Item Open Access How does servitisation affect supply chain circularity? – A systematic literature review(Emerald, 2019-09-13) Kühl, Carl; Bourlakis, Michael; Aktas, Emel; Skipworth, HeatherPurpose The purpose of this paper is to test the link between servitisation and circular economy by synthesising the effect of product-service systems (PSS) on supply chain circularity (SCC). Design/methodology/approach Following a systematic literature review methodology, the study identified 67 studies and synthesised them using content analysis. Findings A conceptual model is developed illustrating how PSS business models impact SCC through increased product longevity, closure of resource loops and resource efficiency. It also identifies six contextual factors affecting the implementation of SCC including: economic attractiveness of SCC; firm sustainability strategy; policy and societal environment; product category; supply chain relationships; and technology. Research limitations/implications The conceptual model proposes that SCC increases with servitisation. It also proposes that the main circularity effect stems from increased product longevity, followed by closed resource loops and finally resource efficiency. The model is deduced from the literature by using secondary data. Practical implications The review provides practitioners with a framework to increase SCC through PSS business models. It also gives insight into the various contextual factors that may affect how a manufacturer’s servitisation strategy contributes to SCC. Originality/value This review contributes to the understanding of the relationship between servitisation and SCC by synthesising the different effects that exist. Moreover, it creates new knowledge by identifying a range of contextual factors affecting the relationship between PSS and SCC.Item Open Access Product-service systems and circular supply chain practices in UK SMEs: The moderating effect of internal environmental orientation(Elsevier, 2022-03-31) Kühl, Carl; Bourlakis, Michael; Aktas, Emel; Skipworth, HeatherMany studies uphold product-service systems (PSSs) as key factors for the implementation of circular supply chain (CSC) practices. This paper explores this assumption by testing the links between product-, use- and result-oriented PSSs and slowing, closing, and narrowing CSC practices. It develops and validates survey items that can be used to benchmark CSC practice implementation. In addition, it tests a model that recognises the positive moderating role of internal environmental orientation. A survey is conducted with 114 manufacturing small and medium-sized enterprises (SMEs) in the United Kingdom (UK). Partial least squares structural equation modelling is conducted to evaluate two models. The results show that product-oriented PSSs positively affect the slowing, use-oriented positively affects the closing, and result-oriented positively affects the slowing and the narrowing of resource loops. Internal environmental orientation does not moderate the PSS – CSC relationship, suggesting that less internally environmentally oriented firms are not at a disadvantage.
