UK startup raises €8m of funding to convert CO2 into animal feed

Deep Branch aims to create protein that will replace the use of soy, which has been linked to deforestation

A UK company that turns carbon dioxide into protein to be used for animal feed has raised €8m (£6.8m) in funding as it seeks to displace the use of deforestation-linked soy by farmers.

Carbon and hydrogen are fed to a microorganism in a fermentation process similar to what you would see in a brewery. But rather than alcohol, the output is a high-value protein that can be dried and converted into pellets to feed animals.
