Uppsatsen syftar till att bidra med kunskap kring de svårigheter och de barriärer som föreligger vid en implementering av en cirkulär affärsmodell. Studien utgår från ett företagsperspektiv, vilket även kompletterats med ett kundperspektiv för att skapa ett holistiskt perspektiv. Uppsatsen inkluderar undersökningar kring de anställdas uppfattningar, i avseende att identifiera eventuella barriärer. Vidare inkluderas även undersökningar kring kundernas uppfattningar av IKEA:s cirkulära arbete. En kvalitativ ansats har använts då en fallstudie på ett IKEA-varuhus i Mellansverige genomförts. Ostandardiserade och halvstrukturerade intervjuer har skett, där sex anställda deltog i djupare intervjuer och nitton besökare på IKEA-varuhuset deltog i mer kortvariga intervjuer. Data användes sedan för en analys och diskussion i förhållande till tidigare forskning. Den mest omfattande barriären som upptäckts på fallstudiens enhet är kommunikation, där både den interna kommunikationen visar på brister kring bland annat informationsdelning, samt den externa kommunikationen gentemot kunder i sin helhet. Vidare belyser uppsatsen brister kring varuhusets företagskultur där hållbarhetsutbildningen är återhållsam, samt har distinkta skillnader framgått i de anställdas motivation. För en lyckad omställning av cirkulär affärsmodell behövs extern och intern kommunikation, långsiktig intern utbildning, samt motivation för att driva cirkulära innovationer. / The main aim of this thesis is to assess, understand and contribute to the challenges and barriers related to the implementation of a circular business model. The thesis applied a holistic perspective where both organizational and customer perspectives are studied. In this study, we assess both employees and customers perceptions regarding the transition to a circular way of doing things in order to identify eventual barriers and challenges. The study has a qualitative approach with a case study of an IKEA store in the central part of Sweden. We have used semi-structured and unstandardizedinterviews, where six employees of IKEA participated in more insightful interviews and nineteen customers participated in short interviews. The collected data was used for analysis and discussion in relation to previous research (theoretical framework). In this study, we have found that the vital barrier in the IKEA store is communication, for instance, the circular informational sharing is lacking in internal communication. The external communication towards customers is also inadequate. Furthermore, some difficulties regarding the corporate culture of IKEA is emphasized. The education concerning sustainability and circular economy is restrained and distinctions in employee motivation has emerged. In order to success, business need a readjustment towards a circular business model implementation, long-term education is necessary to create knowledge, while motivating the employees in order to facilitate circular innovations.

Printed and organic electronics have been intensely researched in the past few years, and their potential low-cost and sustainability benefits combined with their unique form properties makes them interesting from a product design perspective. However, there has been a lack of product design with printed and organic electronics, which has created a gap between research and market. The aim of this thesis is to find an application of printed and organic electronics in a previously unexplored application area. The thesis includes interviews and workshops with relevant actors, a SWOT analysis, and idea generation through brainstorming. It is found that printed and organic traceability tags (RFID/NFC) have the potential to facilitate circular business models in the fashion industry if they are developed to fulfil the identified requirements.  Three concepts of how traceability tags can facilitate rental fashion are developed. The main identified potential benefits for the rental companies are reduced logistics costs and the possibility of data collection. The potentially low cost of printed and organic traceability tags would also enable rental companies with smaller profit margins to implement a digital traceability solution which would help the survival of these companies and accelerate the shift towards circular fashion. These findings contribute with a new possible application of printed and organic electronics. In order to reach the identified benefits, more research on printed and organic traceability tags is needed, as well as a full product development process of the three concepts. To really know whether this and other identified applications of POE could be viable on the market there is a need for economic and performance analysis to determine whether their applications can be successful. Further the authors also see a need for life cycle analyses on all types of POE applications to determine their environmental impact.

Tesis por compendio / [ES] Los viroides son los patógenos con replicación autónoma más simples y sólo se han encontrado de forma natural infectando plantas superiores. Desde que se descubrieron en los años setenta, se ha adquirido un conocimiento considerable sobre su naturaleza y mecanismos de replicación en las plantas huésped. Sin embargo, aún quedan por descubrir muchos aspectos de la biología de los viroides. Por lo tanto, un conocimiento más profundo de la naturaleza y el modo de acción de los viroides han sido los objetivos principales que engloban esta tesis. Para ello, es esencial contar con procedimientos sencillos y eficientes para la obtención de clones de ADNc infecciosos. Se desarrolló un nuevo método eficiente para construir clones de viroides infecciosos y se probó con un viroide de cada familia: El viroide latente de la berenjena (ELVd, Avsunviroidae) y el viroide del lúpulo (HSVd, Pospiviroidae). Esta aproximación se basó en enzimas de restricción de tipo IIS que cortan fuera del sitio de reconocimiento y supone un procedimiento universal para obtener clones infecciosos de un viroide independientemente de su secuencia, con una alta eficiencia. A pesar de que los viroides han sido considerados como ARN no codificantes desde su descubrimiento, nuestro análisis computacional predijo pequeños marcos de lectura abiertos en cada uno de los genomas de HSVd y ELVd. No se encontraron similitudes significativas con las proteínas de la base de datos de plantas superiores, pero algunos de estos péptidos predichos estaban altamente conservados entre todas las variantes de HSVd y ELVd. Curiosamente, la fusión de estas secuencias conservadas con una proteína fluorescente reveló una localización subcelular específica en el correspondiente orgánulo donde tiene lugar la replicación/acumulación para cada viroide: nucleolo y cloroplasto para HSVd y ELVd, respectivamente. Las mutaciones que truncan el dominio nucleolar de HSVd fueron perjudiciales para el viroide, mientras que el truncamiento de cualquiera de los dos ORF de ELVd que contiene una señal de localización al cloroplasto también disminuyó (pero en menor medida) la eficiencia biológica del viroide, tal vez debido a la redundancia funcional. Se encontraron formas circulares de los ARN de HSVd y ELVd en fracciones polisómicas, lo que revela su interacción física con la maquinaria de traducción de la célula vegetal. En conjunto, estas observaciones experimentales indican que no se puede descartar la capacidad de codificación de los viroides, aunque la prueba definitiva (la detección de los péptidos codificados por los circRNAs) es un reto tecnológico que deberá abordarse en futuras líneas de investigación. Finalmente, para estudiar qué cambios se producen en el huésped durante la infección con un viroide sintomático, se realizó un análisis integrador de las alteraciones genómicas de plantas de pepino infectadas con HSVd. Se integraron los transcriptomas, el sRNAnomas y el metilomas para determinar la respuesta temporal a la infección por el viroide. Nuestros resultados apoyan que el HSVd promueve el rediseño de las vías reguladoras del pepino afectando predominantemente a capas reguladoras específicas en diferentes fases de la infección. La respuesta inicial se caracterizó por una reconfiguración del transcriptoma del hospedador mediante el uso diferencial de exones, seguido de una predominante regulación a la baja de la actividad transcripcional modulada por los cambios epigenéticos del hospedador asociados a la infección y caracterizada por un aumento de la hipermetilación. Las alteraciones en el metabolismo de los ARN pequeños y microARNs del huésped fueron marginales y se produjeron principalmente en la fase tardía. En general, estos datos constituyen el primer mapa exhaustivo de las respuestas de la planta a la infección de un viroide. / [CA] Els viroids són els patògenes més simples amb replicació autònoma i només s'han identificat de forma natural infectant a plantes superiors. Des que es descobriren als anys setanta, s'ha adquirit un coneixement considerable sobre la seua natura i els mecanismes de replicació en plantes hoste. No obstant, encara queden per descobrir molts aspectes de la biologia dels viroids. Per tant, un coneixement més profund de la natura i el mode d'acció dels viroids han sigut els objectius principals que engloben aquesta tesi. Per a això, és essencial la disponibilitat de procediments senzills i eficients per a l'obtenció de clones infecciosos. Es va desenvolupar un nou mètode eficient per a construir clones infecciosos y es fa provar amb un viroid de cada família: el viroide latent de la albergínia (ELVd, Avsunviroidae) y el viroid del llúpol (HSVd, Pospiviroidae). Aquesta aproximació es basà en enzims de restricció de tipus IIS que tallen fora del lloc de reconeixement i suposa un procediment universal per obtenir clones infecciosos de un viroid independentment de la seua seqüencia amb una elevada eficiència. Tot i que els viroids s'han considerat com ARNs no codificants des del seu descobriment, el nostre anàlisi computacional va predir xicotets ORF als genomes de HSVd y ELVd. No es trobaren similituds significatives amb proteïnes depositades a les bases de dades, però alguns d'aquest pèptids estaven altament conservats a les variants de HSVd y ELVd. Curiosament, la fusió d'aquestes seqüencies conservades amb una proteïna fluorescent revelà una localització subcel·lular especifica al orgànul on te lloc la replicació/acumulació de cada viroid: nuclèol i cloroplast per a HSVd i ELVd, respectivament. Les mutacions que trunquen el domini nucleolar de HSVd foren perjudicials per al viroid, mentre que el truncament de qualsevol de les dos ORF de ELVd que contenen una senyal de localització al cloroplast també va disminuir (però en menor mesura) l'eficiència biològica del viroid, el que pot ser degut a una redundància funcional. Es detectaren formes d'ARN circular de HSVd i ELVd a les fraccions polisòmiques, el que revela la seua interacció física amb la maquinaria de traducció cel·lular. En conjunt, aquestes observacions experimentals indiquen que no es pot descartar la capacitat codificants dels viroids, encara que la evidencia definitiva (la detecció del pèptids codificats per ARN circulars) es un repte tecnològic que s'haurà d'adreçar en línies d'investigació futures. Finalment, per tal d'estudiar que canvis es produeixen a l'hoste durant la infecció amb un viroid simptomàtic, es va realitzar un anàlisi integrador de les alteracions genòmiques de les plantes de cogombre infectades amb HSVd. S'integraren els transcriptomes, sARNomes i metilomes per determinar la resposta temporal a la infecció per viroid. Els resultats obtinguts suporten que HSVd promou un redisseny de les vies reguladores de cogombre afectant predominantment a nivells reguladors específics a les diferents etapes de la infecció. La resposta inicial es caracteritzà per una reconfiguració del transcriptoma de l'hoste mitjançant l'ús diferencial d'exons, seguit d'una repressió transcripticional modulada per canvis epigenètics de l'hoste caracteritzats per una major hipermetilació. Les alteracions al metabolisme de ARN xicotets i microARNs de l'hoste van ser marginals i es produïren principalment al final de la infecció. En general, aquestes dades constitueixen el primer mapa exhaustiu de les respostes de la planta a la infecció per un viroid. / [EN] Viroids are the simplest pathogens with autonomous replication and have only been found naturally infecting higher plants. Since viroids were discovered in the seventies, we have gained considerable knowledge about their nature and replication mechanisms in host plants. However, many aspects of viroid biology are yet to be discovered. Therefore, a deeper understanding of the nature and mode of action of viroids have been the encompassing main goals of this thesis. For this purpose, simple and efficient procedures for obtaining infectious cDNA clones are essential. A new efficient method for constructing infectious viroid clones was developed and tested with one viroid of each family: eggplant latent viroid (ELVd, Avsunviroidae) and hop stunt viroid (HSVd, Pospiviroidae). This procedure was based on type IIS restrictions enzymes that cut outside of the recognition site and supposes a universal procedure for obtaining infectious clones of a viroid independently of its sequence, with a high efficiency. Despite viroids have been considered as plant-pathogenic non-coding RNAs since their discovery, our computational analysis predicted small open reading frames in each of the HSVd and ELVd genomes. No significant similarities with proteins in the database of higher plants were found, but some of these predicted peptides were highly conserved among all HSVd and ELVd variants. Interestingly, the fusion of these conserved sequences to a fluorescent protein revealed a specific subcellular localization in the corresponding organelle where replication/accumulation takes place for each viroid: nucleolus and chloroplast for HSVd and ELVd, respectively. Mutations that truncate the nucleolar domain of HSVd were detrimental for the viroid while truncating any of the two ELVd ORF that contains a chloroplast transit signal also diminished (but to a lesser extent) viroid biological efficiency, maybe because of functional redundancy. Circular forms of both, HSVd and ELVd RNAs were found in polysome fractions, revealing their physical interaction with the translational machinery of the plant cell. Altogether, these experimental observations indicate that the coding capacity of viroids cannot be ruled out, although the definitive evidence (detection of the circRNA-encoded peptides) is a technological challenge to be addressed in future research lines. Finally, to study the host changes that are produced during a symptomatic viroid infection, an integrative analysis of the timing and intensity of the genome-wide alterations in cucumber plants infected with HSVd was performed. Differential host transcriptome, sRNAnome and methylome were integrated to determine the temporal response to viroid-infection. Our results support that HSVd promotes the redesign of the cucumber regulatory-pathways predominantly affecting specific regulatory layers at different infection-phases. The initial response was characterized by a reconfiguration of the host-transcriptome by differential exon usage, followed by a predominant down-regulation of the transcriptional activity modulated by the host epigenetic changes associated to infection and characterized by increased hypermethylation. The alterations in host sRNA and microRNA metabolism were marginal and mainly occurred at the late stage. Overall, these data constitute the first comprehensive map of the plant responses to a viroid infection. / La Conselleria d’Educació, Investigació, Cultura i Esports (Generalitat Valenciana) y el Fondo Social Europeo (FSECV 2014-2020) han cofinanciado la contratación del doctorando como personal investigador de carácter predoctoral (ACIF/2017/114) y unas estancias predoctorales fuera de la Comunitat Valenciana (BEFPI/2020).

[pt] O Brasil é o segundo maior produtor de lixo eletrônico das Américas, com uma produção que cresce a cada ano e apenas 10 por cento dela sendo tratada de forma apropriada. Adicionalmente, o Brasil não possui tecnologia própria para tratamento de placas de circuito impresso, componente chave presente neste tipo de resíduo. Atualmente, o Brasil não possui uma planta industrial voltada para essa atividade extrativista a partir de resíduos eletrônicos, sendo a maior parte do seu tratamento realizado no exterior. A hipótese de pesquisa deste manuscrito é que as universidades e suas comunidades poderiam desenvolver fontes de matéria-prima para tais processos de extração e, portanto, merecem atenção para a criação de pontos de coleta e parcerias. Nesse contexto, é necessário entender o comportamento dessa comunidade em relação à aquisição, armazenamento e descarte de equipamentos eletrônicos, bem como informações sobre temas relacionados ao gerenciamento e reciclagem de resíduos eletrônicos. Adicionalmente, criou-se uma rota conceitual de tratamento, a partir da integração de tecnologias descritas na literatura. Após a criação do design da rota, foi realizado um balanço de massa e energia, considerando dois casos base de fonte de placas de circuito impresso como matéria prima matéria prima: A) Lixo eletrônico em geral; B) utilizando somente celulares. Para ambos os casos, foi considerado o tratamento de 2 t/h. Determinou-se que o grupo estudado possui mais de 16,96 milhões de telefones celulares em hibernação, além de outros equipamentos, com valor de estoque estimado em 67,45 milhões de dólares para o grupo estudado na região metropolitana do Rio de Janeiro. Se extrapolado para todo o Brasil, pode chegar a 797,50 milhões de dólares para o grupo estudado. uma taxa interna de retorno de 141,6 por cento e 3990,7 por cento para o caso A e B, respectivamente e valor presente líquido de USD 44,834,616 e USD 3,215,300,083 para o caso A e B, respectivamente. Adicionalmente, foi determinado que o caso A possui uma grande sensibilidade a variação da taxa de ocupação. Neste contexto, a presente pesquisa tem o potencial de ajudar na criação da primeira planta industrial brasileira voltada para a reciclagem de placas de circuito impresso, assim como entender quais são as variáveis chaves para o processamento destes componentes. Adicionalmente, o projeto apresenta o investimento necessário para a criação da planta, sendo uma informação crucial para potenciais investidores. / [en] Brazil is the second largest producer of electronic waste in the Americas, with a production that grows each year and only 10 percent of it is properly treated. Additionally, Brazil does not have its own technology for treating printed circuit boards, a key component present in this type of waste. Currently, Brazil does not have an industrial plant dedicated to this extractive activity from electronic waste, with most of its treatment carried out abroad. The research hypothesis of this manuscript is that universities and their communities could develop raw material sources for such extraction processes and, therefore, deserve attention for the creation of collection points and partnerships. In this context, it is necessary to understand the behavior of this community in relation to the acquisition, storage and disposal of electronic equipment, as well as information on issues related to the management and recycling of electronic waste. Additionally, a conceptual treatment route was created based on the integration of technologies described in the literature. After creating the route design, a mass and energy balance was carried out, considering two base cases of printed circuit boards as raw material: A) Electronic waste in general; B) using cell phones only. For both cases, the treatment of 2 t/h was considered. It was determined that the studied group has more than 16.96 million cell phones in hibernation, in addition to other equipment, with an estimated inventory value of 67.45 million dollars for the studied group in the metropolitan region of Rio de Janeiro. If extrapolated to all of Brazil, it could reach 797.50 million dollars for the studied group. an internal rate of return of 141.6 percent and 3990.7 percent for case A and B, respectively, and net present value of USD 44,834,616 and USD 3,215,300,083 for case A and B, respectively. Additionally, it was determined that case A is highly sensitive to occupancy rate variation. In this context, this research has the potential to help in the creation of the first Brazilian industrial plant dedicated to the recycling of printed circuit boards, as well as to understand the key variables for the processing of these components. Additionally, the project presents the investment necessary for the creation of the plant, being crucial information for potential investors.

The fashion industry is one of the most heavily polluting industries in the world. The industry has traditionally operated through the linear economy utilizing a take-make-waste supply chain. The appearance of the circular economy has provided the fashion industry with the opportunity to change its business models to more circular alternatives. However, focusing mainly on improving operations and forecasting models in ways for prevention, previous research has not considered the role of unsold goods (or deadstock) in a circular economy. This study contributes to the literature on the circular economy through insight into how deadstock can be reduced using circular strategies. Using an abductive approach, a case study was made on a fashion company that is investigating the possibilities to reduce deadstock using circular strategies. The study combines findings from previous research with a thematic analysis based on data collected from interviews with managers and experts working at the case company to answer the proposed research questions and fulfill its purpose. The findings of the study show that the drivers of and barriers to circular strategies at the case company seem to correspond with previous research. The drivers seem to mainly be softer powers that encourage change, such as organization and culture, while the barriers tend to be harder powers that hinder the change, such as heavy investments and the need for technological advancement. Moreover, the company lacks drivers being hard powers, such as technology and financial incentives. The authors, therefore, argue that the lack of drivers forcing change is one of the reasons why the industry has not changed more yet. Additionally, deadstock reducing initiatives seem to share many similarities in drivers and barriers with circular strategies, the main difference being an attitudinal difference towards them. This spurs a discussion of the duality of Doing Good and Doing Right in sustainability efforts where it is argued that to truly become sustainable, an organization must be able to do both. This study implies that deadstock reduction should be incorporated into the circular economy utilizing the circular strategies. More collaboration needs to happen between the individual circular strategies, for example through shared data systems, coordinated management for all circular strategies, and shared collecting and sorting systems. Furthermore, although soft powers encouraging change are in place, no significant transition towards circularity is to be expected in the fashion industry until hard powers, such as enabling technological innovations, are in place to force the change. / Modeindustrin är en av världens mest förorenande industrier. Industrin har traditionellt sett drivits av den linjära ekonomin och använt en ta-producera-släng värdekedja. Den cirkulära ekonomins uppkomst har gett modeindustrin möjligheten att ändra dess affärsmodeller till mer cirkulära alternativ. Dock, genom att fokusera mer på förbättringar av tekniker och prognosmodeller, så har tidigare forskning inte undersökt osålda varors (eller deadstock) roll i en cirkulär ekonomi. Den här studien bidrar till litteraturen inom cirkulär ekonomi genom att tillföra insikter om hur deadstock kan reduceras genom cirkulära strategier. Med en abduktivansats utfördes en fallstudie på ett företag som undersöker möjligheterna att reducera överlager genom cirkulära strategier. Studien kombinerar insikter från tidigare forskning med insikter från en tematisk analys gjort på data från intervjuer med chefer och experter på fallföretaget för att svara på de föreslagna forskningsfrågorna och uppfylla sitt syfte. Resultatet av studien visar att drivkrafterna och barriärerna för cirkulära strategier på fallföretaget överensstämmer med tidigare forskning. Drivkrafterna är huvudsakligen mjukare i karaktär och uppmuntrar till förändring, såsom organisation och kultur, medan barriärerna tenderar att vara av hårdare karaktär och stoppar förändring, så som stora investeringar och ett behov av teknologiskutveckling. Därtill saknar fallföretaget drivkrafter av hårdare karaktär, såsom teknologiska och finansiella incitament, med förmågan att kunna tvinga fram förändring. Författarna till denna studie argumenterar därför för att avsaknaden av tvingande drivkrafter är en av de starkaste anledningarna till att modeindustrin ännu inte förändrats med signifikant och blivit mer cirkulär. Vidare tycks deadstock-reducerande initiativ dela många likheter i drivkrafter och barriärer med de cirkulära strategierna medan den huvudsakliga skillnaden tycks ligga i attityden gentemot de olika strategierna. Detta sporrade en diskussion om dualiteten i att Göra Bra och att Göra Rätt i hållbarhetsarbeten där det, för att bli helt hållbar, argumenteras för att organisationer måste kunna göra både och. Implikationerna av studier är att deadstock reducering borde tas med i den cirkulära ekonomin genom cirkulära strategier. Fler samarbeten måste dessutom ske mellan de olika cirkulära strategierna genom, till exempel, delade datasystem, ett koordinerat styrorgan församtliga cirkulära strategier och delade insamling- och sorteringssystem. Slutligen konstateras det att trots att mjukare krafter som uppmuntrar till förändring redan är verksamma så förväntas ingen signifikant omställning mot cirkularitet inom industrin ske om inte hårdare krafter, som möjliggörande teknologiska innovationer, kommer på plats för att tvinga till förändring.

Today, circular economy is becoming more and more important to think about when developing new solutions, and considering the growing and aging population it may be extra important when it comes to the design of solutions for health care. This thesis aims at exploring how a digital health technology solution for incontinence care can be designed to contribute to a circular economy. In order to achieve the aim, a case study is performed with the intention to answer four different research questions. To gather data and information, the study also uses methods such as interviews, surveys, and a literature study. The first conclusion that can be drawn is that there are eight different circular design strategy categories, each category with a unique focus area, that are assessed to be suitable to investigate for the given purpose. Three examples of focus areas of these categories are to reuse resources, to influence the user behaviour, and to prolong the use phase for a solution somehow. Furthermore, the users and the production company are seen as the most significant actors for the studied digital health technology solution, and together they have ten important requests including needs regarding provision of knowledge, easily understandable solutions, and peace of mind to mention some. Based on the conclusions regarding circular design strategies and important requests, three concepts are developed which in different ways are assessed to contribute to both circularity and to fulfilling actor requests. One of the concepts focuses on prolonging the use of some components by providing an adapted cleaning kit to keep the components at a high hygienic standard. Another concept focuses on encouraging correct usage of the whole solution through giving the users personal statistics and notifications related to monetary and environmental costs. The last concept aims at providing a simple way to return reusable components to the company in order to enable reuse by another user. Finally, conclusions regarding positive and negative aspects of the three developed concepts are presented, focusing on attributes such as circularity and value creation. The thesis presents different ways regarding how circular design strategies can be applied to a digital health technology solution, which can inspire and aid organisations in their way towards providing solutions that are adapted to fit a circular economy.

Esta tesis de investigación tiene como finalidad la implementación de un modelo de gestión sostenible basado en la economía circular que permita el tratamiento y aprovechamiento del plástico PET en los colegios del Perú. El modelo parte debido a la necesidad de que exista un modelo de gestión que pueda ser aplicado a un escenario ya establecido como el distrito de Pachacamac ubicado en Lima-Perú. Debido a que este distrito tiene ciertas características de alta demanda en desechos plástico, se decidió la creación de un modelo ya que actualmente modelos en este tipo de distritos acá en Perú no existen. El modelo se basa en el uso de 3 Fases de gestión de residuos y viene apoyado de la metodología Lean y la economía circular, lo que le permite ser un modelo adaptable y cambiante de acuerdo con el escenario propuesto. Dentro de sus principales dimensiones se encuentran la cultura ambiental, la dimensión social y la dimensión económica lo que le permite ser un modelo integral. / This research thesis aims to implement a sustainable management model based on a circular economy that allows the treatment and use of PET plastic in schools in Peru. The research starts from the need of a management model to exist, this model can be applied to an already established scenario such as the district of Pachacamac located in Lima-Peru. Due to the fact that this district has a high demand in plastic waste, it was decided to create a new model since models of this kind do not exist currently in Peru, especially in districts like Pachacamac. The model proposed is based on the use of 3 phases of waste management and is supported by the Lean Methodology and Circular Economy, which allows it to be an adaptable and changing model according to the proposed scenario. This model starts from the use of 3 different dimensions that complement each other perfectly, this include the environmental culture, the social dimension and the economic dimension, which allows it to be an integral model. The model was applied in the district of Pachacamac in 3 different possible scenarios. In this way it was possible to conclude that the correct management of the 3 approaches of the model generates a high economic and environmental impact. Likewise, it was possible to help the population and its resources. / Tesis

Background: Functional sales has in recent years become increasingly debated among companies, as a result of increased interest in developing more sustainable strategies. Meanwhile, companies lack knowledge of what changes functional sales causes, particularly about what incentives, barriers and financial implications that affect the development and implementation of the business model. Since companies are not fully aware of what aspects to take into consideration before implementing functional sales, many companies hesitate on taking the step towards a more sustainable future. Research aim: The research aim of this study is to investigate underlying incentives and barriers that affect the development and implementation of functional sales within retail industry, but also what financial implications it causes. Moreover, this study aims to investigate how the conditions for an implementation of functional sales can be improved, by managing the incentives and barriers identified. Method: This study has been conducted with pragmatism as a scientific starting point. Moreover, an abductive approach has been used. The research design for this study is qualitative design, where a simple case study was selected through a targeted sampling of ”a typical case”. The respondents were selected through a snowball and a targeted sampling. The method used for conducting the analysis was a thematic analysis. Findings: The incentives identified in this study were environmental sustainability, meeting customer needs, closer connection to the customer and profitability. The barriers identified were increased requirements for product design, increased costs for warehousing, service and transportation, changes in cash flows, existing accounting principles and lack of profitability. In order to strengthen versus bridge these incentives and barriers, companies should take the following aspects into consideration: a well-adapted design, environmentally friendly and efficient transportation, ensure high inventory turnover rate, an adequate pricing, a well- formulated guarantee agreement and ensure financing. / Bakgrund: Funktionsförsäljning har på senare år blivit allt mer omdebatterat bland företag, till följd av att ökat intresse av att utveckla mer hållbara strategier. Samtidigt saknas forskning om vilka processer som förändras vid funktionsförsäljning, samt vilka incitament, hinder och finansiella implikationer som påverkar utveckling och implementeringen av affärsmodellen. I och med att företag inte är fullt medvetna om vilka aspekter de behöver ta i beaktning inför en implementering, tvekar företag att ta steget mot en mer hållbar framtid. Syfte: Denna studie syftar till att undersöka vilka bakomliggande incitament och hinder som påverkar utvecklingen och implementeringen av en cirkulär affärsmodell baserad på funktionsförsäljning inom detaljhandeln, samt vilka finansiella implikationer de ger upphov till. Vidare syftar studien till att undersöka hur förutsättningarna för en implementering av funktionsförsäljning kan förbättras, genom hantering av dessa incitament och hinder. Metod: Studien har genomförts med pragmatism som vetenskaplig utgångspunkt. Vidare har ett abduktivt angreppssätt använts. Studiens forskningsdesign är kvalitativ, där ett fallföretag valts ut genom ett målstyrt urval av ”ett typiskt fall”. Respondenterna valdes ut genom både ett snöbollsurval och ett målstyrt urval. Den analysmetod som studien har använts sig av är en så kallad tematisk analys. Slutsats: De incitament som identifierats i denna studie är miljömässig hållbarhet, möta kundens behov, komma närmare kund samt lönsamhet. De hinder som identifierats är ökade krav på produktdesign, ökade kostnader vid lagerhållning, service och transport, förändrade kassaflöden, befintliga redovisningsprinciper samt utebliven lönsamhet. För att förstärka respektive överbrygga dessa bör företag ta följande aspekter i beaktning: en anpassad design, miljövänliga och effektiva transporter, säkerställa hög lageromsättningshastighet, rätt prissättning, ett välformulerat garantiavtal samt säkerställa finansiering.

The amount of food packaging waste is one of the issues associated with increasing global population and corresponding increase in consumption rate of packaged foods. Traditional plastic food packaging derived from fossil fuels imposes a significant environmental threat. There are sustainable bio-based alternatives developed to substitute traditional plastic packaging that are implemented in circular economy business models. These solutions often utilise collaboration to be implemented, however, there is a lack of research on the collaborative processes that enable circular economy in bio-based food packaging. In this thesis we examine what collaborative processes are being used in the bio-based packaging supply chain and how these processes help with facilitating the implementation of circular economy in the packaging production. Moreover, this thesis also investigates what are the barriers that the packaging producers face as they collaborate toward a circular economy. Therefore, we use qualitative interviews with representatives of bio-based food packaging companies and study the theories of supply chain collaboration and circular economy such as resource based view, transaction cost economics and various iterations of circular supply chain management models. We find that bio-based food packaging producers collaborate externally with customers, suppliers and internally among organisational teams to enable the circular economy of bio-based alternatives to conventional plastics. We also find that collaboration for circular economy in bio-based food packaging solutions is challenged by cultural differences, varying regulations among countries, opportunistic behaviour across the supply chain, insufficient organisation of communication between collaborators as well and misalignment of their interests. We contribute empirical evidence of collaborative processes across bio-based food packaging supply chains providing a ground for further research streams across the aspects of collaboration for circular economy.

To this day, literature has mainly been focused on the implementation of Circular Economy in the business sector, but as more and more nations adopt the approach of Circular Economy there is a need to further research the role of public agencies in this transition. The City of Malmö is seen as a progressive actor in the field of climate issues and has integrated sustainability objectives widely across the entire organizational culture. However, behaviors and understandings of sustainability are not only connected to organizational culture, but also to organizational subculture. To successfully implement sustainable and circular practices in a public agency there is therefore a need to understand organizational subculture. To initiate the transition towards a circular economy, the municipality of Malmö procured a contract in 2019 that gave the departments of the city an opportunity to purchase circular furniture instead of new. On this foundation, the purpose of this paper was to qualitatively explore what possible subcultures that exist in the City of Malmö and how subcultures can influence circular purchasing practices within a public agency. Empirical data was gathered from semi-structured interviews, individual Organizational Culture Assessment Instrument surveys and strategic documents from five of Malmö’s departments. By analyzing the collected data from the theoretical lens of organizational culture, subculture and Competing Values Framework, this study reached three major findings. Firstly, the study indicates the existence of several organizational subcultures within the City of Malmö, that in various ways influence circular purchasing practices within the municipality. Secondly, circular purchasing is not only affected by subcultural values but also individual values and understandings of sustainability. Finally, multiple barriers and motivators for purchasing circular furniture were identified, where the main barrier shows a cultural and physical distance between the umbrella organization of the municipality and the departments. 2.12.0.0 / <p></p><p>2.12.0.0</p>
