Present and Future Sustainability Development of 3D Metal Printing
European Journal of Sustainable Development Research, 2021, 5(3), em0168, https://doi.org/10.21601/ejosdr/11132
ABSTRACT: Additive manufacturing (AM), also known as 3D printing is a relatively new concept and promising technology for industrial production. It is important to investigate the environmental impact of the AM process in light of the environmental critical situation of the Earth. The elimination of some costly prefabrication processes such as molding or post-fabrication stages such as machining and welding required in traditional manufacturing methods favor the AM process and provide beneficial economic advantages. Furthermore, the reduction of manufacturing steps contributes to environmental protection through fewer operations, less material, and energy consumption, and reduced transportation. This study is a review for the assessment of environmental impact and life cycle of some well-known AM technologies for manufacturing metallic parts and components. The fabrication of a pump impeller is simulated through a well-known metal production AM technology and casting process for direct comparison. Life Cycle Assessment (LCA) is applied to measure the environmental impact in five different stages of pump impeller lifetime with the two different fabrication processes. AM compared to casting has an environmental impact reduction potential of 15%, 20%, 65%, 20%, and 10% respectively in Global Warming Potential (GWP), Acidifications Potential (AP), Water Aquatic Eco-toxicity Potential (FAETP), Human Toxicity Potential (HTP), and Stratospheric Ozone Depletion (ODP). Using hydroelectricity and renewable electricity mitigate the environmental impact of the AM process in pre-manufacturing and manufacturing stages temporarily until the advancement of AM technology for consuming less energy. Recommendations for future research to enhance the environmental sustainability of the AM process is proposed as outcomes of this study.

Do Universities Contribute to Sustainable Development?
European Journal of Sustainable Development Research, 2020, 4(2), em0112, https://doi.org/10.29333/ejosdr/6429
ABSTRACT: Given the support of the global community of sustainable development, it is perhaps logical to infer that universities will be strong participants in the push to improve the sustainability of society in general, and among the leaders in efforts to achieve the United Nations Sustainable Development Goals (SDGs) for 2015-2030. To ascertain if this inference is valid, it can be instructive to examine and assess universities for their contributions to the SDGs. This has in fact already begun, with the launch of a new global university ranking of universities, aimed at measuring their contributions to the SDGs. Here we examine how universities contribute to sustainable development, and whether such rankings can motivate and drive initiatives that support sustainable development.

Advances in Sustainable Development Research
European Journal of Sustainable Development Research, 2019, 3(2), em0085, https://doi.org/10.29333/ejosdr/5730
ABSTRACT: The UN Sustainable Development Goals provide a framework for developing plans and policies for sustainable development, and have spurred an increase in research and activity in this field. There is no single approach to sustainable development, as approaches will vary from country to country, reflecting national and local needs and contexts. But care is needed in moving forward with the Sustainable Development Goals, if their benefits are to be realized. This issue of the European Journal of Sustainable Development Research marks its second anniversary, and demonstrates that the journal has already made a notable impact on the field of sustainable development through having published research on many recent advances.

Pro-environmental Printing Behaviour as an Indicator to Reduce Paper Cost at Work
European Journal of Sustainable Development Research, 2018, 2(3), 38, https://doi.org/10.20897/ejosdr/2670
ABSTRACT: Today we are facing environmental hitches such as deforestation and global warming, due to which atmospheric CO2 level has increased by 25% since 1850. It is human activities that have created these problems; hence, the resolutions to these encounters lie in behavioral change. Thus, it is only by empowering people that the environment can be protected. This study aims to explore reduction of printing at elementary schools by enhancing pro-environmental printing behavior. Literature review is presented in the following themes – demographic, impact of printing on the environment and pro-environmental printing behavior. An observation method is applied in this study and data is obtained from 108 teachers from seven elementary schools at three different regions in Northwest Friesland, The Netherlands by using digital print data and printers’ observation. The main findings illustrate that pro-environmental behaviour has a positive effect on the printing behavior. This research reveals that the experimental group printed 45% to 51% less during intervention. Therefore by extending pro environmental behaviour, financial and environmental costs can be minimized. This reading recommends directors of the schools to enhance pro-environmental printing behaviour among teachers to reduce both financial and environmental costs measured as use of paper.

Understanding the Sustainability of Fuel from the Viewpoint of Exergy
European Journal of Sustainable Development Research, 2018, 2(1), 09, https://doi.org/10.20897/ejosdr/76935
ABSTRACT: At the same time of providing a huge amount of energy to the world population (social sustainability) and global economy (economic sustainability), the fuel itself also releases a great amount of emissions to the environment the world people live in in the forms of gaseous pollutants (SOx, NOx, CO, CO2, CH4, etc.) and ash compositions (Al2O3, CaO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SO3, SiO2, TiO2, etc.), seriously impacting the environment (environmental sustainability) for the world population and global economy. Sustainability generally encompasses economic sustainability, environmental sustainability, and social sustainability, and all of these are significantly related to the energy/resource sustainability. This study addresses the sustainability of fuel from the viewpoint of exergy. It is demonstrated that the energy of a fuel is best evaluated by its chemical exergy, and the environmental impact of a fuel can be assessed through the chemical exergy of its emissions (the specific impacts such as toxicity or greenhouse effect are not detailed). Then, the sustainability of fuel can be understood from the viewpoint of exergy through three ways: (a) high chemical exergy of the fuel, (b) high exergy efficiency of the fuel conversion process, and (c) low chemical exergy of the emissions.

One Year of Sustainable Development Research
European Journal of Sustainable Development Research, 2018, 2(1), 01, https://doi.org/10.20897/ejosdr/82777
ABSTRACT: This issue of the European Journal of Sustainable Development Research marks its first anniversary, and demonstrates that the journal has already made a notable impact on the field of sustainable development through having published research on many recent advances. The topics likely to be addressed in the future, and thus covered in the European Journal of Sustainable Development Research, are likely to revolve around the 17 Sustainable Development Goals of the 2030 Agenda for Sustainable Development.

Sustainable Development: A Vital Quest
European Journal of Sustainable Development Research, 2017, 1(1), 2, https://doi.org/10.20897/ejosdr.201702
ABSTRACT: A high-level overview of the discipline of sustainable development is presented, aimed at providing the context and setting for research on and applications of sustainable development, in this lead article to a new journal. The status of sustainable development and its progress are described, as are challenges and needs that may impact its development. Definitions of sustainable development and its interdisciplinary and multidisciplinary dimensions are discussed and contrasted with single-discipline approaches. Examples of interpretations and needs for sustainable development are provided from such fields as energy, resource management, and engineering. Attitudes towards sustainable development are investigated, as is progress. Finally, an illustrative case study is described of a large sustainable development initiative, comprised of several integrated measures and activities.
