BRAIN BioXtractor
Sustainable metal extraction in the circular economy
Precious metals such as gold, silver, platinum or palladium are in greater demand than ever, as they are needed for many high-tech applications. However, ore yields are declining, and ore mining pollutes the environment. The recovery of used precious metals from waste, e.g. from electronic scrap, is therefore becoming increasingly important.
BRAIN AG, a German bioeconomy pioneer, has developed a biological solution for the extraction of valuable metals from secondary raw materials that is not only powerful but also mild and environmentally friendly.
The natural protagonists in this process are microorganisms – identified and optimized by us, they act on the secondary raw materials and extract precious metals with a yield of up to 100% depending on the source material and the type of metal.
BRAIN owns intellectual property rights for the bacteria and processes used and has successfully transferred the technology from laboratory to pilot scale.

The BRAIN BioXtractor:
- is a mobile, fully equipped, self-contained plant on a pilot plant scale;
- contains pioneering technology for bio-based and sustainable metal extraction;
- constitutes a powerful yet safe biological process solution for metal recovery from by-products, waste streams and primary resources;
is suitable for on-site process demonstrations and can be adapted to specific plant requirements.
We’re ready. Are you?
The BRAIN BioXtractor is ready for a test phase at our main site with companies
- who are interested in joint development and marketing;
- who would like to talk to us about licensing the microorganisms involved;
- who want to use the entire technology package at their production sites worldwide.
Are you interested in creating additional value from your resources – e.g. e-scrap, metal-containing filter and shredder dust, ashes, slags, process residues or catalysts – using sustainable technologies? If yes, please contact us!
