A biorefinery is a facility that converts biomass into energy and other desirable products through refining, i.e. extracting a product from a raw material. This is done to produce new products based on biomass instead of using fossil raw materials. There are many different uses for a biorefinery, including using biomass from forests, food industry residues or agricultural feedstock. Products that can be produced include aviation fuel, chemicals, textiles, but also electricity, heat and fuel.
In the Green Valleys project, the raw material is grass and clover. We want to use the raw material to produce a high-value protein concentrate that can replace imported soy, which is imported from South America and elsewhere and has a major negative impact on the climate.
The background to the project is Denmark’s intensive cereal cultivation, which leads to major nutrient leakage. The aim was to introduce more grass into the crop rotation to bind nutrients in the soil, while perennial plants also increase carbon storage in the soil and reduce the need for artificial fertilisers and pesticides.
