The Solvay plant in La Rochelle, France, is expanding to meet the growing demand for rare earth metals essential for modern technology. With 70% of rare earth mining and 90% of refining occurring in China, Europe aims to reduce its dependence on Chinese imports. The EU's Critical Raw Materials Act aims to boost local sourcing by 2030. The plant focuses on recycling rare earths and is critical for the European economy, employing over 300 people. The French government supports the facility with tax credits, while the EU seeks to lessen reliance on Chinese exports amidst geopolitical tensions.
