The transition of existing food value chains towards greater sustainability is a societal imperative and a potential competitive factor. To succeed, some actors in the chains define new practices to establish common sustainability goals. To date, there is little evidence that the visions and values of the various actors in the chains have been leading to common solutions. This work explores the impact of collaboration on the value chain actors’ ability to jointly decide strategies for redesigning their activities. It reports on an empirical approach, which elicits the values and priorities of different stakeholders. The case takes place in the context of a value chain of the production/processing/sale of pork products. This value chain involves two French production-processing and redistribution cooperatives. Stakeholders were questioned about their prioritization of sustainability issues and these weights were applied to evaluate 12 animal feed solutions that vary in terms of the composition and geographical origin of rations, and the means and locations of their production. The results show that despite several years of cooperation, the objectives of the upstream and downstream actors remain different. The objectives of the upstream actors are driven by the economic difficulties of production and those of the downstream actors by the multiplicity of consumer demands and cost control objectives. In a reversal of the current practice marked by the economic difficulties of the actors upstream of the chain, an integrated culture could be led by bottom-up approaches to create a shared vision. Public policy would be then essential in regulating the sharing of value among actors; and in promoting chain models that help the required investments.

Sustainable supply chain management has received much attention from both academia and industry due to various issues such as economic stability, environment conservation, and social ethics. To improve the sustainable performance of a value chain, its members need to carefully select their suppliers in relation to their own strategy. Thus, an effective tool for sustainable supplier selection and evaluation is essential, which considers the triple bottom line (TBL) of economic, environmental and social aspects by means of criteria adapted to the situation analysed. This paper develops a fuzzy decision tool to evaluate the sustainable performance of suppliers according to TBL. Sustainability criteria are identified to take into account the real hotspots in a food value chain. The proposed model integrates triangular fuzzy numbers (TFN), AHP (Analytic Hierarchy Process) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) in a novel way to consider quantitative and qualitative criteria as well as objective and subjective data. This is missing in most existing research when building their fuzzy models for supplier selection, but critical in dealing with the heterogeneous data available for TBL assessment. The application in a sustainable agrifood value chain illustrates the effectiveness of the proposed tool.

This paper proposes a template to assist food value chain actors in their collaborative efforts to develop common sustainable strategies and business models. Inspired by the simplicity of the Business Model Canvas, the template reintroduces sustainable practices as a support for management solutions for sustainable food value chains. The template requires cooperation between actors and stakeholders and comprises three steps: (1) identification of needs for sustainability; (2) development of value chain practices aimed to deliver sustainable value, and assignment of responsibilities to actors for these practices; and (3) formulation of a sustainable value proposition. The template also allows a simple graphical representation of sustainability in value chains, which helps improve communication between actors, and allows stakeholders to be kept informed. The template is applied to a sustainable pork value chain to illustrate how it captures various aspects of sustainability in the pork industry.

There is a lack of standardized country-specific environmental data to combine with nutritional and dietary data for assessing the environmental impact of individual diets in epidemiology surveys, which are consequently reliant on environmental food datasets based on values retrieved from a heterogeneous literature. The aim of this study was to compare and assess the relative strengths and limits of a database of food greenhouse gas emissions (GHGE) values estimated with a hybrid method combining input/output and LCA approaches, with a dataset of GHGE values retrieved from the literature. France is the geographical perimeter considered in this study, but the methodology could be applied to other countries. The GHGE of 402 foodstuffs, representative of French diet, were estimated using the hybrid method. In parallel, the GHGE of individual foods were collected from existing literature. Median per-food-category GHGE values from the hybrid method and the reviewed literature were found to correlate strongly (Spearman correlation was 0.83), showing similar rankings of food categories. Median values were significantly different for only 5 (out of 29) food categories, including the ruminant meats category for which the hybrid method gave lower estimates than those from existing literature. Analysis also revealed that literature values came from heterogeneous studies that were not always sourced and that were conducted under different LCA modeling hypotheses. In contrast, the hybrid method helps build reliably-sourced, representative national standards for product-based datasets. We anticipate this hybrid method to be a starting point for better environmental impact assessments of diets.

International audienceReduction of packaging waste has been a European target for more than 40 years. However, packaging is indispensable for protecting what it carries. In this study, an analysis of the European regulations on packaging and of their resulting effect on recycling performance was performed by means of a literature survey and the national results published in the European Database, Eurostat. Based on these data, two series of five Life Cycle Assessments (corresponding to the national situation of five European countries: France, Germany, Italy, Spain, Sweden) were conducted on three olive packaging solutions: doypacks, glass jars and steel cans. The results highlight the influence of national household waste collection rates and selected technologies for waste treatment (recycling and incineration) on the environmental performance of packaging design. A qualitative analysis of user expectations by means of a questionnaire demonstrates that the environmentally better solution (doypack) was not aligned with user expectations. The loss of food introduced by the better packaging solution is also a reason to question its value. The authors conclude that it is important to increase waste collection rates and recycling in order to actually improve packaging sustainability. They also conclude that eco-design of packaging cannot be considered only in terms of the materials employed: the contribution of the consumers' behavior is also a determinant criterion in the design of food packaging

In a recycling scheme such as the recycling of End of Life Vehicle (ELV) materials, the different stakeholders are expected to configure the operation process and product distribution to maximize their own profits. In many cases, however, these individual optimizations do not correspond to the maximal profit for the whole chain. In addition, financial autonomy must be carefully studied and controlled so as to ensure an economically viable recycling chain. This paper proposes a cost-benefit parameterized model for the ELV glazing recycling scheme, both for network configuration and material flow sizing. The model is mapped using real ground data from French industrial partners, and a linear programming technique is used to optimize the network for maximum profit. The sensitivity of this economic performance in different situations is analyzed by varying key variables of the model. Results show that, while the current glazing recycling situation is not economically viable, a national glazing recycling network could actually become beneficial for all stakeholders under certain conditions that are likely to appear in the near future. Several scenarios for the recycling network are simulated to determine the best practices for each of the network scenarios.

International audienceThe practice of eco-design requires relating traditional design criteria to new environmental criteria. So far, few studies have investigated the nature and singularities of eco-design. This article provides some elements of response based upon the redesign of a consumer product (disposable razor). The study was conducted by three groups of experienced eco-designers using existing eco-design tools (SIMAPRO, ECOFAIRE, ECODESIGN PILOT). A protocol analysis with a three-level coding of transactions was carried out for this purpose. Two main findings are reported: (1) environmental assessment, solution finding and strategy definition are the activities which differentiate eco-design from design; (2) environmental initial assessment and strategy definition are more heavily influenced by eco-designers’ expertise than support from tools.Highlights► This study investigates the nature and singularities of eco-design compared to traditional design. ► A protocol analysis based on the observation of three experienced eco-designers' teams is conducted. ► Each team implements a different existing eco-design tool to redesign the same consumer product. ► Environmental assessment, solution finding and strategy definition appear to be specific to eco-design practice. ► Initial environmental assessment and strategy definition are heavily influenced by eco-designers' expertise

For a growing number of firms, it is important that life-cycle assessments (LCAs) as well as the interpretation of the results obtained be carried out directly by the design teams. Unfortunately, the complexity of these two elements hinders the development of really eco-designed products. In this paper, we propose a generic approach allowing a company to develop a specific environmental assessment tool which enables designers to carry out simplified environmental assessments during the design process. To be more precise, the generic approach is based on the creation of two main features: impact functions to simplify the inherent complexity of LCAs and an environmental categorisation per product range to facilitate the use of environmental assessment results by the design team. This paper presents the development of such tool (named EcoT) in the context of automotive part suppliers and demonstrates its technical robustness on two case studies (dashboards and door panels). At the end of the paper, we discuss the usability and appropriability of the EcoT tool based on handling tests carried out by the company design team.

The purpose of this article is to consider a new way of understanding the usefulness of products in the globalised society and to explain a new approach to designing in industrial organisations. To do this, we shall present two current trends in the field of design, namely, the continuous functional enhancement that products undergo and the inescapable segmentation that is at work in production procedures. We shall analyse the harm arising for the environment from these two trends using three concrete examples (the office chair, the Cathode Ray Tube (CRT) and the automated washing machine system) and will thus show the incompatibility of these trends with the concept of sustainable development. These three studies will lead us finally to suggest the need to commit to a change in the pattern of activity involving design based on the modification of four principles.

Despite the progressive use of ecodesign in the industrial world, taking into account environmental constraints remains problematical for small and medium sized enterprises (SMEs), which seem to be remaining on the fringe of the movement. Beyond the lack of environmental culture in the enterprises, the problem stems from the ecodesign tools which have not been designed with any thought of integrating them into the enterprises' organisation. There is indeed no method for ecodesign integration in companies. We show in this article that, while in fact there is a thorough and varied set of ecodesign tools available, they will not allow ecodesign to become more widespread while they remain tools for experts. We are therefore putting forward a method to carry out the integration of ecodesign in SMEs during demonstration projects implemented with the assistance of advisory centres specialised in the industrial sector of the company.
