De Lettinga Award 2022 is uitgereikt aan Dr. Rhiannon Chalmers-Brown voor het COACE project - An innovative system for closing carbon cycles - in de staalindustrie. "A deeper understanding of the bacteria populations and fermentation processes could lead to more efficient bioreactors, and a better carbon capture and utilization", aldus de jury.

Lettinga Award 2022 1


Dit jaar was de prijs bestemd voor 'Innovative technological systems, that include anaerobic processes, for closing cycles', waarop Dr. Rhiannon Chalmers-Brown (Sustainable Environment Research Centre, SERC UK) het COACE project indiende. In dit project wordt gezocht naar een innovatieve manier om koolstof terug te winnen uit gassen uit de staalindustrie mbv anaerobe processen. De prijs is op 22 juni 2022 uitgereikt tijdens de IWA Anaerobic Digestion Conference in Ann Arbor in de VS.

"The COACE process includes a novel extraction system that enables the in-situ extraction of volatile fatty acids (VFAs), whilst recovering and reusing essential nutrients for bacterial growth and maintaining the reactor pH. The project is executed on a pilot scale at the steel industry.

The objective of this project is to investigate the bacterial populations and fermentation metabolisms occurring during the fermentation of blast furnace gas using mixed cultures. Discoveries in this field could lead to significant technological advancement and industrial deployment of fermentation technologies for carbon capture and utilization. A deeper understanding of the mixed cultures present could lead to more efficient bioreactors, able to convert large volumes of gas."
