Dutch company Aerbio has made strides in the production of animal feed by utilizing CO2 and hydrogen gases at its pilot plant under the project REACT-FIRST. The company's focus on producing a protein called proton for use in feeding salmon and chickens has proven successful, with initial monthly production targets set at 200kg. Aerbio is now progressing towards the development of a Market Launch Facility with significant production capacity and plans for future expansive commercial sites. Aerbio's technology, based on gas conversion through fermentation, not only demonstrates scalability in production but also emphasizes operational flexibility by utilizing industrial CO2 and hydrogen sources without the need for arable land. The company's proton is positioned as a cost-effective alternative to traditional feed ingredients like fishmeal and soy, offering comparable nutritional benefits while being environmentally sustainable. Pete Rowe, the Co-founder and CXO of Aerbio, highlights the promising nutritional profile of proton and its potential to contribute to global food security by offering a reliable protein source. Collaborating with the Sustainable Aquaculture Innovation Centre, Aerbio is nearing the launch of its innovative animal feed products, targeting the poultry and aquaculture sectors for initial trials and market introduction. The article showcases Aerbio's innovative approach to animal feed production, emphasizing sustainability, technological advancement, and the potential for addressing food security challenges. With ongoing trials and ambitious production plans, Aerbio's utilization of CO2 and hydrogen gases presents a positive outlook for the future of animal nutrition.
