The Green Biorefining technologies Group work with separating fresh green biomass into a fiber pulp, protein products and a residual liquid known as brown juice., The demonstration platform is a flexible platform that is continuously optimized and innovated – depending on the research- and develop projects it is used for. Here, different plants are tested – like grass, clover, lucerne, after crops, seaweed, and more exotic bio resources like cassava leaves. These plants are processed in the demonstration platform in three levels: the biorefinery, the process hall and the laboratory.
The demonstration platform can process from 3 to 10 ton biomass pr. hour, depending on the biomass. The fresh biomass is put into a maceration process before it is pressed. Different types of maceration and pressing technologies are being tested, compared, and optimized. We are both working with cutting or shredding of the freshly harvested biomass and with mixing the biomass into a liquid process stream and macerated in equipment types fit for pumpable slurries and separated in a two-step dewatering and pressing process. The fiber pulp is assessed according to its protein content – so it can be used for e.g. ruminant feed, biomaterials or bioenergy.
