In a very uncertain and competitive economy, companies have to cope with external constraints such as environmental and social issues, to gain competitive advantage. Over the last thirty years, numerous initiatives have appeared to deal with socio-environmental issues. However, contexts are complex and dynamics. Many authors therefore point out the need to establish a systemic perspective in order to improve the integration of sustainable issues into all company activities: from strategic decision-making to the end of the project. In addition, companies need to reinforce the relationship between general corporate development and eco-design activities. Based on literature review, this paper assumes that the integration of sustainability can be improved by developing a coherent and system approach between strategic, tactical and operational levels. The authors have chosen to demonstrate this assumption by targeting the environmental aspect of sustainability as a first step of their overall research. In this view, this paper proposes a navigation system composed of three modules: strategic, tactical and operational. This navigation system provides some pragmatic roadmaps for integrating environment into the company. Each module is linked to the others by the use of appropriate metrics. Bottom-up and top-down or middle-to-sides strategies are fully supported.To test this proposal, the navigation system is experimented retrospectively into an industrial process from the textile industry. The comparison between the initial situation and the experimental results allows authors to highlights potential environmental improvements. Some recommendations are made to challenges companies to use this navigation system, which argues in favor of environmental improvements.

Journal of Cleaner Production, Elsevier, 2012, 39 (January 2013 The growing number of tools and methods for environmental impact analysis shows the variety of contexts covered by ecodesign. As ecodesign tools are evolving rapidly and manipulating different data, environmental engineers are facing some difficulties to share data efficiently with the current product designers tools. To support this data exchange among software, the capacity of tools to interoperate has been widely improved over the last ten years by software integrations. However, this paper argues that the lack of dynamism and flexibility of those solutions cannot fully face the challenge of designing ecoeffective products. Therefore, this paper proposes a three-step method to build dynamic information exchanges between environmental engineers and product designers activities involved along the design process. This proposal can be adapted to the various ecodesign contexts encountered during the design process. It also gives the capacity to the environmental engineer to use any available information produced by other designers and to give them back an adapted answer to reiterate their choices. In this paper, the proposal has been tested on an industrial case study. The results are used to discuss the benefits of developing such a method in the industry to build a constant proactivity along the design process between the environmental engineer and product designers.

International audienceAdditive manufacturing is an innovative manufacturing process that enables rapid manufacturing of functional products and parts. On the other side, considering environmental aspects in design is beneficial as it leads to lower costs, improved product quality, new business opportunities. Thus, in order to foster the potential of AM in product innovation and product manufacturing in the light of environmental concerns, a new design method is necessary. This paper proposes a method in the context of Design with Additive Manufacturing, to take into account the specificities of this manufacturing process in a Design to Environment approach. The method is focused on the Early Design Stages (EDS) of the product development process, which are crucial not only for choices regarding the product characteristics but also for the environmental parameters that need to be taken into consideration. The implementation of the proposed method in creativity session of the EDS underlined the need for dedicated supports in terms of environmental decisions. More and specifically the need for providing tools to capitalize the decisions made focusing on each Life Cycle Stage of the product was identified as a requirement for this support

Effective collaboration between product designers and environmental experts is an important driver for the ecodesign practice in industry. This paper investigates the principal functions required for such an e ective collaboration and aims at facilitating them. Product designers should be able to integrate the environmental parameters into their activities, and to exchange information dynamically with the environmental expert whenever needed during the design process. Therefore, the IT system should be in itself dynamic and exible to the integration of new concepts (knowledge, software). Recent developments in Model Driven Engineering (MDE) are showing some interesting results to gain exibility and dynamism in the IT system. Combining software interoperability using model federation based on MDE with the speci city of ecodesign practice in industry this paper proposes the FESTivE method for Federate EcodeSign Tool modEls. Experimented in twodifferent industrial contexts the practical feasibility of FESTivE has been validated with practitioners. Results on the e ects of using FESTivE in industry shows that product designers and environmental experts are more equipped to anticipate and to respond to each other's needs at each stage of the design process of product or service.International audienceEffective collaboration between product designers and environmental experts is an important driver for the ecodesign practice in industry.

The emergence of additive manufacturing (AM) technologies, such as 3D printing and laser cutting, has created opportunities for new design practices covering a wide range of fields and a diversity of learning and teaching settings. The potential health impact of particulate matter and volatile organic compounds (VOCs) emitted from AM technologies is, therefore, a growing concern for makers. The research behind this paper addresses this issue by applying an indoor air quality assessment protocol in an educational fabrication laboratory. The paper presents the evaluation of the particle emission rate of different AM technologies. Real-time monitoring of multiple three-dimensional Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS) and Thermoplastic Elastomers (TPE) printers and Polymethyl methacrylate (PMMA) laser cutters was performed in different usage scenarios. Non-contact electrical detectors and off-line gas chromatography–mass spectrometry (GC-MS) were used to detect VOCs. The results show that the emitted particle surface area concentrations vary between 294 and 406.2 μm2/cm3 for three-dimensional printers, and between 55.06 and 92.3 μm2/cm3 for laser cutters. The experiments demonstrate that the emission concentrations were highly dependent on the filtration systems in place. The highest quantities of VOCs emitted included Cyclohexene and Benzyl Alcohol for PLA, ABS and TPE 3D printers, and formic acid and Xylene for PMMA laser cutters. The experiment concludes that signature emissions are detectable for a given material type and an AM technology pair. A suitable mitigation strategy can be specified for each signature detected. Finally, this paper outlines some guidelines for improving indoor air quality in such specific environments. The data provided, as well as the proposed indoor air quality protocol, can be used as a baseline for future studies, and thus help to determine whether the proposed strategies can enhance operator and bystander safety.
