Innovative solutions in collaboration with Skanska
A key reason for the project’s success was the well-functioning collaboration between Boliden and Skanska, where we jointly developed innovative solutions. These included technical measures such as dredging contaminated sediments and applying a moraine sealing layer to minimize oxygen and water inflow. This ensures that the surrounding environment will not be adversely affected in the future.
A total of nearly 100,000 cubic meters of mining waste was cleaned up and then covered to protect it from both erosion and frost. The project followed a carefully designed remediation plan, incorporating both technical and ecological measures that together can help transform the former mining area into a valuable ecosystem rich in biodiversity.
Continuous monitoring and knowledge development
When the technical remediation at the Rävlidmyr mine was completed, the project entered a new phase focused on creating valuable uses of the terrain. This may include promoting biodiversity that benefits traditional livelihoods such as reindeer herding, which is of great importance to the region.
All of our closed mine sites are continuously monitored through systematic data collection, inspection, and evaluation of environmental impact and stability. This work is carried out in close consultation with relevant stakeholders, with the goal of creating long-term value through our management of closed mines. By actively gathering new knowledge and identifying potential risks, we can continuously improve our remediation efforts. Today, Boliden manages 23 closed mines, from Saxberget in Dalarna to Laisvall in Norrbotten.
