50 Shades of Minerals: Extending & Improving Mineral Resource Lifespans : Opportunities, Challenges, and Future Perspectives

21 May 2025   Conference

The Circular Wallonia Days is a two-day international event taking place on May 21-22, 2025 in Mons, Wallonia (BE). 

As Wallonia takes over the Presidency of the Greater Region* for 2025-2026, it seizes this opportunity to lead discussions on achieving true mineral circularity with all European regions.

A region at the forefront of innovation and spearheading groundbreaking initiatives in mineral circularity, Wallonia offers a unique opportunity for the European mineral industry to engage in collaborative, innovative projects in the circular minerals value chain.

*this includes the Walloon region and the Wallonia-Brussels Federation (Belgium), the former Lorraine region, now Grand-Est (France), the Grand Duchy of Luxembourg and the Länders of Rhineland-Palatinate and Saarland (Germany)

 

KEY TOPICS:

  • Advancing Legislation with Circular Techniques in the Mineral Construction Sector
  • Economic Sustainability of the Circular Materials Model
  • Contribution of Circular Minerals to Sustainable Construction: Inspiration from EU Regions
  • Eco-Design of Circular Materials
  • End-of-Waste and the Right Materials in the Right Place
  • Extending the Lifespan of Construction Materials
  • Resistance to Change in Circular Practices

Additional Highlights:

  • Innovation Talks: Presentation of Walloon and EU Projects in Mineral and Material Circularity for Construction
  • Site Visits: Explore innovative projects in action
  • B2B Sessions: Connect with key stakeholders and partners
