CEMVITA BIOMINING plans to revolutionize and lower the carbon footprint of the mining industry by application of Industrial Biotech.
Cemvita’s Biomining team works with companies to optimize existing bioprocesses and develop new methods in mineral processing and extractive metallurgy to lower the energy and carbon intensity of the mining industry and enable extraction of the minerals needed for the renewable energy future. Processes that can be enhanced by the latest industrial biotech apply across the entire mining supply chain including mining and mineral pre-processing, in-situ recovery, comminution, leaching, beneficiation and remediation and recycling. We currently have projects in Copper bioleaching and Lithium clay bioextraction.
THE CEMVITA BIOMINING VERTICAL STARTED BECAUSE THE WAY WE MINE FOR THE METALS THAT HUMANS NEED FOR EVERYDAY LIFE, IS TOO ENERGY AND LAND INTENSIVE.
Biotech can change the face of mining the same way it has changed health and food….and we know so much less about microbes that live in rocks and minerals...the field is wide open.

Increasing Metal Removal Capacity during Bioremediation
Microorganisms have been used for the removal of heavy metals from wastes since the early 1990s, however application of biotechnology and synthetic biology now allows us to take things to a whole new level.
For this project, Cemvita Biomining developed an engineered microorganism to facilitate removing heavy metal from acid mine drainage. The engineered species successfully overexpressed metallothioneins (proteins involved with the absorption of heavy metals). As a result, compared to wild type, the engineered cyanobacteria removed Fe, Al, and Ni at much higher rates suggesting the potential of synthetic biology to enhance bioremediation.
As these selected microbes consume CO2 for their growth, this is a significant demonstration of carbon-negative bioremediation. We are currently performing the next phase of this project with the next steps being to determine the heavy metals removal by these engineered microorganisms at pilot scale in the field to assess the long term efficiency of bioremediation.
