   DE moeite waard om te kijken, er is dus zat van dat spul in Europa. www.youtube.com/watch?v=WGG3ndSwUa8

   The complex road to ending the dependence on Chinese rare earths
   
   “America’s dependence on the CCP (Chinese Communist Party) for extraction and processing of these elements,” which Arkansas Sen. Tom Cotton described as “critical to winning the strategic competition against China and protecting our national security.”

   Te veel "BANANA", build absolutely nothing anywhere near anything or anyone en zowiezo teveel regeltjes in Europa, komt niets van, Europa wordt irrelevant.

   Het raffineren van rare earth metals in Europa is vrijwel zeker veel te duur en/of milieutechnisch niet toegestaan.
   
   Lynas verwerkt z'n rare earth materials in Maleisië en ook dat heeft enorm veel problemen opgeleverd.

   Dan moeten we ook niet zeuren als er straks geen metalen beschikbaar zijn voor de EU, we nemen deze metalen wel af maar willen de kinderarbeid, extreme vervuiling niet zien. Hoe schijnheilig is die linkse groene politiek hier wel niet.....

   Europe's Critical Metals Challenge: Dependency & Sustainability
   
   By Strategic Research Institute on Jun 12, 2023 08:00 am
   
   The electrification and digitalization trends sweeping across Europe are driving a growing demand for critical metals in the region's vehicle fleet. However, the current recycling rate of these metals from end-of-life vehicles remains low. Dysprosium, neodymium, manganese, and niobium are highly sought-after metals in the European Union (EU) due to their economic significance, but their supply is limited, making it challenging to scale up raw material production. This increasing dependency on critical metals presents various problems.
   
   The EU heavily relies on imports of these metals since extraction is concentrated in a few countries such as China, South Africa, and Brazil. The lack of availability poses economic and environmental challenges, jeopardizing the transition to electric cars and sustainable technologies. Additionally, the scarcity of these metals raises concerns about future access if existing resources are not effectively utilized. Maria Ljunggren, an Associate Professor in Sustainable Materials Management at Chalmers University of Technology, highlights these pressing issues.
   
   The Critical Raw Materials Act, recently proposed by the European Commission, acknowledges the severity of the situation surrounding critical and strategic raw materials in Europe. The Act emphasizes the importance of enhancing cooperation with reliable external trading partners, improving recycling practices for critical and strategic raw materials, and exploring geological resources within European countries. In Sweden, the state-owned mining company LKAB has reported significant deposits of rare earth metals in Kiruna, which could potentially reduce import dependence in the long run.
   
   Together with the Swiss Federal Laboratories for Materials Science and Technology (EMPA), Ljunggren conducted a survey of metals currently used in Europe's vehicle fleet. This initiative, commissioned by the European Commission's Joint Research Centre (JRC), resulted in the Raw Materials in Vehicles database, providing insights into the presence of metals in new vehicles, vehicles in use, and recycled vehicles over time. The survey, spanning back to 2006, reveals a substantial increase in the proportion of critical metals in vehicles, with rare earth elements showing significant growth.
   
   Neodymium and dysprosium usage in new cars has surged by approximately 400% and 1,700%, respectively, even before the full-scale electrification era. Gold and silver, although not classified as critical metals, have also experienced an 80% increase due to their economic value. The survey aims to provide decision-makers, companies, and organizations with an evidence base for promoting sustainable use of critical metals within the EU. However, the economic challenges associated with recycling these metals, given their low concentrations in each vehicle, remain a significant obstacle.
   
   To achieve greater recycling rates, vehicle design should facilitate metal recovery, and incentives and flexible processes should be implemented to encourage recycling. However, recycling alone may not meet the increasing demand for critical metals in the near future. Therefore, there is a need to explore material substitution and focus on domestic resource extraction to support electrification without hindrance.
