    This scenario explores what could happen if groups of states joined forces with like-minded allies to realize societal goals that can only be attained through an ample supply of raw materials: decarbonization, militarization, digitalization, and securing enough energy to bolster emerging middle classes. By 2030, four alliances emerge. Each one aims to accomplish its own discrete goals, and all are alienated from the others. The EU, which belongs to an alliance of circular economies, asks itself what steps it can take to promote the global stewardship of public goods and civil liberties

    “Nanostandardization” in action: implementing standardization processes in a multidisciplinary nanoparticle-based research and development project

    Nanomaterials have attracted much interest in the medical field and related applications as their distinct properties in the nano-range enable new and improved diagnosis and therapies. Owing to these properties and their potential interactions with the human body and the environment, the impact of nanomaterials on humans and their potential toxicity have been regarded a very significant issue. Consequently, nanomaterials are the subject of a wide range of cutting-edge research efforts in the medical and related fields to thoroughly probe their potential beneficial utilizations and their more negative effects. We posit that the lack of standardization in the field is a serious shortcoming as it has led to the establishment of methods and results that do not ensure sufficient consistency and thus in our view can possibly result in research outputs that are not as robust as they should be. The main aim of this article is to present how NanoDiaRA, a large FP7 European multidisciplinary project that seeks to investigate and develop nanotechnology-based diagnostic systems, has developed and implemented robust, standardized methods to support research practices involving the engineering and manipulation of nanomaterials. First, to contextualize this research, an overview of the measures defined by different regulatory bodies concerning nano-safety is presented. Although these authorities have been very active in the past several years, many questions remain unanswered in our view. Second, a number of national and international projects that attempted to ensure more reliable exchanges of methods and results are discussed. However, the frequent lack of publication of procedures and protocols in research can often be a hindrance for sharing those good practices. Subsequently, the efforts made through NanoDiaRA to introduce standardized methods and techniques to support the development and utilization of nanomaterials are discussed in depth. A series of semi-structured interviews were conducted with the partners of this project, and the interviews were analyzed thematically to highlight the determined efforts of the researchers to standardize their methods. Finally, some recommendations are made towards the setting up of well-defined methods to support the high-quality work of collaborative nanoparticle-based research and development projects and to enhance standardization processes

    Functional materials are crucial to meet today's societal challenges and needs, such as the transition towards low carbon energy production to reduce climate change, renewable energies and green economy, clean mobility and improved communication. In order to fulfill specific functions, many of these materials require a variety of specific metallic elements whose total reserves in primary deposits on the planet are limited in quantity and unevenly distributed, respectively require significant efforts for exploration and investments in their exploitation. Furthermore, the extraction and processing of the corresponding metallic minerals can be sometimes related to a high environmental burden as well as frequently negative social impacts. While in contrast to fossil fuels mineral materials can be principally recycled and hence kept as resources, closing the materials loop especially for many specialty metals today is often hampered by dissipation as well as by physical and economic challenges. These metallic elements are also listed under "critical raw materials" which have been receiving increased attention in scientific and policy-related debates over the last decade and years. In this paper, we introduce the topic of materials criticality for the special issue of Sustainable Materials and Technologies and observe how the criticality of raw materials is perceived and handled within Materials Science. For this, we (i) present examples of critical raw materials in advanced technologies, (ii) summarize some definitions of criticality, (iii) outline the topic of critical raw materials in the Material Scientist community by highlighting relevant outcomes of a survey on critical raw materials for materials scientists, and (iv) conduct a literature research on "Critical Raw Materials" and "Criticality" in search engines commonly used by materials scientists. The results show that material scientists seem frequently not concerned with the criticality of raw materials in their work, and that the relevant terms appear for a broader scientific community mainly in the fields of environmental science, chemistry-related processing and environmental and resource management. The paper presents and discusses these results and suggests to advance the implementation of the concept of materials criticality in materials research and development. (C) 2018 Elsevier B.V.

    The role of industrial actors in the circular economy for critical raw materials: a framework with case studies across a range of industries

    No full text
    In this article, we explore concrete examples of circularity strategies for critical raw materials (CRMs) in commercial settings. We propose a company-level framework for systematically evaluating circularity strategies (e.g., material recycling, product reuse, and product or component lifetime extension) in specific applications of CRMs from the perspectives of specific industrial actors. This framework is applied in qualitative analyses—informed by relevant literature and expert consultation—of five case studies across a range of industries: (1) rhenium in high-pressure turbine components, (2) platinum group metals in industrial catalysts for chemical processing and oil refining, (3) rare earth permanent magnets in computer hard disk drives, (4) various CRMs in consumer electronics, and (5) helium in magnetic resonance imaging (MRI) machines. Drawing from these case studies, three broader observations can be made about company circularity strategies for CRMs. Firstly, there are multiple, partly competing motivations that influence the adoption of circularity strategies, including cost savings, supply security, and external stakeholder pressure. Secondly, business models and value-chain structure play a major role in the implementation of circularity strategies; business-to-business models appear to be more conducive to circularity than business-to-consumer models. Finally, it is important to distinguish between closed-loop circularity, in which material flows are contained within the “focal” actor’s system boundary, and open-loop circularity, in which material flows cross the system boundary, as the latter has limited potential for mitigating material criticality from the perspective of the focal actor.Climate Design and Sustainabilit

    Greater circularity leads to lower criticality, and other links between criticality and the circular economy

    Society requires a stable and secure supply of raw materials. Raw materials supply stability and security are, amongst others, addressed by the concept of raw materials criticality, which focuses on the vulnerability of an economic unit (most commonly a country or region, but also the world, specific sectors, companies or products) to supply restrictions of certain mineral raw materials (cf. Schrijvers et al., 2020). The idea of keeping materials in the economic cycle for longer is specified in the Circular Economy (CE) concept, which encompasses efforts that reduce waste and improve material efficiency (Ellen McArthur Foundation, 2013; European Commission, 2018). So far, CE beyond recycling has not played a prominent role in the criticality debate. At the same time, critical raw materials (CRM) have only been a minor topic in the discussion on CE (recent exceptions include European Commission, 2018, and Gaustad et al., 2018). If properly aligned, criticality assessments might help in defining priority materials for the CE, and circularity strategies could substantially mitigate supply risks. In this paper, we explore the potential benefits, as well as caveats, of adopting a CE approach to CRM, based on our own experiences and our discussions organized by the IRTC (International Round Table on Materials Criticality) project

    The assessment of the criticality of raw materials allows the identification of the likelihood of a supply disruption of a material and the vulnerability of a system (e.g. a national economy, technology, or company) to this disruption. Inconclusive outcomes of various studies suggest that criticality assessments would benefit from the identification of best practices. To prepare the field for such guidance, this paper aims to clarify the mechanisms that affect methodological choices which influence the results of a study. This is achieved via literature review and round table discussions among international experts. The paper demonstrates that criticality studies are divergent in the system under study, the anticipated risk, the purpose of the study, and material selection. These differences in goal and scope naturally result in different choices regarding indicator selection, the required level of aggregation as well as the subsequent choice of aggregation method, and the need for a threshold value. However, this link is often weak, which suggests a lack of understanding of cause-and-effect mechanisms of indicators and outcomes. Data availability is a key factor that limits the evaluation of criticality. Furthermore, data quality, including both data uncertainty and data representativeness, is rarely addressed in the interpretation and communication of results. Clear guidance in the formulation of goals and scopes of criticality studies, the selection of adequate indicators and aggregation methods, and the interpretation of the outcomes, are important initial steps in improving the quality of criticality assessments
