ABSTRACT:
A method of deinking printed waste paper for recycle which comprises converting a printed waste paper to a fibrous pulp in an aqueous medium to form a fibrous pulp slurry; contacting the slurry with a soybean peroxidase and a peroxide to deink the pulp; separating the deinked pulp from the aqueous medium; and recovering the deinked pulp.
