YIPPIE: Yield Preserving Processing to Reduce Emissions

Updated: Jan 29

The pulping industry is facing a new situation, where not only pulp quality but also high yield and emission free processes are demanded. The limited wood based biomass resources need to be utilized in smart ways, and the CO2 emissions in biomass processes reduced whereby retaining carbon in the material. Central tools in this context are to reduce material losses, decrease chemical and water consumption, and improve energy efficiency. This project is focused on ensuring high yield of softwood pulping processes by targeted cleave of bonds and preservation of the typically lost fractions, i.e., pectin, lignin and hemicelluloses.
