Flemish innovation transforms residual streams into microbial protein

In Flanders, ILVO and Bio Base Europe Pilot Plant have taken an important step in scaling up microbial protein production. This technology uses fermentation to produce high-quality proteins from residual streams, such as industrial CO2 or food surpluses. On November 19, new research facilities in Melle and Desteldonk were unveiled, allowing companies and research institutions to conduct tests at both laboratory and pilot scale.

Casein without cows and protein from industrial emissions

One notable project within this infrastructure is the production of microbial casein. This milk protein, suitable for cheese production, is being developed by the Ghent-based scale-up Those Vegan Cowboys without the involvement of animals. At the same time, the steel manufacturer ArcelorMittal is collaborating with UGent to convert CO2 emissions into sustainable ethanol. This ethanol is then fermented into protein, which can serve as an alternative to fishmeal in animal feed.

Residual streams as a resource for food and feed

The new facilities also highlight the potential for utilizing food residual streams. For example, yeast from fruit juice production was processed into protein-rich animal feed, and potato peels were fermented into functional protein powder. Researchers see opportunities for both food applications and the sustainability of animal feed, focusing on poultry and pigs.

Supported by Flanders and Europe, these investments have not only strengthened the Flemish protein strategy but also enhanced the role of microbial protein as a tool in a circular bioeconomy. By scaling up, the sector aims to make this promising protein alternative widely accessible.
