December 2025: Since April 2023, German and Vietnamese partners have been working together in the CLIENT II project RENO-TITAN to assess titanium ore mining in Vietnam from a radiation protection perspective and to examine options for the safe reuse of the residual sands generated in the process – for example as a substitute for increasingly scarce construction sand. In November 2025, around four months before the project ends, site visits in Vietnam provided an opportunity to discuss the results obtained so far with authorities, industry and research institutions and to plan further steps.
