Cornell engineers bacterium to enhance CO₂ capture and recover metals

A genetically engineered bacterium developed at Cornell University can rapidly break down one of Earth’s most abundant minerals, effectively removing carbon dioxide from the atmosphere while simultaneously recovering critical elements used in electric vehicle batteries. This breakthrough could significantly advance efforts to combat climate change and support the growing demand for sustainable energy solutions.

The urgency of this research stems from the escalating need to address climate change. Carbon dioxide emissions are a major contributor to global warming, and innovative methods to capture and utilize CO₂ are essential. Additionally, the transition to electric vehicles is increasing demand for metals like lithium, cobalt, and nickel, which are essential for battery production. However, traditional mining practices can harm the environment, highlighting the need for more sustainable extraction methods.

The engineered bacterium can process minerals such as olivine, which is rich in magnesium and iron. By breaking down olivine, the bacterium facilitates the capture of CO₂ and releases metals that can be reused in battery production. Early tests indicate that this method could enhance the efficiency of CO₂ capture while also recovering up to 90% of the valuable metals. This dual function positions the research as a potential game-changer in both climate mitigation and resource recovery.

Looking ahead, researchers plan to scale up this technology and conduct field trials to assess its effectiveness in various environments. Success in these endeavors could pave the way for commercial applications, potentially transforming how industries manage carbon emissions and secure critical materials. This innovation not only offers a promising avenue for addressing urgent environmental challenges but also aligns with global efforts to promote greener technologies and sustainable practices.
