"TUBAF ist ein wichtiger Baustein" – Minister Dulig zur Neuen Sächsischen Rohstoffstrategie

Sachsens Staatsminister für Wirtschaft, Arbeit und Verkehr Martin Dulig war in Freiberg. Hier fand am 11. Januar 2024 die 1. Sächsische Rohstoffkonferenz statt. Diese wurde von der TU Bergakademie Freiberg und Martin Duligs Ministerium gemeinsam ausgerichtet. Auf der Konferenz zog Minister Dulig eine Zwischenbilanz der Neuen Sächsischen Rohstoffstrategie, welche neben den Primär- und Sekundärrohstoffen erstmals auch die nachwachsenden Rohstoffe miteinbezieht. Wir haben Martin Dulig dazu um ein Interview gebeten.  Read more...

International study of lakes: Once oxygen deficient, always oxygen deficient

Anoxia threatens inland waters worldwide. Once it has occurred in a lake, the lack of oxygen even sets in motion a downward spiral that accelerates with increasing global warming. This is indicated by the results of an international study involving researchers of TU Bergakademie Freiberg, which were published in the scientific journal "Global Change Biology". According to the study, lakes that were once affected by a lack of oxygen in deep water are affected again the following year. As a result, the living conditions for fish and invertebrates continue to deteriorate, greenhouse gases are increasingly released and nutrient cycles are intensified.  Read more...

Using clay to combat eternal toxins

PFAS filters available for industrial waste are usually made of activated carbon (PFAS = perfluorinated and polyfluorinated alkyl compounds). As this is comparatively expensive, researchers are looking for alternative filter materials for the so-called "eternal toxins", whose hazardous residues only degrade very slowly in the environment. A team from the TU Bergakademie Freiberg is now proposing a clay made of bentonite modified with organic substances as a possible PFAS filter. The results appear in the current issue of the journal "Chemie Ingenieur Technik".  Read more...

H2 ready? Collaborative project shows use of hydrogen in industrial ovens

Whether for steel and glass production or in many other industrial plants: burners that convert hydrogen into heat instead of natural gas in the future are - alongside electricity from renewable energies - the basis for a successful energy transition in industry. But how can this work when hydrogen has significantly different properties to natural gas? Over the past three years, a research project at TU Bergakademie Freiberg has been investigating solutions for industrial furnaces, industrial heating systems and furnaces. The team from the Chair of Gas and Heating Technology and its partners present the results at the end of the project in Freiberg.  Read more...

Recovering precious metals from electrocatalysts: Scientists develop new process

Hydrogen from electrolysis with renewable energies is considered a key element of the energy transition. By means of catalysts, water is split into its components hydrogen and oxygen. The electrochemical reaction requires precious metals such as platinum, iridium or ruthenium as catalysts. How the recycling of these metals can be improved has been examined for three years by a European research project with the participation of TU Bergakademie Freiberg.  Read more...

Selective extraction – recovery of important industrial metals

Funded by Audi Environmental Foundation, a team of TU Bergakademie Freiberg is researching the recovery of strategically important raw materials. Indium, gallium or tin are not rare, but indispensable for modern technologies, such as semiconductor components or photovoltaic systems. The extraction of these metals is sometimes complex and therefore cost-intensive.  Read more...
