Additive Manufacturing, AM, is considered to be environmentally friendly when compared to conventional manufacturing processes. Most researchers focus on resource consumption when performing the corresponding Life Cycle Analysis, LCA, of AM. To that end, the sustainability of AM is compared to processes like milling. Nevertheless, factors such as resource use, pollution, and the effects of AM on human health and society should be also taken into account before determining its environmental impact. In addition, in powder-based AM, handling the powder becomes an issue to be addressed, considering both the operator´s health and the subsequent management of the powder used. In view of these requirements, the fundamentals of the different powder-based AM processes were studied and special attention paid to the health risks derived from the high concentrations of certain chemical compounds existing in the typically employed materials. A review of previous work related to the environmental impact of AM is presented, highlighting the gaps found and the areas where deeper research is required. Finally, the implications of the reuse of metallic powder and the procedures to be followed for the disposal of waste are studied.

Climate change has major effects on the planet, and its consequences on today’s society are undeniable. Climate change is the cause of the increased frequency and intensity of extreme weather events including floods. Flood management in Europe has experienced a significant change due to the emergence of the Flood Directive and its implementation in national regulations. The Flood Directive requires the inclusion of the effects of climate change. With multiple factors such as governmental and administrative diversity, and various management tools, each country uses a different methodology. This research conducts a bibliographic review to analyze the methodological approaches applied by four different countries—the United Kingdom, the Netherlands, Germany, and Spain—showing their differences and the causes of such differences and examining the common weaknesses and strengths in the countries’ approach. To this end, it analyzes how to include climate change in the implementation of the Flood Directive in the four countries studied throughout the two cycles. Developing a uniform approach to FD implementation has been hampered by (1) different starting points in the technology of flood prediction, (2) widely varying “traditional” approaches to flood and risk management, and (3) differing levels of the integration of local, regional, and national agencies. Development under the FD has, however, led to increased awareness of the common uncertainty associated with the different current methodologies and the need to deepen the knowledge of climate change as well as the need to develop the technology to reduce said uncertainty.

Ethics is taking a relevant role in this 21st century, in most cases going hand in hand with scientific-technological advances and the social and cultural implications. However, to date, the evidence on which a university in the European Higher Education Area (EHEA) can rely to incorporate the ethical perspective in the educational curriculum successfully is still scarce. To increase the body of knowledge in engineering ethics, this article presents and evaluates the initiative called ’Tecnoetica’ implemented at the University of Deusto, Spain. This initiative proposes to include training in ethical principles, dilemmas, and issues from a holistic and participatory standpoint in which lecturers and students are involved. Because of the initiative, an evaluation rubric is presented as the main contribution from which other centers, universities and/or faculties can benefit.
