Valmet to Supply BioTrac System for OutNature’s Straw Fiber Pulp Project in Germany

Valmet has been chosen to supply its BioTrac pretreatment and automation system for OutNature’s innovative agro-residue straw fiber pulp project at LEIPA’s paper mill in Schwedt/Oder, Germany. The project aims to diversify raw material sources by converting agricultural residues, specifically straw, into high-quality fiber blends combined with wastepaper. Scheduled for start-up by the end of 2026, the BioTrac system uses continuous steam treatment to efficiently process lignocellulosic materials into fibers suited for papermaking. Straw offers sustainability benefits as it is a by-product of grain farming, requiring no additional land and enabling lower emissions through local sourcing. This initiative supports reducing virgin wood fiber usage while enhancing recycled fiber properties. The delivery includes Valmet’s Pretreatment BioTrac system, DNAe control system, and stock preparation equipment, reinforcing commitments to renewable material circularity and carbon footprint reduction in paper production.
