Product-Service systems (PSS) have been discussed as promising business strategies towards a circular economy (CE). However, PSS solutions are not necessarily more sustainable. PSS lifecycle management may play an important role to improve the offering and achieve sustainability benefits. Nevertheless, bottom-up issues for CE implementation in the industry such as lifecycle management are still little discussed in the literature. In this sense, this paper aims to explore a PSS business strategy adopted by a large white goods manufacturer that transitioned from a linear to a circular business, and the practices applied throughout the entire lifecycle that may be valuable to achieve CE requirements. A case-based approach was employed in this study and multiple sources of evidence were considered. Data were analyzed in the light of the literature, considering an inductive approach. The main preliminary findings suggest that resources consumption reduction and cost savings can be obtained through lifecycle management practices that take into consideration CE issues since the beginning of life of the PSS offering. Design practices, the adoption of different strategies at the end of life (reuse/remanufacturing or recycle), and the implementation of cleaner production practices are some of the identified practices that can contribute to achieve resource efficiency and CE requirements. This is a work in progress and further work is going to focus on a quantitative analysis of the environmental and economic performance of this PSS. In addition, as this study focused on a use-oriented PSS, future research may compare lifecycle management practices adopted by other and distinct PSS categories, and how different lifecycle management practices may contribute to achieving resource efficiency.

The potential for sustainability has been highlighted as one of the most important characteristics of product-service systems (PSS). Nevertheless, a PSS is not intrinsically sustainable. Methods and tools for PSS sustainability assessment should be developed to be integrated into the design process, especially in the early design phases, in order to conceive sustainable solutions. In addition, a PSS should be planned considering the three sustainability dimensions, from a life cycle perspective. However, PSS design and assessment considering the full life cycle is scarcely addressed in the literature, especially concerning the social dimension of sustainability. In this sense, this study proposes a streamlined life cycle assessment based approach to identify potential social impacts along the PSS life cycle that can be integrated into the early PSS design stages. The proposal is based on a hotspot analysis, which identifies where in the life cycle the most significant issues may occur. The proposal was developed in three main phases, anchored in both hotspots analysis and PSS literature. After developing it, 10 experts in PSS and sustainability assessed the proposal strengths and weakness. Some suggestions were offered by the researchers and improvements were introduced to the proposal regarding PSS life cycle phases and the social impact subcategories. The experts considered the hotspot analysis suitable to be applied in the early design stages when there is not much information yet regarding the system to conduct a complete life cycle assessment. The next step of this research is the proposal assessment by practitioners in industry. Further work will also integrate the environmental dimension of sustainability into the proposal.

This paper aims at exploring how some factors identified in the PSS and product/service innovation literature can hinder or foster sustainable PSS implementation in developing countries, since there is a lack of knowledge concerning the characteristics of PSS transition processes in different contexts. The identified factors were investigated empirically, through two PSS solutions located in an emerging economy. The main results demonstrated the role of some potential factors in supporting the implementation and diffusion of PSS solutions, especially those related to the involvement of multiple actors in the value creation and the social embeddedness. However, the role of those factors still need to be investigated in future works, since only two cases were analyzed in this research. Analyses of successful and unsuccessful PSS cases as well as the identification of other factors and characteristics of PSS implementation in different contexts are directions for further research.
