At Ressources Mines & Industrie's 2025 Environment, Mining, and Sustainable Development Conference, Maxime Couillard, Vice President of Engineering at ECO2 Magnesia, participated in the "Circular Economy and Restoration of Mining Sites: Valorization of Mine Tailings" roundtable.
This discussion among experts aimed to:
-
Explore how innovation and circular economy principles can transform mine tailings into valuable resources for various industrial sectors (batteries, magnesia, refractories, construction, defense, etc.), from a sustainability perspective.
-
Highlight the main technological, economic, and regulatory challenges that slow down the industrial valorization of mine tailings, while drawing lessons from past experiences.
-
Identify concrete levers for action, whether governmental, industrial, or scientific, as well as market prospects likely to accelerate the integration of mine tailings into supply chains.
This roundtable emphasized the importance of close collaboration among stakeholders to successfully transition toward a more circular and sustainable mining economy.
