AI Insight
Researchers from the Helmholtz Centre for Environmental Research and BOKU University Vienna have developed a hybrid system that combines electrochemical and microbial processes to convert atmospheric CO₂ into itaconic acid, a chemical used in biodegradable plastics production. The process uses yeast paired with electricity to capture carbon dioxide and transform it into this industrially valuable bio-based chemical. The approach could potentially be adapted to produce other valuable chemicals by using different microorganisms.
Why it matters
This technology offers a potential pathway to reduce atmospheric CO₂ while simultaneously producing useful industrial chemicals, addressing both climate change mitigation and sustainable manufacturing. The production of itaconic acid from CO₂ could help replace petroleum-based chemical processes with more environmentally friendly alternatives.
Understand the Science
To limit further climate change, researchers are exploring technologies that can convert atmospheric carbon dioxide (CO₂) into useful products. In collaboration with BOKU University in Vienna (Austria), researchers at the Helmholtz Centre for Environmental Research (UFZ) have demonstrated that electrochemical and microbial processes can be combined to capture CO₂ and produce itaconic acid, a bio-based chemical used in industry. According to the researchers, this new process demonstrates how CO₂ emissions can be converted into sustainable bio-based products, with the potential to produce a wider range of valuable chemicals by using different microorganisms.
