bilindustrin sätter även press på batteri producenter till en mer hållbar tillverkning som tar hänsyn till behovet av att kunna återvinna/återanvända. Denna eftertraktade designförslag är däremot något nytt hos många producenter och resterande verkar inte kunna nå en optimal grad av återvinningsberhet. Kvar blir alternativet att kunna återanvända batterierna från den befintliga elbilsmarknaden. Denna studie inspireras av cirkulär ekonomi och cirkulära affärsmodeller som kan effektivt handskas med problemen dem begagnade elbilsbatterierna för med sig. Studiens forskningsfrågor grundar sig först och främst hur befintliga affärsmodeller ser ut, vad för innovation det krävs samt hur denna innovation kan skapa förutsättningar för återanvändning.  Kartlägning av affärsmodeller från större återanvändning/återvinnings aktörer såsom Northvolts dotterföretag Revolt samt Stena Recycling, BatteryLoop, visar på ett behov av en mer intergrerad spårning och distrubering av själva elbilsbatterierna. Studien visar att affärsmodellsinnovation behövs inom uppsamling av begagande elbilsbatterier där en digital plattform möjliggör interaktion mellan köpare och säljare. Dessutom kontrolleras varje begagnat batteri innan den når marknaden vilket skapar fler förutsättningar för cirkularitet och främjar återvinning. / This thesis is dedicated to investigating how business model innovation can create the conditions to facilitate the reuse of electric car batteries as well as analyzing possible value-creating outcomes. The work focuses on gathering data from major players who handle used electric car batteries. Mapping their business models through qualitative interviews gives the reader and the authors a greater insight into how circular business models work.  In the last decade, electric cars have taken larger share of the new car sale och with directives from both the EU and the Swedish state, it will only be possible to buy electric-powered abd sin gas-powered vehicles from 2035. This entails a greater battery production, which also leads to a greater degree of exploitation of current lithium and molybdenum reserves. These reserves will last for about 70 years unless new assets are discovered and a greater focus on being able to reuse and recycle becomes relevant.  This comprehensive green transformation of the car industry also puts pressure on battery producers to a more sustainable production that considers the need to be able to be recycled/reused.However, this sought-after design proposal is something new for many producers and the rest do not seem to be able to reach an optimal degree of recyclability. What remains is the option of being able to reuse the batteriers from the existing electric car market. This study is inspired by circular economy and circular business models that can effectively deal with the problems that used electric car batteries bring with them. The study's resarch questions are first and foremost based on what existing business models look like, what kind of innovation is required and how this innovation can create conditions for reuse. Mapping of business models from major reuse/recycling actors such as North Volts's subsidiary Revolt and Stena Recycling, Battery Loop, shows a need for more intergrated tracking and distribution of the electric car batteriers themselves.  This study shows that business model innovation is needed in the collection of used electric car batteries where a digital plattform enables interaction between buyers and sellers. In addition, every used battery is checked before it reaches the market, which creates more conditions for circularity and promotes recycling.
