Abstract [en]

In the context of increasing pressure for sustainable production practices, this paper proposes a framework for how production companies could operationalise circular economy principles. The focus is on the production organisation, and how production operations could contribute to strategic circularity change. Prior research has used the Green kaizen methodology to identify environmental aspects and circularity related to the input-output flow of resources at the production shop floor. However, this paper finds that a more comprehensive approach is required, involving all levels of the production organisation. First, the paper defines circular production principles for production operations, showing that these principles vary across different company levels. Operations and shop floor level principles tend to be closer to the production input-output system, whereas factory management level principles are more focused on information sharing and internal and external relations. The circular production principles followed a hierarchical organisational structure with a bottom-up drive, where the allocation of organisational resources increased as the level of the hierarchy increased. The study reveals parallels with Likert's management system, where green kaizen activities are suitable for the shop floor level, but business development requires authority exploitation. Secondly, the paper identifies four circularity impact factors that apply to all company levels. These factors enhance the practical utility and implementation of circularity aspects, making them applicable to all levels of the company. The framework for bottom-up escalation of circular production principles can be used as a roadmap or support for managing a circularity bottom-up transition work. The findings presented in this paper fill a knowledge gap regarding the organisational and managerial work required for circular production. Specifically, this paper addresses challenges related to circular production management, including the gap between strategic targets and operational-driven work. By proposing a comprehensive framework for operationalising circular production principles, this paper offers practical guidance for production companies seeking to transition to circular economy practices.

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.
