The green transition requires cooperation and innovation
Business Joensuu and GTK together with companies have formed a cooperation network that develops and offers sustainable solutions for the future needs
of the mining and mineral sector, such as water treatment and recycling, and more efficient utilisation of waste rocks and tailings.
The core of the innovation cluster, Outokumpu Mining Hub, is located in Outokumpu.
Extensive ongoing investment in GTK Mintec’s laboratory facilities, intelligent tailings research, and the digital development environment create a strong foundation for the cluster’s operations.
We are building a globally unique product development and business environment that utilises the special expertise of each cluster operator.

New business opportunities for cluster operators
• Developing international networks
• Strengthening visibility and active marketing cooperation
• Supporting RDI competence
