March 13, 1991 ABSTRACT The present invention concerns a process for scrap paper recycling with enzymatic printins ink removal wherein a) a redox potential in the range of 200 to 500 mV is adjusted while metered addition of oxidants and reduc- tives to a solution containing scrap paper takes place simultar.eously, b) a lignine-decomposing reaction is started by adding lignolytical enzymes, c) the reaction is continued in a commercial flotation unit for approxi- mately 10 minutes at 40°C, 0.8 to 2.5 % consistency and a stirring speed of 1,200 to 1,600 rpm, during which period 60 to 80 1 of air/h per 1.5 1 reaction volume is added, and d) the reaction is continued for 60 to 90 minutes during which period the addition and the stir- ring speed are reduced.
