Great potential in Danish Green Biorefinery – from grass to products (2023)
Aarhus University has a unique green biorefinery demonstration platform at AU Viborg, Foulum. Here, The Green Biorefining Technologies Group process and test including agricultural and marine biomasses. The biomass is transformed into products that contribute to a more sustainable and biobased society, such as protein for food, animal feed, biomaterials, bioenergy, and biofertilizers.
In Denmark, there is huge potential for growing more perennial green crops with significant environmental advantages. By increasing our domestic agricultural biomass production and green biorefining capacity, we can begin to rely less heavily on imports like soya.

Grass can be used for more, than you think (2022) (Danish)
In Denmark, we import more than one-million-ton protein per year – mainly soy protein from South America and USA. It’s cost-intensive and not very sustainable. Therefore, there’s a huge potential in the project, GO-GRASS, which Michael Støckler talks about in this video. Cause we can extract protein from grass grown in Denmark for feed to monogastric animals – and then avoid importing protein across the planet. Are you curious to know more about the project, you are welcome to contact Michael Støckler on mcs@foodbiocluster.dk. This video is produced as a part of the GO-GRASS-project (www.go-grass.eu).

GOGRASS: how Danish grass replaces Soy in animal feed (2021)
Soy cultivation and import put enormous pressure on natural areas, biodiversity and our climate. We want to change that! At our CBIO demonstration site we are looking for locally grown and sustainable alternatives for animal feed. We do this in corporation with Food & Bio Cluster Denmark, Velas Rådgivning, Institute for Food Studies & Agro industrial Development - IFAU.

Græs-Prof: A new maceration technique can increase the protein production (2021) (Danish)
In the second year of the Græs-Prof project, the demoplatform at Aarhus University tested a new maceration technique of the grass before it goes into the screw press. The macerated grasses are mixed with green juice from the screw press and the watery slurry is pumped through a Rotacutter and then a Disruptor. This way, the grass material is severe macerated before it goes to the screw press, and it’s easy to feed the screw press without any blocking, which has been a problem with fresh cut grass. Preliminary results have shown that this technique can increase the protein production significant compared to the techniques that previously has been tested at the demo platform.
