Textil- och modeindustrin är en av de mest miljöförorenande industrierna i världen, med dess resursintensitet och stora mängd producerat avfall. De senaste åren, med start från år 2000 har klädproduktionen fördubblats, medan det genomsnittliga antalet gånger plagget används innan det slängs har minskat. Förändringar i produktionsteknik, konsumtionsmönster och materialval är sannolikt inte tillräckligt för att vända textilindustrins påverkan på miljön. Branschen behöver övergå från den nuvarande linjära ekonomin till en mer cirkulär ekonomi där design spelar en central roll. Denna studie belyser de svenska modeföretagens arbete med cirkulära designstrategier och utforskar hur kunskap om cirkulära strategier från andra branscher skulle kunna hjälpa modebranchen att gå mot ökad cirkularitet. Med hjälp av mixed method undersöktes den svenska modebranschens arbete med cirkulära design strategier och branschens utmaningar för ökad cirkularitet. Studien utforskade även organisationer utanför modebranschen för att avgöra hur deras cirkulära framgångar kan implementeras på modeindustrin. Resultaten visar att medan svenska modeföretag implementerar cirkulära designstrategier regelbundet behöver det inte översättas till ökad total cirkulariteten i deras kollektioner. Studien finner att ett gemensamt mått på cirkularitet inom modeprodukter, en systemförändring där cirkulär design och affärsmodeller implementeras genom hela värdekedjan, och ökat samarbete kombinerat med nödvändig infrastruktur är de mest nödvändiga faktorerna för att öka cirkulariteten inom branschen. / The textile and fashion industry is one of the most environmentally polluting industries in the world, with its resource intensity and large amount of produced waste. In recent years, starting from the year 2000, clothing production has doubled, while the average number of times a garment is used before it is thrown away has decreased. Changes in production technologies, consumption patterns and material choices are likely not, enough to reverse the textile industry's impact on the environment. The industry needs to shift from the current linear economy to a more circular one where design plays a pivotal role. This study sheds light on the Swedish fashion companie's work with circular design strategies and explores how knowledge about circular strategies gained from other industries could help fashion move towards increased circularity. With help of mixed method research the Swedish fashion industry's work with circular design strategies and the industry's challenges for increased circularity were examined. The study also explored organizations outside the fashion industry to determine how their circular successes can be implemented here. The results show that while Swedish fashion companies implement circular design strategies regularly it doesn’t necessary translate into increased overall circularity of their collections. The study finds that a common measure for circularity in fashion products, a systemic change where circular design and business models are implemented throughout the entire value chain, and increased collaboration paired with necessary infrastructure are the most necessary factors to increase circularity within the industry.

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.
