Groningen Seaports
Proteins and platform molecules from CO2

Groningen Seaports is developing an integrated network of new value chains to produce proteins and two platform chemicals from CO2 to demonstrate. With this, they aim to make building blocks for (animal) food and flavour and fragrance ingredients. All this with minimal climate impact.

With the target production volumes, individual technologies, a combination of them, and markets for the products, can be demonstrated and optimised on a near-commercial scale.

Project Groningen Seaports
Purification of CO2
The CO2 is mainly biogenic and collected and purified from waste processes. Production of green hydrogen is via water electrolysis, with renewable electricity. Administration of the gas mix to an innovative fermentation process, yields three products: high-quality acetone, pure and crude ethanol.
Building blocks for vitamins
The high-quality products serve as building blocks for vitamins (for (animal) nutrition) and as solvents for fragrances and flavourings. A second innovative fermentation process converts the lower quality ethanol into microbial protein. This is a valuable and sustainable alternative source of protein in animal feed, replacing fishmeal and soy protein. There are already potential long-term buyers of the products.
