This is the fifth Special Issue on Design and Manufacturing for Environmental Sustainability. The first Special Issue on this topic was issued in 2009, and the previous one was in 2018. The acceptance of sustainability has been increasing, as evidenced by the United Nations’ Sustainable Development Goals (SDGs), various carbon neutral movements, and, among others, the gradual recognition of potential impacts of the EU’s “Circular Economy,” which promotes circulation-based businesses to increase the employment and market competitiveness of the EU. This increase in acceptance has brought with it increased activity in the research area of design and manufacturing for environmental sustainability, with the result that this fifth Special Issue includes seventeen well-written papers, a significant increase over the six that appeared in the fourth. The first paper “Potential Impacts of the European Union’s Circular Economy Policy on Japanese Manufacturers” overviews the EU’s Circular Economy and points out key enabling technologies. To approach environmental sustainability, we should promote various technologies related to ecodesign, process technologies, business strategy, and digital technology. At the same time, we must focus on life cycle design and management, an indispensable technology which synthesizes a sustainable circulation system by integrating the technologies mentioned above. Accordingly, this Special Issue covers both aspects, with the seventeen manuscripts in it organized as follows. The first three papers, authored by Y. Umeda et al., K. Halada, and M. Kojima, give overviews and discuss requirements for technological development. The next two manuscripts by K. Fujimoto et al. and Y. Kikuchi et al. discuss modeling, simulation, and assessment of circulation systems. Papers six to eight, written by W.-H. Chung et al., S. Yamada et al., and K. Yoda et al. develop life cycle design methods. The remaining manuscripts advance fundamental technologies. Manuscripts nine to eleven, by R. Yonemoto et al., T. Samukawa et al., and Y. Yaguchi et al., deal with sustainable manufacturing. Finally, six manuscripts by C. Tokoro et al., K. Tsuji et al., A. Ogawa et al., A. Yoshimura et al., T. Hiruta et al., and S. Nasu et al. are about life cycle processes; recycling technologies and product use phase such as car sharing and maintenance. Most of the papers, revised and extended in response to the editor’s invitations, were originally presented at EcoDesign 2019: the 11th International Symposium on Environmentally Conscious Design and Inverse Manufacturing, held in Yokohama, Japan. The editor sincerely thanks the authors and reviewers for their devoted work in making this Special Issue possible. We hope that these articles will encourage further research into design and manufacturing for environmental sustainability.

This is the fourth special issue on design and manufacturing for environmental sustainability. While Japanese manufacturers are not so active in this field, the trend of integrating sustainability into manufacturing activities and management of companies is becoming dominant. We can point out three epoch-making instances: namely, United Nations’ ‘Sustainable Development Goals (SDGs),’ which consists of 17 goals to be achieved by 2030, covering not only environmental sustainability but also social and human sustainability; EU’s ‘Circular Economy,’ which promotes various routes for resource circulation (e.g., reuse, remanufacturing, maintenance, and recycling) for increasing employment and market competitiveness of EU and resource efficiency; and ‘Paris Agreement’ on climate change, which enforces reduction of the emission of greenhouse gases to zero by the end of this century. This special issue includes six well-written papers, all of which are deeply related to these three policies. The first four papers focus on product life cycle or even multiple product life cycles. This aspect is an inherent feature of design and manufacturing for environmental sustainability, which was not considered in traditional design and manufacturing. The keywords of these four papers are life cycle CO2 emission evaluation of electric vehicles, life cycle simulation of reuse among multiple product life cycles, disassembly part selection based on the idea of life expectancy, and personalization design aiming at avoiding mass production and mass disposal. The latter two papers are rather fresh in this journal. The fifth paper deals with customer preferences in Indonesia. Focusing on life styles in developing countries is a very important topic emphasized in SDGs. The last paper deals with food waste, which is emphasized in both SDGs and Circular Economy. Most of the papers, revised and extended in response to the editor’s invitations, were originally presented at EcoDesign 2017: the tenth International Symposium on Environmentally Conscious Design and Inverse Manufacturing, held in Tainan, Taiwan. The editor sincerely thanks the authors and reviewers for their devoted work in making this special issue possible. We hope that these articles will encourage further research on design and manufacturing for environmental sustainability.

This issue focuses on design and manufacturing theories and methodologies aimed at achieving environmental sustainability. It has been two decades since environmental sustainability and related issues have been discussed as main issues in design and manufacturing. In these 20 years, theories and methodologies have been developed on environmentally conscious design, including the design of disassembly and life cycle assessment, and manufacturing techniques for saving energy and resources and low emission. In spite of these efforts, the seriousness of the environmental issues, e.g., global warming, is getting harder and harder and new issues continuously arise. It has gradually been recognized that essential problems reside within the manufacturing industry structure and the center of the manufacturing industry has shifted from developed countries such as Japan and US to developing countries with accelerating mass production and mass consumption. Based on this recognition, this special issues deals with rather novel topics emerging in the domain of design and manufacturing for environmental sustainability. The first five papers provide a global scope on the relationship between environmental sustainability and manufacturing industry, including global energy consumption patterns, manufacturing industry scenario writing, informative reviews on lean remanufacturing, urban mining, and education on resource scarcity. The second three papers focus on human recognition and behavior – emerging topics in this domain – including socially responsible investment, customer choice, and the routing of electric vehicles. The last five papers propose new methods or technologies of environmentally conscious design and sustainable manufacturing, including ecobusiness design, electric vehicle heating systems, and the sustainability evaluation of manufacturing processes. Some papers, revised and extended in response to the editor’s invitations, were originally presented at EcoDesign 2013: 8th International Symposium on Environmentally Conscious Design and Inverse Manufacturing (Jeju, Korea). The editor sincerely thanks the authors and reviewers for their devoted work in making this special issue possible. We hope that these articles will encourage further research on design and manufacturing for environmental sustainability.

As the third special issue on Design and Manufacturing for Environmental Sustainability for IJAT, this issue focuses on design and manufacturing theories and methodologies for achieving environmental sustainability and the topic of the special issue seems to be becoming established in this journal. This special issue contains six articles consisting of a wide variety of rather novel topics emerging in the domain of design and manufacturing for environmental sustainability. The first three deal with design problem in the broader sense: designing of system of systems taking distributed energy generation systems, upgradable design problems, and selection problem of end-of-life products recovery options integrated from the view of environmental load and cost. The last three papers deal with manufacturing problems in the broader sense – motion extraction problems for disassembly automation, machine tool energy efficiency, and optimization problems related to machine tool operating conditions for increasing environmental sustainability. Some papers, revised and extended at the editor’s request, were presented originally at EcoDesign 2015, the ninth international symposium on environmentally conscious design and inverse manufacturing, held in Tokyo, Japan, 2015. The editor thanks the authors and reviewers for their comprehensive efforts in making this special issue possible and hopes these articles will encourage further research on design and manufacturing for environmental sustainability.

Assessments of availability and sustainability of metals necessary for economic development into the future are important for planning by producers, consumers, and governments. This work assessed the U.S. copper life cycle and examined six future scenarios by which to assess the circular economy and sustainability of copper to 2030. Regression analysis methodology was used to identify relationships among seven drivers and eight materials flows. These relationships were used to develop six forecasts of future scenarios for U.S. production, consumption, old scrap collection, new scrap recovery, landfilling, and scrap exports of copper. Flow forecasts were used to quantify circularity and environmental footprint metrics to assess sustainability. Results of the scenario analyses provide insights into the types of behaviors and trends that could be incentivized to allow for increased circularity of copper. One such finding was that slow population growth and high urbanization resulted in the most circular scenario. Major limitations to circularity are import reliance and scrap exports. Analysis of the scenarios leads to the conclusions that population dynamics are critical to the circularity of copper, as well as that both environmental footprint metrics and circularity indicators must be considered when assessing environmental sustainability.

Abstract Environmental issues, especially those related to the over-exploitation of natural resources, are leading towards considering alternative solutions and new approaches, such as the circular economy. Currently, some key elements of the circular economy approach are sustainable procurement of raw materials, improvement of production processes and ecological design, adoption of more sustainable distribution and consumption models, development of secondary raw material markets. This work aims to analyse the use of hemp as a building material, replacing traditional construction materials, but respecting at the same time the thermal, insulating and acoustic characteristics required in the construction of a building. The methodology used was Life Cycle Assessment (LCA), which considered the hemp cultivation phase and the production phase of hemp-lime (“hempcrete”) walls. The hempcrete product was compared with two different solutions: a hemp and lime block, and a traditional perforated brick block with external insulation in polystyrene. In particular, the differences among the products in terms of embodied energy and net CO2 emissions were analysed. Results showed that the hempcrete wall had better environmental performances than the other two solutions.

Abstract Purpose In a context where the transition to a circular economy is increasingly required, it is necessary to clarify the relationship between sustainability and circularity. In this commentary we summarise what are circularity indicators and what is LCA (Life Cycle Assessment), and we discuss their potential role in improving circular decision making. Methods Based on literature, a focus on how circularity indicators and LCA could be used in circular decision making is presented. Moreover, an analysis of recent studies has been carried out to identify the relationship between LCA and circularity indicators. Results and discussion We can state that no authors have concluded that circularity indicators can be used alone to choose the best option in circular economy projects. This is because the circularity indicators only provide a partial view on the environmental performance of a system. At the same time, it appears that the circularity indicators are easier to communicate, and a high degree of circularity could help to build good relationships with customers and increase reputation among stakeholders, as well as to have an easier access to funding. Conclusions and recommendations At the end, we propose a procedure to include both the LCA and the circularity measurement in the assessment of circular economy strategies. While still at an early stage of conceptualisation, it gives an idea on how to integrate environmental sustainability aspects into circular economy initiatives.
