  • The critical raw materials issue between scarcity, supply risk, and unique properties
    Publication . Girtan, Mihaela; Wittenberg, Antje; Grilli, Maria Luisa; De Oliveira, Daniel Pipa Soares; GiosuĂš, Chiara; Ruello, Maria Letizia
    ABSTRACT: This editorial reports on a thorough analysis of the abundance and scarcity distribution of chemical elements and the minerals they form in the Earth, Sun, and Universe in connection with their number of neutrons and binding energy per nucleon. On one hand, understanding the elements’ formation and their specific properties related to their electronic and nucleonic structure may lead to understanding whether future solutions to replace certain elements or materials for specific technical applications are realistic. On the other hand, finding solutions to the critical availability of some of these elements is an urgent need. Even the analysis of the availability of scarce minerals from European Union sources leads to the suggestion that a wide-ranging approach is essential. These two fundamental assumptions represent also the logical approach that led the European Commission to ask for a multi-disciplinary effort from the scientific community to tackle the challenge of Critical Raw Materials. This editorial is also the story of one of the first fulcrum around which a wide network of material scientists gathered thanks to the support of the funding organization for research and innovation networks, COST (European Cooperation in Science and Technology).

    ABSTRACT: GeoERA Minerals projects have produced data aimed at supporting Europe’s minerals sector and to assist the European Commission to realise its goals for raw materials. Data has been compiled on mineral occurrences and mineral provinces across Europe, in particular, areas with potential to host Critical Raw Materials. Anecdotal evidence from the minerals sector provides an indication of the likelihood of exploration leading to mine development. For every 1,000 mineral showings examined, only 100 may receive further exploration work and of those 100, only 10 may warrant more detailed sampling either through trenching, drilling or other means and of those 10 only 1 may proceed to an evaluation through a full feasibility study which itself has only 50% chance of being positive. Following this, any project for which a mine proposal is made must undergo a full evaluation and permitting by authorities including full public consultation. The proposal may or may not pass this scrutiny. In terms of a schedule, the generally accepted minimum time frame from discovery to production is 10 years and usually much more, up to 20 years.
  • Europe’s Raw Materials Supply Chain: Front-End Considerations
    Publication . Wittenberg, Antje; de Oliveira, Daniel Pipa Soares; Bide, Tom; Hollis, Julie; Nirgi, Siim; Ćœibret, Gorazd; Gautneb, HĂ„vard; Sadeghi, Martiya; DomĂ­nguez, Rafael Navarro; Malyuk, Boris
    ABSTRACT: Supply chains are linked for specific purpose and by something. Hence, the respective links of the chain must be hooked in the right place, sufficiently strong, and have to start somewhere. This chapter looks at the raw materials supply chain as the first link in a commodity supply, from the European Union (EU) perspective. Aspects of the raw material potential of critical or strategic mineral resources in Europe, its further exploration, and the concept of modifying factors are considered, and reporting systems of resources and reserves are described, underpinned by examples of mineral potentials in different regions of the EU. Thus, targeted exploration of raw materials, especially within the framework of national geological research, serves to support a sustainable and resilience supply chain. EU projects, such as GeoERA and Geological Service for EU, assist in shaping the tailor-made exploration programs fit for providing mineral data publicly available through EuroGeoSurveys’ European Geological Data Infrastructure. In the future, raw materials may be seen as global public goods required to address many challenges, from the climate crisis to geopolitical instability; therefore, the society could conceptualize them in a new way, from a dominant investment returns-oriented viewpoint to one linked to delivering global objectives.
  • GeoERA raw materials to support Europe’s resilience on raw materials
    Publication . Wittenberg, Antje; De Oliveira, Daniel Pipa Soares; Flindt JĂžrgensen, Lisbeth; GonzĂĄlez, Javier; Heldal, Tom
    Europe’s vision to be a climate neutral economy by 2050 has ushered in the energy transition. Carbon-neutral energy supply is based on raw materials from which energy-critical elements for rechargeable batteries like cobalt, graphite, lithium and rare earth elements can be purified. In addition to direct energy generation, other future-oriented, environmentally friendly key technologies needed for digitisation and mobility can only be engineered by using raw materials (European Commission 2019).
  • GeoERAÂŽs contribution towards resilience in Europe’s raw materials supply chains
    Publication . Wittenberg, Antje; De Oliveira, Daniel Pipa Soares; GonzĂĄlez, Javier; Flindt JĂžrgensen, Lisbeth; Held, Tom
    The well-being of society and the interdependencies of national economies depend heavily on reliably functioning supply chains as the COVID-19 pandemic proved this long-known statement in everyone's daily life. None of the supply chains can do without the mostly mineral raw materials. The United Nations sees raw materials as the key component for achieving all 17 Sustainable Development Goals (SDGs).
  • Critical Raw Material Resource Potentials in Europe
    Publication . Wittenberg, Antje; de Oliveira, Daniel Pipa Soares
    ABSTRACT: The vulnerability of economies and the associated familiar lifestyles have led to numerous policy measures in Europe. The proposed Critical Raw Materials Act (CRMA) sets indicative targets for 2030. A sustainable change in the supply situation requires the targeted exploration of raw materials precisely within the framework of national geological research of suitable detail and in advance of entrepreneurial raw material projects. EU projects like GeoERA assist in shaping the tailor-made exploration programs fit for purpose. GeoERA scientific projects like FRAME and MINDeSEA completed, and updated existing mineral data on CRM are publicly available through EuroGeoSurveys’ European Geological Data Infrastructure (EGDI).
