Is the Industrial Product-Service System Really Sustainable

As the product-service system has shifted from its original concept to the Industrial PSS, its scope has expanded to include industrial products. Furthermore, the overall goal of reducing environmental impacts has been left behind. Despite the PSS's potential as a business model for a more sustainable production and consumption system, the mere addition of services to conventional products does not necessarily lead to a reduction of environmental impacts. This paper aims to discuss the concepts related to PSS, the need for considering environmental impact reduction as a critical issue for sustainability, and the role of ecodesign practices in the development of PSS

Unveiling the dynamic complexity of rebound effects in sustainability transitions: Towards a system's perspective

Rebound effects (RE) are systemic responses to sustainability-oriented actions that have relentlessly offset the anticipated effects, hindering sustainability transitions. Limitations to account for feedback, delays, and non-linearities hinder a deep understanding of RE, leading to divergent magnitude estimates and management recommendations. Therefore, a better understanding of the dynamic complexity surrounding RE occurrence is needed. Dynamic complexity manifests from the feedback relationships between system elements and how they change over time. This work aims to enhance the understanding of RE's causal and dynamic traits, following system dynamics (SD) as the investigation frame. Based on a literature review, 24 RE-specific dynamic complexities were identified and further explored in case studies investigating RE through SD, which sustains three propositions for moving forward in RE investigations. This work sets the foundation for enabling less deterministic examinations of RE, capable of reaching recommendations that consider the true nature of the phenomenon

Integrating Eco-design and PLM in the Aviation Completion Industry: A Case Study

Part 5: Aeronautical and Automotive EngineeringInternational audienceAviation represents 12% of the CO2 emissions from all transport sources in the world. These pollutants are even stronger in their impact because they are released at high altitudes. Therefore, aeronautical companies have adopted the eco-design and PLM perspective to integrate the environmental concerns into the development of their products. PLM permits to include the environmental matters into every phase of the development process, not forgetting traditional arguments such as function, costs, production and aesthetics. Research regarding ecologically concerned textiles in aviation completion industry is not available in literature, especially those regarding its whole lifecycle and supply chain. Therefore, this paper aims to analyse this unexplored concern by assessing the integration of eco-design and PLM perspective for the use of textile materials in this industry sector. Through a case study, the research team explored the completion function of a north-American company in general and, specifically, the use of textile materials for internal completion of the aircraft. Even though representing 1% of the total weight of the aircraft, textiles represent an important factor in the composition of an airplane and the fact that it is being thought off as another recyclable and not disposable part of it should mean a shift in the perception of its growing importance in the development of the plane as a whole
