A consortium, including LanzaTech and Danone, led to the discovery of a new route to monoethylene glycol, (MEG), which is a key building block for polyethylene terephthalate, (PET), resin, fibers and bottles. The technology converts carbon emissions from steel mills or gasified waste biomass directly into MEG. The carbon capture technology uses a proprietary engineered bacterium to convert carbon emissions directly into MEG through fermentation, bypassing the need for an ethanol intermediate, and simplifying the MEG supply chain. The direct production of MEG was proven at laboratory scale and the presence of MEG was confirmed by two external laboratories.
“We have made a breakthrough in the production of sustainable PET that has vast potential to reduce the overall environmental impact of the process,” said Dr. Jennifer Holmgren, CEO of LanzaTech. “This is a technological breakthrough which could have significant impact, with applications in multiple sectors, including packaging and textiles!”
