Abstract [en]

Increased demands for circularity in manufacturing industry put pressure on transformation in order to meet the Sustainable Development Goals. Small-and-medium-sized-enterprises (SME)'s have an important role, supplying value chains with material and components for larger companies and original-equipment-manufacturers (OEMs). SME suppliers' net environmental footprint contributes to the OEM's overall footprint, however, SME suppliers are characterized by limited resources and competence to perform circularity activities. SME net environmental footprint consists of both production related targets combined with product related targets. Circular product performance evaluation have raised a demand for easy-to-use, self-assisting tools as a complement or substitute for standardised life-cycle-assessment (LCA) methods, often considered as costly with advanced calculations, and highlights the need for the development of accessible tools and guides that support the SMEs' circularity work. An established industrial tool based on previous research called the Green Performance Map (GPM), has successfully been used to assist circularity performance in production operations. This paper sets out to test the GPM tool in a new setting, addressing circularity in an extended value chain context, including three main areas; production and sourcing, product use and product end-of-life. The research presented is based on an in-depth case study with an interactive research approach and aims to explore how to reach a full value chain perspective on circularity in production. The result indicates that a joint and inclusive collaboration centred on the adapted GPM-tool, identifies and structures circular production principles as well as product use and end-of-life performance as a basis for evaluation. Findings from research study show that a comprehensive input-output tool could be used with limited competence and time, achieve increased employee awareness of circularity in the product value chain. This single case study brings a small empirical contribution to existing literature on SME circular production transformation, however it clearly shows on the urgency to evaluate circularity along the value chain in order to support a full industrial circular production transformation.

Abstract [en]

The manufacturing industry is searching for ways to reduce its use of natural resources but at the same time remain a business and be competitive. Production companies have seen the possibilities ofcircularity in production, which could bring new business opportunities when steering production towards closed-loop production systems. This licentiate thesis is focused on production operations, a central function in the production company that directly creates value for the customer in the manufacturing stage. Previous research shows that circularity could work as a strategy for the production company to reach the UN Sustainable Development goals. Previous research has focused on circularity in theproduct development stage and the design of production systems.However, little literature has focused on how established production operations practically change from their current linear production to a circular production. This licentiate thesis investigates how the production operation works with circularity transition today, and in what ways the production operation is supported to reach circularity goals. To address thementioned literature gap, research studies have been carried out by production companies in Sweden. Findings from the studies show similarities between the investigated companies regarding the scope and definition of the adopted circularity strategy, lack of clarified goals and lack of strategies in managing the production towards the anticipated direction. However, based on common circularity principles adopted from literature and managerial data generated from company interviews, themes and concepts were discovered that could give general recommendations anddirections for production companies to accelerate the transition from linear to circular production. The findings from the empirically driven investigations provide valuable insights into how circular transition couldbe managed in practice and which obstacles may arise and be overcome.The main contribution is three main aspects, circular production strategy, management systems and standards, which are identified as the enginethat in close connection with production operations drives the circularity transition. The practical contribution of this thesis addresses the lack of practical guidance on how manufacturing companies actually couldachieve circular production. 

Abstract [sv]

Tillverkningsindustrin söker nya vägar för att minska på sitt resursuttag men samtidigt bestå som företag och vara konkurrenskraftiga. Produktionsföretag har sett möjligheterna med cirkulär produktion. Nya affärsmöjligheter kan skapas genom att styra mot cirkularitetsmål. I fokus står produktionsverksamheten som direkt skapar värde för kund i tillverkningsskedet. Tidigare forskning visar på att cirkularitet kan vara en strategi för produktionsföretaget, särskilt i produktframtagning och i design av produktionssystem, för att nå målen om hållbar utveckling. Däremot finns det knappt någon forskning på hur en etablerad produktionsverksamhet gör för att ställa om från dagens läge till en cirkulär produktion. Den här licentiatavhandlingen undersöker hur produktionsverksamheten jobbar mot cirkularitet idag och hur verksamheten styrs för att nå cirkulära mål. För att adressera gapet mot tidigare forskning har forskningsstudier genomförts på produktionsföretag i Sverige. Resultat från studierna visar på likheter mellan de undersökta företagen när det gäller brist på omfattning och definition av den antagna cirkularitetsstrategin, brist på förtydligade mål och avsaknad av strategier för att leda produktionen i rätt riktning. Baserat på cirkularitetsprinciper som förekommer i litteraturen och information från företagsintervjuer, upptäcktes dock teman och koncept som kunde ge generella rekommendationer och riktning för produktionsföretagen till att påskynda övergången från linjär till cirkulär produktion. Resultaten från de empiriskt drivna undersökningarna ger värdefulla insikter om hur cirkulär övergång skulle kunna hanteras i praktiken och vilka hinder som kan uppstå och övervinnas. Det huvudsakliga bidraget med denna licentiatuppsats är de tre huvudaspekterna, cirkulär produktionsstrategi, ledningssystem och standarder som tillsammans med produktionsverksamheten driver den cirkulära transitionen. Det praktiska bidraget denna uppsats medför är välkommet då det saknas instruktioner till hur tillverkande företag faktiskt kan gå till väga för att nå en cirkulär produktion.
