Resource and energy efficient process technologies

At a time when ore grades decrease and waste streams become increasingly complex, efficient process technologies are key to unlocking the untapped potential of metalliferous primary and secondary resources and provide utilization abilities of tailings materials. With our innovative approaches in mineral processing, metallurgy, recycling, and biotechnology, we extract the maximum value from a given raw material while being more resource and energy efficient, thus contributing to a sustainable circular economy. 

Through national and international collaborations with partners from academia and industry, we facilitate the implementation of our technologies into practise to increase the impact of our research.
