Abstract
There is disclosed a method for recovering fiber from printed wastepaper by loading the wastepaper and water into a continuous batch fiber recovery apparatus. The wastepaper and water are agitated within the apparatus to form a pulp fiber slurry while introducing a deinking/agglomerating composition at predetermined time intervals to cause the ink particles associated with the printed wastepaper to separate from the paper and agglomerate to form large ink particles. The agglomerated ink particles are then removed from the pulp fiber slurry using separation techniques.
