Carbon dioxide (CO2) and carbon monoxide (CO) make up a large proportion of industrial flue gases. Recent research has shown that certain microorganisms are capable of metabolizing these gases into useful by-products, turning the emissions into a useful feedstock, not a waste product.
This article in ScienceDaily discusses new research into a bioelectrosynthetic process in which electroactive bacteria convert CO/CO2 into useful metabolites like acetate and volatile fatty acids. Furthermore this new research may deliver a commercially viable Carbon Capture and Utilisation (CCU) option within 5 years.
