Circular economy in mines: repurposing of mines

The event will bring together actors working in the field of reuse in mines to share their experiences on different forms of reuse and reuse opportunities in the regions. Through case studies, we will learn about the transformation of mining sites into industrial parks, research and development environments, educational environments, tourism and cultural heritage sites, and underground laboratories for science. We will also have the opportunity to visit Lake Pyhäjärvi Callio, which aims at a comprehensive reuse of the mining environment.
