Through the bioeconomic cascade use of the energy crop Silphium perfoliatum, a new regional raw material is produced in addition to biogas: Silphie fibers. Using a biothermal process, OutNature separates the plant fibers of the Silphium and thus obtains high-quality, resource-saving natural fibers that are further processed, in combination with pulp, into Silphie paper. OutNature GmbH was awarded Winner in the German Innovation Awards 2022.
