Production as well as fabrication and manufacturing of non-ferrous metals and their alloys are highly resource and energy intensive and connected with high environmental impacts. In the years to come, new major challenges for the non-ferrous metals industry resulting from the transition to a green economy and particularly from the energy turnaround are to be expected in Germany. Against this background, this project aimed at initiating a discussion regarding the role of the non-ferrous metals industry in a green economy, and at identifying scenarios of potential future developments and existing barriers. Besides various stakeholder workshops, the main methodological tool was the Delphi technique. In a Delphi survey with experts from the non-ferrous metals industry, science, consulting and NGOs, probable future innovations among other aspect have been identified. Based on the survey results, potential paths of future development have been developed.
