Beschreibung
Zusammenfassung:	A method for wood pulping including chemically pulping wood chips to a kappa number sufficient to generate a first amount of pulp including a first accepts component and 6 to 50 percent by weight of the first amount of pulp of a first rejects component, separating the first accepts component from the first rejects component, performing a high consistency, substantially mechanical pulping of the first rejects component to generate a second amount of pulp including a second accepts component and a second rejects component, and separating the second accepts component from the second rejects component.
