BTU Develops Biomining Process for Recycling Electronic Waste Using Bacteria and CO2
Researchers at BTU are developing a biomining process to recover metals from electronic waste using microorganisms. This method focuses on extracting valuable metals like copper, gold, and silver from circuit boards with minimal environmental impact. The process is part of the 'BioMinCO2-Convers' project, which includes a demonstration plant in Cottbus, set to begin quasi-continuous operation by early 2027, showcasing the scalability of this biotechnological approach.

BTU researchers are advancing a biomining process for recycling electronic waste, utilizing microorganisms to recover metals such as copper, gold, and silver from circuit boards. This innovative method aims to conserve resources and reduce environmental impact.
The bacteria oxidize iron and sulfur compounds to extract metals, using only small amounts of nutrients and CO as a carbon source. The ongoing development includes a demonstration plant in Cottbus, part of the 'BioMinCO2-Convers' project, set to operate by early 2027. The project involves partnerships with Rhode+Wagner Anlagenbau GmbH and Impala-Süd GmbH to optimize the technology for industrial use.
