Denmark - Organic protein

Type of grass:

Grassland from nitrate sensitive areas and peatlands


Small-scale biorefinering technology


Organic protein concentrate, renewable energy, nutrients

The demo site in Denmark manages a small green biorefinery for extracting protein from grass. The organic protein concentrate extracted can be fed to pigs and poultry to enrich their diet. Other product streams are a fibrous pulp, that can be used for ruminant feed or biomaterials as well as brown juice that can be used as fertilser.

The facility is working on the optimisation of biorefining processes to provide high yields and high purity of the protein product as well as quality co-products in the form of renewable bioenergy and recycled nutrients. For the validation and documentation of the nutritional value of the products in animal feed, trials will be conducted with local farmers.
