Ecodesign methods focused on remanufacturing

Understanding the product's ‘end-of-life’ is important to reduce the environmental impact of the products' final disposal. When the initial stages of product development consider end-of-life aspects, which can be established by ecodesign (a proactive approach of environmental management that aims to reduce the total environmental impact of products), it becomes easier to close the loop of materials. The ‘end-of-life’ ecodesign methods generally include more than one ‘end-of-life’ strategy. Since product complexity varies substantially, some components, systems or sub-systems are easier to be recycled, reused or remanufactured than others. Remanufacture is an effective way to maintain products in a closed-loop, reducing both environmental impacts and costs of the manufacturing processes. This paper presents some ecodesign methods focused on the integration of different ‘end-of-life’ strategies, with special attention to remanufacturing, given its increasing importance in the international scenario to reduce the life cycle impacts of products.     

Paving the way for the ISO 14006 ecodesign standard: an exploratory study in Spanish companies

A Spanish ecodesign standard (the UNE 150301) is being used as a basic reference point in paving the way for the future ISO 14006 ecodesign standard which may foreseeably be passed in 2011. This article aims to analyze the experience regarding adoption of the UNE 150301 in Spain.Following an analysis of the standard’s structure, its objectives and scope, its real implementation process is then analyzed based on an exploratory qualitative study carried out in four Spanish companies that have been pioneers in adopting this environmental standard. The conclusion is drawn in the article that in all the cases analyzed, the greatest source of impact occurs in the phase in which the product is used and is related to energy consumption. Companies appear to be satisfied with the adoption of this standard and, in particular, point out that they have managed to reduce the environmental impact of their products. However, they draw attention to the fact that, to deal with certain instances of impact that increases in cost entail, administrative bodies need to establish mandatory regulations, as environmentally-friendly companies would otherwise lose competitiveness.     

Integrating ecodesign by conducting changes in SMEs

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.     

Pollution prevention in China’s electroplating industry

Pollution prevention holds great promise for China as a strategy for curbing environmental degradation in the face of rapid industrial growth. This potential is demonstrated in the electroplating sector in China, where some firms are pursuing pollution prevention aggressively with results that include increased profits and significant cutbacks in pollution. We conducted research in four Chinese cities to investigate pollution prevention in the electroplating industry. Our study finds that firms with successful pollution prevention programs shared three main characteristics. First, they took a proactive approach towards cutting pollution. Proactive firms in our research employed pollution prevention as an overall environmental management strategy for their companies, and they possessed leaders and managers who demonstrated a strong commitment to pollution reduction goals and activities. Firms with successful pollution prevention programs also employed comprehensive environmental management systems. These systems assigned managers and workers responsibilities for pollution prevention through the use of rules, training, monitoring, and penalties and rewards. Finally, firms that undertook extensive pollution prevention measures employed staff with relatively high levels of technical knowledge and ability. Our results suggest that the aggressive adoption of pollution prevention by Chinese firms can help China address the widespread problems of inefficiency and poor management in Chinese firms, and the rapid spread of industrial pollution in rural areas.     

Environmental impact of the substitution of imported soybean meal with locally-produced rapeseed meal in dairy cow feed

Growing public concerns about the traceability, safety and environmental-friendliness of food products provide an incentive for shorter supply chains in agricultural production. Here, we assessed the environmental impacts of the substitution of imported soybean meal with locally-produced rapeseed meal in French dairy production systems, using a life-cycle approach. Two feeding rations based on either French-produced rapeseed meal or Brazilian-produced soy meal as concentrates, were compared for nine impact categories, including global warming, ecotoxicity and eutrophication. Crop production was the main contributor to most impacts, while overseas transport of soy meal only had a marginal effect. The “Soybean” ration appeared more environmentally-efficient than the “Rapeseed” ration because it involved less intensive management practices, in particular regarding synthetic fertilizers consumption. However, land use changes brought about by soybean cultivation should also be examined.     

Ecodesign of automotive components making use of natural jute fiber composites

Nowadays, the world faces unprecedented challenges in social, environmental and economical dimensions, in which the industrial design has showed an important contribution with solutions that provide positive answers regarding these problems. In particular, due to its relevance, the automotive industry confronts a moment of crises, and based on the ecodesign of products it has been transforming the challenges in opportunities. In this context, the use of natural fiber composites, produced in developing countries, have presented several social, environmental and economical advantages to design “green” automotive components. Thus, this work through LCA method demonstrates the possibility to use natural fibers through a case study design which investigates the environmental improvements related to the replacement of glass fibers for natural jute fibers, to produce a structural frontal bonnet of an off-road vehicle (Buggy). Results pointed out the advantages of applying jute fiber composites in Buggy enclosures.     

The value of adding design-for-the-environment to pollution prevention assistance options

The design stage of product development, recognized as key for determining costs and profitability, is also an unparalleled window of opportunity to champion the environment. During this early stage key materials, process, and energy source decisions determine the environmental impacts of a product for its entire life cycle. Integration of environmental factors into design is an emerging trend known as design-for-the-environment (DfE), ecodesign, or life-cycle design. From this perspective, designers gain inherent drivers for optimizing design and efficient use of resources. The intent of this article is to inspire expansion of pollution prevention assistance portfolio options to include DfE.     

Eco-efficiency and ecodesign in electrical and electronic products

Although it had been about 10 years since eco-efficiency and Factor X were proposed, these concepts were not actually utilized in companies. Accordingly, the author proposed eco-efficiency (Factor X) indicators and has actually utilized them since 2001 in companies, and has conducted many case studies of eco-efficiency and Factor X using these indicators. However, there remains an argument: the improvement of eco-efficiency (Factor X) is due to an improvement in functions and there is still a possibility that environmental impacts increase. So, this paper begins with a brief explanation of the proposed eco-efficiency (Factor X) indicators and the case studies. Next, eco-efficiency and ecodesign are discussed. This paper analyzes the relationship between functions and environmental impacts using results of quantitative evaluations and verifies the argument quantitatively. From this analysis result, the author found that most products improved the product's functions while reducing environmental impacts.     

Creating integrated business and environmental value within the context of China’s circular economy and ecological modernization

This paper investigates the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between economic growth and environmental stewardship in the context of China’s emerging ‘circular economy’ policy paradigm and based on ecological modernization theoretic approaches.Based on three company case studies in the information technology and electronic industries in China, we identify and demonstrate how a blended business and environmental value can be created from adopting a sustainable supply chain management approach. The adoption of a sustainable supply chain management approach is rapidly becoming a key business challenge and opportunity in China and other large emerging economies around the world, where our greatest environmental management challenges currently reside and will continue to exist for many years to come. The value creation framework proposed in research focuses on evaluating three case study companies who appear in various stages of an electronic industry supply chain. Value creation within a supply chain can provide the impetus for organizations to adopt circular economy, sustainable supply chain practices, for competitive reasons.In addition, we describe how a value proposition can be evaluated at two levels of analysis, a more specific micro-level and a more general meso-level of analysis. The four major business value dimensions include cost reduction, revenue generation, resiliency, and legitimacy and image.The initial findings are that a variety of opportunities exist for electronic firms in emerging and developing countries, while results from this study provide an important scholarly foundation to develop and refine sustainable supply chain management practices in emerging and developing economies.     

Assessment of the ecodesign improvement options using the global warming and economic performance indicators

In this paper, an assessment method is proposed for ecodesign improvement options using global warming and economic performance indicators. A reduction in the GHG emissions in the entire life cycle stages of a product was chosen as the global warming performance of the product. The external cost which converts the external effect of global warming into a monetary value was chosen as the global warming performance indicator in order to measure the performance of the GHG reduction of the product. The life cycle cost (LCC) of the product was chosen as the economic performance indicator to measure the performance of the life cycle cost reduction of the product. The assessment method based on the two performance indicators was applied to the liquid crystal display (LCD) panel for a case study.     

Quantifying producer and consumer-based eco-efficiencies for the identification of key ecodesign issues

We can find numerous case studies showing eco-efficiency being used as an analytical tool in ecodesign. But, all of these studies show that eco-efficiency being used only as an evaluation tool for design alternatives, not as a tool for the identification of key ecodesign issues. Here, we propose that producer-based eco-efficiency and consumer-based eco-efficiency can be used in identifying key ecodesign issues, which encompass not only the environmental aspects of a product, but also other aspects such as product quality and consumer satisfaction. The applicability of the proposed method was evaluated using 19 digital cameras. The results show that it is possible to identify weak points of a product in relation to the environment, product quality, and consumer satisfaction. Furthermore, it is possible to design a product that is environmentally friendly, while still maintaining a high level of quality and consumer satisfaction.     

Effects of the reduction of pollution emissions on the economic performance of firms: an empirical analysis focusing on demand and productivity

This paper analyzes whether the reduction of pollution emissions improves a firm’s economic performance through the increase in sales to environmentally conscious customers and the cost reductions associated with the improvement in productivity. Because the selection of the control (end-of-pipe) or prevention (cleaner production) approach differently influences the effect through the improvement in productivity, this is also considered. Using panel data for Japanese manufacturing firms over the period 2002–2008, the findings indicate that firms that have reduced their pollution emissions can increase their economic performance through the increase in demand for their products and an improvement in productivity. However, the latter is conditional, and so the prevention approach is preferred.     

Manufacturing actor’s LCA

Modern industrial environmental management encompasses life-cycle thinking. This entails considering not only the emissions and resource use of the company’s production processes, but also the environmental consequences of all processes related to a product’s life cycle. However, no single actor can influence the whole life cycle of a product. To be effective, analysis methods intended to support improvement actions should therefore also consider the decision makers’ power to influence.Regarding the life cycle of a product, there are at least as many perspectives on life-cycle thinking as there are actors. This paper presents an approach with which manufacturing decision makers can sharpen the focus in life-cycle assessment (LCA) from a conventional ‘products or services’ emphasis to a company’s manufacturing processes. The method has been developed by combining knowledge gained from earlier LCA studies with new empirical findings from an LCA study of an SKF manufacturing line.We demonstrate how system boundaries and functional units in an LCA can be defined when adding the perspective of a manufacturing decision maker to the product life-cycle perspective. Such analysis helps manufacturing decision makers identify improvement potentials in their spheres of influence, by focusing on the environmental consequences of energy and material losses in manufacturing rather than merely accounting for the contributions of individual stages of the life cycle to the overall environmental impact. The method identifies and directly relates the environmental consequences of emissions or raw material inputs in the product life cycle to manufacturing processes. In doing so, the holistic systems perspective in LCA is somewhat diminished in favor of the relevance of results to manufacturing decision makers.     

Alternative function fulfilment: incorporating environmental considerations into increased design space

The focal point of this paper is the relatively unknown concept of alternative function fulfilment (AFF), which is a design strategy that can be used to generate new ways of fulfilling a certain function and is referred to in the context of ecodesign. It can be considered an attractive environmental innovation strategy, provided that the increased design space is used to create more sustainable products and services.This paper explores the AFF concept and discusses the implications of adopting this concept. It thus focuses on how design and business processes may need to change to allow the radical shift towards AFF, in order to facilitate the envisaged significant environmental improvements.     

Transport of fish from Norway: energy analysis using industrial ecology as the framework

In this article, industrial ecology is used as a framework for analysing transport energy and its implication for products. The importance of the energy use for transport in a natural resource production system is analysed. By using fish as a case study, it is shown that the amount of energy for transport is highly dependent on the transport mode used. When applying industrial ecology principles for making assessments of the environmental impacts of products, the whole product chain is examined. This is an extended life-cycle approach, which also includes the transport of the finished products from the exporter to the importing country. This last part of the transport chain can be extremely energy demanding, as is shown for the case of fish transport. This finding has implications for the products, and for the form in which the products should be transported. Increasing the energy efficiency of production systems is an important industrial ecology principle, and must be taken into consideration when analysing product chains. A revision of today's practice of transporting large quantities of fresh whole fish by transcontinental airliners is bound to be necessary. This is a consequence of the demands for increased energy efficiency of tomorrow's industrial production systems.

Redesign of a component based on ecodesign practices: environmental impact and cost reduction achievements

This paper focuses on ecodesign and its application in the footwear industry aiming to identify how the ecodesign can be applied to the redesign of a shoe component in order to minimize the environmental impact and simultaneously reduce costs of production and assembling. The factors that influence the use of ecodesign, the benefits and the difficulties were also investigated. A longitudinal case study was developed in a company that produces shoe stiffeners. The process of ecodesign implementation and the practices of ecodesign considered during the product redesign were analyzed. A cost reduction of about 10% was observed (in relation to the use of natural fibers and polymers in its composition-31% of biomass and 69% of fossil material). Toxic materials were completely eliminated and a reduction of energy consumption was also noticed (during the injection process). The main contributions of this study are: ecodesign constructs to be further researched the conjoint analysis of technological ability and market potential in a redesign project, and the requirements to gain managerial support for a redesign project.     

Less bad is not good enough: approaching zero emissions techniques and systems

Radical changes towards sustainable products and a clean and safe system of production have yet to be developed and implemented in all sectors of industry. Technology holds the key to addressing many environmental problems and achieving sustainable patterns of economic growth. In many cases, companies already have the appropriate technological solution. However, the technology may not be in widespread use because of market and systemic failures and cultural barriers. Examples of market failures are the lack of information about cleaner technologies. Examples of systemic failures are weaknesses in linkages among firms, universities, research and development (R&D) institutions, and others involved in developing, supplying and applying technology. Cultural barriers are caused by the differences in the way companies communicate and do business. This makes “zero emissions” a much needed approach. The Journal of Cleaner Production has devoted this special issue to “Zero Emissions Techniques and Systems – ZETS” in the production and the urgent issues surrounding, “How to make sustainable companies become reality”. To document the state of the art in this field and to report progress are main goals of this issue. The objective of the planners of this special issue is to present perspectives, case studies and pedagogic initiatives from, academic, governmental, business, technical and financial sectors, as well as from NGOs from around the world.It is, however, evident that the term “zero emissions” still has different meanings and refers to different strategies and technologies. “Zero Emissions Techniques and Systems” are really a “SYSTEMS” aspect and not a sectoral approach. It develops more and more like a discussion about a mosaic. Some speak of the image they expect to be seen at the end, others speak of the tesserae they have to shape or the cement that fills the gaps between.     

Is selective abortion for a genetic disease an issue for the medical profession? A comparative study of Quebec and France

This article discusses the results of a study of the stand and attitudes of physicians from the Picardie, Nord-Pas-de-Calais region in France and the province of Quebec (Canada) regarding abortion following the diagnosis of a fetal anomaly by ultrasound, amniocentesis, or chorionic villus sampling. The study examined the degree of acceptability of abortion for several specific conditions as well as the physicians' perceptions of their role in the women's decision to abort. The study shows a consensus (over 75 per cent of the physicians surveyed) for aborting a fetus with trisomy 21. There is a similar consensus, except among Francophones in Quebec, for muscular dystrophy, cystic fibrosis, and Huntington disease. Conversely, there is no consensus (below 60 per cent) for several anomalies. In these cases, Quebec Anglophone physicians find abortion more acceptable than Quebec Francophone or French physicians. Concerning the role of the practitioners in the decision to abort, physicians in France tend to be much more directive than their overseas colleagues. Several hypotheses are suggested to explain the difference between the three groups surveyed.
