Circular Minerals – Re-Mining or Designing Out Waste

Date: 22.03.2023 - 22.03.2023Location: Hybrid - online or face-to-face Vuorimiehentie 5, Espoo, Finland

Join us to learn how re-mining could help us to acquire the raw materials for the green transition. Can new mines be designed totally waste free? What circular economy opportunities lie in the future mines? Why hasn’t all this been done already? What could the mining industry learn from the forestry industry?

Date: March 22, 2023 at 10.00-16.00

The event consists of two sessions: re-mining and designing out waste. It is organised by Geological Survey of Finland GTK, LUT University, Oulu University and VTT Technical Research Centre of Finland.
