In this study, the standpoints and visions of two consecutive classes of engineering students – following the...

A refrigerant system (like that of a supermarket) is a complex system if we consider all the stakeholders throughout its lifecycle phases (use, maintenance, technological update, end of life). The lack of stakeholders' interaction during the design and other lifecycle stages of such a system generates issues and leads to sub-optimal system performa...

Feature of the article "Closing the loop on platinum from catalytic converters: Contributions from material flow analysis and circularity indicators" (Journal of Industrial Ecology, 23(5), 1143-1158) in Science for Environment Policy, European Commission DG Environment News Alert Service.

Around 40% of the platinum used in EU catalytic converters is not recovered for recycling and is therefore ‘lost’ forever, indicates a new study. A more circular economy for platinum is essential to reduce imports of this critical raw material to the EU and minimise its damaging effects on the environment, the researchers argue. Better collection s...

Taking into consideration all the life cycle of a product is now an important step in the design of a product or a technology. Despite the improvement in refrigerant regulation, the environmental impacts of refrigeration systems remain important and need to be improved. In this paper, the environmental impacts of refrigeration systems in a typical...

In response to the growing development of a wide variety of circularity indicators (c-indicators), a taxonomy has been developed to gain clarity about their focuses, purposes and possible usages (e.g., benchmarking several circular economy business models, comparing two product designs on their potential circularity performance). The advisor linked...

The purpose of this paper is to develop and discuss a framework aiming at monitoring and optimizing the circularity performance of products for ensuring and facilitating green profit design trade-offs whilst meeting or anticipating end-of-life regulations during the design and development process of industrial products. The proposed framework is us...

Yet, evaluating the circularity potential of products during (re)design and development phases is a challenging task. In this study, several C-indicators are experienced by doctoral students and industrialists through two workshops on a real-w...

Societies are challenged worldwide to maintain or improve the life of an ageing population. In the meantime, it is an opportunity for businesses to develop products and services for the elderly. Participatory design - or co-design - promotes not only to design for, but also with and by older adults. Current studies tend to emphasize more field inve...

In this article, we try to map the Radical Innovation Design (RID) methodology in Gero’s Function-Behavior-Structure (FBS) framework. We encounter difficulties in doi...

Experimentation and validation tests, in the context of technology startups, are often costly, time-consuming, and, above all, not well organized. A review of the literature shows that existing tools and methods are either oriented towards lean iterative tests or strongly focused on technology improvement. There is therefore a gap to bridge by prov...

Over 50 sets of circularity indicators – created and used by academia, consulting companies and governmental agencies worldwide – have been reviewed and classified into a need-based taxonomy driven by the usage of such indicators. A query tool associated to the proposed taxonomy databank – using MS Excel with macros – has been designed to help iden...

With 270 million light vehicles and 20 million heavy-duty and off-road (HDOR) vehicles in use in the European Union, automotive and HDOR industries are two major sectors in the European economy. Each year, 12 million light vehicles plus 1 million HDOR vehicles reach their end-of-life. In a context of circular economy, following questions are of gro...

Life Cycle Assessment (LCA) assesses the environmental performance of products through their entire life cycle.

Industrial practitioners are increasingly willing to shift their products and businesses into more circular models. Circular economy paradigm requires optimization of system rather than components. Yet, existing methods and tools, intended to designers, engineers or managers, to assess and improve products' circularity potential are both lacking sy...

Companies make substantial R&D investments in early design stages to develop radically innovative products. However, despite abundant research work in the field of human-centered design, the front end of innovation is the least well-structured part of the innovation process. Radical Innovation Design (RID) methodology has put forward a structured p...

The issue of recovering platinum from catalytic converter of heavy vehicles, arises for economic (high valuable component due to the non-negligible presence of platinum that costs around 30 €/g), environmental (low platinum concentration in mines (below 10 g/t) required large consumption of energy), social (ore mining conditions are increasingly dr...

A great deal of work has been done to characterize entire sets of ideation indicators as well as isolated factors of innovativeness. Nevertheless, entire sets of innovativeness indicators are essential in business innovation competitions, as well as within companies in order to select promising innovative project seeds. In this paper, a complete se...

The French network Eco-design of Sustainable Systems (EcoSD) has initiated collaborative research projects in order to foster collaborations between academic and industrial partners. Two projects concerning eco-innovation processes, methods and tools have been carried out between 2012 and 2014. This paper first offers a synthesis of the projects, a...

Ambitious building retrofits are often hardly justified by energy savings only. A previous research project has shown that dividing by two the energy consumption of a building (like a school) may lead to a return on investment superior to 25 years [RS4E, 2010]. In this configuration, decision-makers are often not inclined to invest. Thus there is a...

This paper aims at investigating, through several examples of innovative startups, different categories of Urban-Centered Innovative (UrCI) design solutions as well as the necessity to conduct real life experimentations supported by public and private stakeholders. This research will also shed light on the reasons why some urban-centered innovation...

In this paper, the importance of problem setting in front end of innovation to radically innovate is emphasized prior to the use of the BMC.

In this respect, the City of Paris has implemented an experimentation mechanism to help innovative start-ups improving their solutions an...

In early eco-innovation phases, design teams need to assess the environmental relevance of ideas, and consequently, the evaluation stage becoMES even more critical, subjective and uncertain than in traditional design. This paper tackles the following question "How to turn elementary ideas into concepts with a high environmental potential in a desig...

Life Cycle Assessment (LCA) is a methodology to assess environmental performances of products throughout their life cycles. Traditionally, LCA-based decision-making focuses on environmental impacts, excluding customer expectations and economic considerations. Moreover, it usually uses generic data while environmental performances of industrial syst...

This paper aimed at defining the features and goals of eco-innovation compared to eco-design in industry. Both academic and normative approaches have difficulties establishing sharp boundaries (. That is why) as shown by a survey conducted with 12 French industrial organizations (was conducted. Results confirm this ambiguity). As an emerging topic,...

Purpose This paper considers the variabilities that exist in the exploitation of a complex industrial system. Our scenario-based LCA model ensures the reliability of results in situations where the system life cycle is very uncertain, where there is substantial lack of data, and/or where time and resources available are limited. It is also an effec...
