To increase the profitability of the pulp and paper industry, additional value added products from lignocelluloses are needed, and consistent with this goal, a biorefinery concept based on the sodium carbonate pre-extraction of Trema orientalis prior to pulping was proposed. The solid content in the sodium carbonate pre-extracted liquor was much lower than the hot water pre-extraction, which affected the pre-hydrolysis yield and overall pulp yield positively. The alkaline pre-extraction had a beneficial effect on delignification in the subsequent soda-AQ-pulping. In addition, the alkaline pre-extraction improved the pulp bleachability. The papermaking properties of the alkaline pre-extracted soda-AQ pulp were very close to non-extracted pulp after D0EpD1 bleaching.
