In this essay, the Scanlonian contractualist formula will be understood as follows: Within the domain of morality of what we owe to each other, an action is morally wrong if it follows principles that similarly motivated people can reasonably reject. Consequently, the concept of ‘reasonable rejection’ is the operative element in moral valuation, thus begging the question of what it is for a rejection to be reasonable. The problem of circularity in Scanlon’s contractualism builds upon a reading according to which Scanlon’s explanation of what it is to be ‘reasonably rejected’ seems to be understood as ‘when the action is morally wrong’. If this is the case, then Scanlon’s contractualism refers to its own thesis when performing moral valuations: that is wrong which can be reasonably rejected, and for an action to be reasonably rejected it must be morally wrong. The problem of circularity apparently renders Scanlon’s contractualism ‘empty’ as it cannot explain what it is for an action to be morally wrong without referring to its own thesis. In this essay I will try to clarify the difference between welfarist and structural charges of circularity. I will argue that the structural charges of circularity are due to a fallacious constructivist reading of What We Owe to Each Other. As I understand Scanlon, the constructivist reading places Scanlon’s theory too close to the contractualist tradition. I will also argue that critics holding Scanlon’s contractualism to be circular have failed to note that his theory only claims to cover a narrow domain of morality. Where critics hold Scanlon’s contractualism to refer to its own thesis when performing moral valuations I will argue that the theory refers to moral domains outside that of what we owe to each other. Hopefully my discussion on constructivism and circularity will shed some light on the simple brilliance and practical applicability of Scanlon’s contractualism. I will give a brief overview of What We Owe to Each Other before I present the critique put forth by Onora O’Neill, Mark Timmons and Joseph Raz. Then I will show how Scanlon treats the problem of circularity in his book, and how his defense targets substantial and not structural charges of circularity. I will then show that the structural critique is fallacious by analyzing the domain of morality that Scanlon’s contractualism targets. Finally I will try to apply Scanlon’s formula on personal relationships and on environmental issues. As of this point I will refer to Scanlon’s thesis as ‘contractualism’ while other theories following the contractualist tradition will be referred to as ‘contractarian’.

This dissertation motivates and defends what I call non-inferential epistemic circularity. Traditionally epistemic circularity is understood to be a property of arguments, where justification to believe these arguments’ premises depends upon the truth of their conclusions. I argue that epistemically circular arguments face a dilemma. If the conditions for non-inferential justification to believe their premises are too weak, these arguments are either indiscriminate or permit one to bootstrap trivially to higher-order justification. If to avoid these problems the conditions for non-inferential justification are strengthened on the basis of evidence, then epistemically circular arguments beg the question because they collapse into logical circularity. To address these problems I argue that an account of non-inferential justification should be developed that limits the role of evidential grounds and finds room instead for non-evidential sources of justification. I conclude that epistemic circularity is constitutive of non-inferential justification because it is a property of the intentional acts in virtue of which this justification is earned.

This thesis presents how circularity indicators successfully can be used to generate concrete design improvements for commercial machines with the aim of making them better adapted to the Circular Economy. By using a methodology based on workshops, assessment of circular maturity from BS8001:2017- Framework for implementing the principles of the circular economy in organizations – guide, and use of the circularity indicator Circularity Measurement Toolkit (CMT) a fully automated coffee machine became 4 percent improved in the circular performance and an 80 percent landfill waste reduction was achieved. As Circular Economy is becoming more accepted as the idea of moving forward towards a more sustainable future, topics on how to measure circularity for organizations and products are increasing. Apart from using circularity indicators together with ecodesign strategies in a case for the first time, this thesis also investigates how a  circular transition of a manufacturing company can be communicated to stakeholders.  With a slight modification of the circularity indicator CMT, the assessment provided a percentage on how circular a fully automated coffee machine is. Identified hotspots in the CMT, matched with areas with improvement potential at the case company, results in three concepts of improvement suggestions. The three concepts are: (1) a modular front to the machine to enable remanufacturing/recycling of the front, presents the option of changing the look of the machine without buying a new one, and lowers the amount of landfill waste, (2) The identity of Luna the barista is integrated into the interface of the coffee machine for emotional durability, and (3) suggestions of how a company can communicate their circular transition through sustainability reports are presented. Both the methodology, the use of circularity indicators to generate design suggestions, and the general idea of concepts are believed to be applicable to any commercial machine in order to improve the circular performance.

Addressing environmental burdens associated with the operation and infrastructure of the electrical transmission system products is imperative. Implementing Ecodesign practices in the early stages of product development and adopting circularity approaches throughout the product value chain is crucial to mitigate adverse impacts. However, transitioning from a traditional to a circular business model necessitates a well-defined strategic plan enabling organisations to assess their current situation and develop effective tactics. Nevertheless, trade-offs between circularity and sustainability must be carefully considered, as circular practices may not always align with the triple bottom line. Therefore, accurately prioritising circular strategies is essential for establishing a circular and sustainable product life cycle. This research evaluates business practices of Grid Solutions and proposes priority strategies, guidelines and KPIs to enhance product circularity. For this purpose, the Analytic Hierarchy Process (AHP), a Multi-Criteria Decision-Making (MCDM) methodology based on expert’s judgment, is implemented. The prioritised strategies are analysed using an Importance vs Difficulty matrix to identify high-value and strategic actions. Simultaneously, product circularity indicators are evaluated and ranked based on the AHP outcomes. Subsequently, the most relevant indicator is assessed through Life Cycle Assessment (LCA) in the prioritised guidelines, through High Voltage (HV) equipment. Results highlight that minimising energy consumption is essential for improving product circularity, as LCA analysis confirms. The chosen circular indicator is tested by comparing an HV product version with lower energy losses to the product baseline, exhibiting a 51.45% increase in sustainable circularity and approximately 20% reduction in adverse environmental impacts. Additionally, prioritising efforts to minimise non-conformities, promote repairability, and enable upgrades are also of high relevance. Finally, the research provides recommendations for New Product Introduction (NPI) frameworks and sustainable reporting.

The rate at which the human race is exhausting the planet’s resources, a transition from a linear economy to a circular economy has become necessary. More importantly the success of circular economy is dependent on the consumer’s everyday actions and practices. This project looks to contribute to that smooth transition at a consumer behavior level of furniture consumption through market actions. It specifically focuses on the sustainable consumption of the sofas to be able to collect data and actionable insights so that it can serve as an example that can be applied to all types of furniture. The project created a framework from literature review on consumer behavior of furniture, sustainability and circular economy. Furthermore, it used several design methods to collect and analyze the data, before arriving at the final design project. The resulting project is called the ‘culture of care’. Based on the collected actionable insights throughout the project, the culture of care project proposes several circular based market actions in the form of service design, product design and product-service design to maintain and repair sofas in the hands of the consumers.

This thesis concerns infinite words over finite alphabets. It contributes to two topics in this area: critical exponents and stabilizers. Let w be a right-infinite word defined over a finite alphabet. The critical exponent of w is the supremum of the set of exponents r such that w contains an r-power as a subword. Most of the thesis (Chapters 3 through 7) is devoted to critical exponents. Chapter 3 is a survey of previous research on critical exponents and repetitions in morphic words. In Chapter 4 we prove that every real number greater than 1 is the critical exponent of some right-infinite word over some finite alphabet. Our proof is constructive. In Chapter 5 we characterize critical exponents of pure morphic words generated by uniform binary morphisms. We also give an explicit formula to compute these critical exponents, based on a well-defined prefix of the infinite word. In Chapter 6 we generalize our results to pure morphic words generated by non-erasing morphisms over any finite alphabet. We prove that critical exponents of such words are algebraic, of a degree bounded by the alphabet size. Under certain conditions, our proof implies an algorithm for computing the critical exponent. We demonstrate our method by computing the critical exponent of some families of infinite words. In particular, in Chapter 7 we compute the critical exponent of the Arshon word of order n for n ≥ 3. The stabilizer of an infinite word w defined over a finite alphabet Σ is the set of morphisms f: Σ*→Σ* that fix w. In Chapter 8 we study various problems related to stabilizers and their generators. We show that over a binary alphabet, there exist stabilizers with at least n generators for all n. Over a ternary alphabet, the monoid of morphisms generating a given infinite word by iteration can be infinitely generated, even when the word is generated by iterating an invertible primitive morphism. Stabilizers of strict epistandard words are cyclic when non-trivial, while stabilizers of ultimately strict epistandard words are always non-trivial. For this latter family of words, we give a characterization of stabilizer elements. We conclude with a list of open problems, including a new problem that has not been addressed yet: the D0L repetition threshold.

Background: Due to the escalated environmental concerns and the requirement of Paris Agreement, restraining the carbon emission is aimed on a global scale. Being a solution, the electrification of vehicles is inevitable whilst the problematization to the batteries continues. Many strategies, from improving the battery default as a product, to servitizing the batteries in the light of servitization, has been attempted by both battery suppliers and car manufacturers. In connection to sustainability concerns, which refers to the battery End-of-Life (EoL) Management, however, not many scholars believe that circular economy for electric vehicle batteries can shape itself. Deeming the massive adoption of electric vehicle as the foundation of circular economy, some scholars advocate, that servitization can propel the execution of sustainable goal when it changes the ownership of batteries from customers to manufacturers.  Purpose: The proposed relationship of battery servitization and sustainability is standing alone shortly since 2020 without much evidence support. Hence, it is put on the list of examination to identify the motives and interest of manufacturers by offering battery servitization. Moreover, owing to the fact that the literature of battery servitization is seen segmented for only single dimensioned service type, it is also aimed by this thesis to coin the status-of-art of battery servitization from the empirical study, with customers’ perspective included.  Methodology: This thesis is designed based on a mixed method including qualitative interviews and quantitative surveys to answer the research questions that none of the methods could answer alone. Both inductive and deductive approaches were adopted due to the discrepant results from the empirics. Particularly, triangulation design, obtaining different yet complementary data to study the same topic, is followed to structure the discussion.  Findings & Conclusion: Generally, the findings answer the purpose of writing this thesis well. From qualitative study, battery servitization is more of a marketing strategy and not after a goal of building the circularity. However, sustainability is deployed by manufacturers of all levels in the supply chain. Additionally, Battery-as-a-Service (BaaS) as an all-round service solution is enlarging the content to servitize. Further, not being much aware of though, battery servitization is enabling the circularity of batteries owing to the respective battery strategies of each manufacturer. This is to say, sustainability is considered in combination of battery servitization, as the theoretical base of this thesis suggests. From quantitative study, customers’ satisfaction level proves that the manufacturers’ aimed goal is partly achieved. However, to use battery servitization as a marketing strategy for electric vehicle adoption, which indirectly facilitate sustainability, it should be invested more efforts to help more potential customers accept it.

Battery electric vehicles (BEV) powered by renewable energy are expected to enable a largedecarbonization of the land-based transport. Recent estimations of the International EnergyAgency suggest that BEVs could grow 20-fold by 2030, reaching 200 to 350 million unitsglobally. However, the environmental impacts of BEVs remains a critical issue to be addressed.Batteries are responsible for 80% of the life cycle environmental impacts of BEVs, mainly dueto the extraction of raw materials, manufacture and charge. A concept that aims at avoiding theexploitation of new materials by extending the lifetime of resources and products is circularity.Among various circular business models, one that so far has not been substantially addressedin the literature is battery leasing.This thesis investigates the economic and environmental impacts of leasing batteries for BEVsas a circular business model and compares them to those of the linear model of selling-buyingbatteries. For doing this, we combine three models, namely a battery fleet model, a net presentvalue (NPV) model and a cradle-to-grave life cycle assessment (LCA). In contrast to commonLCAs, our battery fleet model considers different types of driving profiles instead of the typical‘average’ profile, which offers a more accurate depiction of reality.Results indicate that leasing batteries may be as profitable as selling them, but leasingcompanies may require higher revenues and pay higher taxes to attain the same NPV as selling.To generate more income, companies would need to charge fees to customers that are notalways beneficial for them. In fact, buying the battery remains the cheapest option for usersdriving more than 10 thousand km/year, which is the majority. From an environmentalperspective, LCA results show that environmental benefits of leasing batteries compared toselling them are marginal. This suggests that while leasing batteries offer some advantages(e.g., making BEVs more affordable, facilitating flexibility to users, promote the repairing,repurpose and recycling of batteries, etc.), it is unlikely to improve the cost-effectiveness andenvironmental impact of buying/selling them.
