The recycling of OMC's carbon reinforcement by solvolysing thermoset matrix. A way of sustainability for composites.
Originally developed for high-tech applications, carbon ïŹbre/thermoset matrix composites have been increasingly used in leisure and sports industries, for several years. But the carbon reinforcement is the most expensive constituent, and also the most environmentally impacting in the elaboration of a composite part. To this day, no end-of-life solution or recycling process efficiently exists. This paper aims at demonstrating that recovering the carbon reinforcement is possible, technically and economically speaking. Moreover, it is particularly the basis for a life cycle analysis that assesses benefits and environmental challenges of this recycling loop based on the reinforcement recovery by a solvolysis of the organic matrix. Lastly, the lack of data to consider the better end-of-life option (reuse, recycling, energy recovery and material valorisation) will be underlined

Driving in the wrong lane: towards a longer life-span of cars
Within the context of product longevity, one especially impactful and ubiquitous product demands further research: the car. Car longevity has been addressed in the context of product life extension and product lifetime optimisation but there have been a few studies on car longevity in the context of business and none specifically from an industrial design context. This paper presents initial findings from preliminary interviews with key industry representatives such as car designers and engineers. It discusses the barriers to and opportunities for designing a car with a longer life-span. This and further data will later be analysed in order to produce a design framework to inform car
designers on life-span and usage optimization through design. Strategies such as increased longevity or use-intensity can potentially reduce the throughput - and thereafter the consumption - of cars. Such a shift in the automotive sector would support the transition from a linear economy to a more sustainable one. The initial findings, however, suggest that a longer life car is not an uncompromised solution and important concessions would have to be made in order to make this an acceptable

'Smart' design: greening the Total Product System
About the book: Since the Rio summit in 1992, the paradigm of corporate environmental responsibility has gradually and consistently extended beyond complying with increasingly stringent environmental regulation and taking up the proactive initiatives of a few world-class companies. Research indicates that the business and financial performance of companies may depend directly on socially and environmentally responsible business practices. Many world-class companies now realize that customers and other stakeholders do not distinguish between a company and its suppliers. As a result, greening the supply chain is an innovative idea which is fast gaining attention in the industry. Greening the Supply Chain is a compilation of important chapters written by a diverse set of international authors which incorporates a broad variety of perspectives.

Strategic perspectives on modularity
In this paper we argue that the debate on modularity has come to a point where a consensus is slowly emerging. However, we also contend that this consensus is clearly technology driven. In particular, no room is left for firm strategies. Typically, technology is considered as an exogenous variable to which firms have no choices but to adapt. Taking a slightly different perspective, our main objective is to offer a conceptual framework enabling to shed light on the role of corporate strategies in the process of modularization. From interviews with academic design engineers, we show that firms often consider product architecture as a critical variable to fit their strategic requirements. Based on design sciences, we build an original approach to product modularity. This approach, which leaves an important space for firms' strategic choices, proves also to seize a large part of the industrial reality of modularity. Our framework, which is a first step towards the consideration of strategies within the framework of modularity, gives an account for the diversity of industrial logics related to product modularization.product modularity ; corporate strategy ; technological determinism

A Total Product System Concept - a case study of the smart (tm) automobile
Increasing demand from consumers plus EU legislation has raised awareness within the automotive production sector of the urgent need to reduce the environmental impacts from the three main stages in vehicle life â car manufacture, car use and end-of life vehicle processing. The paper reviews how the originator and manufacturer of the smart automobile has worked directly with its main system partners to address environmental issues in these three stages while optimizing performance across the parameters of commercial viability. This required the creation of strategic relationships within the supply chain. Overall, this innovative approach is viewed in the context of a total product system. The smart car highlights the following critical areas: use of modularity in product design and production facility layout; emphasis on partner participation from product creation to after-sales; and the use of highly customised build-to-order product system to 'green' the entire supply chain. In particular, the case study compares the process characteristics empoyed at the smart car factory, called 'smartville', with more traditional approaches to vehicle manufacture. It exmaines these issues in a preliminary attempt to establish the actual or potential reduction of environmental impact in the three stages of vehicle life, including the role of main suppliers in this process
Concept And Exemplary Application Of Industrialized Re-Assembly To An Automotive Use Case In The Context Of Circular Economy
To reach set climate goals recent paradigms of production need to be reconsidered. Within the automotive industry, approaches like electric mobility focus on the use phase. However, the production of an electric car is resource and energy intensive, which diminishes the ecological advantage of electrification in the use phase. Established approaches aiming for the production phase often involve saving energy or resources, which is in a single-digit range when it comes to the reduction of emissions. In contrast to that, applying the concept of Circular Economy can reduce the ecological impact of products over their lifetime significantly. This paper introduces Re-Assembly as a plannable concept to extend the lifetime of products while reducing emissions and increasing the margins for the OEM. By combining the concept of Re-Assembly with other R-strategies, this paper aims to demonstrate the ecological and economic potential of circular business models, especially in the automotive sector. This is done by introducing the results of a use case and deriving specific enablers for the concept. The resulting enablers can be understood as fields of action for establishing Re-Assembly in practice
ReSICLED: a new recovery-conscious design method for complex products based on a multicriteria assessment of the recoverability
Significant improvements in end-of-life complex product recovery can be accomplished when recovery aspects are better integrated at the design stage of products. This paper introduces a new method that should allow design teams to produce better recovery-conscious designs, i.e. to integrate the complexity and the variability of recovery routes and to make recoverability more tangible to designers. The main methodological aspects of the new method are presented based on an analysis of the strengths and weaknesses of existing methods. In particular, the original multiprocess modelling of recovery scenarios and the original quantitative, multicriteria and multiscenario assessment of the recoverability of a product are detailed. On the basis of the assessment results, a design team is able to suggest design improvements. The implementation of the new method is simulated in real industrial practice. It is shown how the use of the method can bring significant gains in the productâs recoverability. Assets and drawbacks of the method are discussed.RĂ©gion RhĂŽne-Alpe
Sustainable product development in a circular economy: Implications for products, actors, decision-making support and lifecycle information management
The concept of circular economy (CE) is of great interest for manufacturing companies since it provides a framework which allows them to align organisational objectives with the Sustainable Development Goals (SDGs). Corporate CE entails the adoption of several value-retention options (R-strategies) throughout companiesâ operations, which aim at creating, preserving and recovering the value of assets and products. The sustainable product development (SPD) process, in which around 80% of the total environmental impact of a product is determined, is employed to translate R-strategies into new product requirements. This study is aimed at investigating the implications of R-strategy adoption for decision-making in SPD. The research follows an empirical approach, combining a literature review and in-depth semi-structured interviews with product developers and sustainability experts working in companies operating in the technical material cycles of the CE. Thus, implications for product dimensions, inter- and intraorganisational actors, decision-making support types and lifecycle information flows so that SPD processes further accommodate CE principles into products are investigated. This study reveals new directions to adjust the contextual factors of SPD to further align existing processes with widely expanding CE organisational cultures
