SUSTAINABLE METAL EXTRACTION
Precious metals such as gold, silver, platinum or palladium are in greater demand than ever because they are required for many high-tech applications. However, the ore yields are falling. In addition, ore mining pollutes the environment. The recovery of installed precious metals from waste, e.g. from electronic scrap, is therefore becoming more important.
Microorganisms help enrich rare earth metals and extract precious metals such as platinum, palladium, silver and gold. Biotechnology thus provides approaches for efficient and environmentally friendly green mining & urban mining. The bioeconomy impressively demonstrates that it is more than the biologization of the chemical or food industry.
The natural protagonists in this process are microorganisms: The identified and optimized microorganisms act on the secondary raw materials and extract precious metals with a yield of up to 100% - depending on the starting material and the type of metal.
