Process of treating waste paper by enzymatic de-inking |
| abstract |
The present invention relates to a process for processing waste paper with enzymatic printing ink removal, wherein a) a redox potential in the range from 200 to 500 mV is set while simultaneously adding oxidizing and reducing agents to a solution containing waste paper, b) a lignin-degrading reaction is started by adding lignolytic enzymes and c) the reaction with the addition of 60 to 80 l / h. Air per 1.51 reaction volume, at 40 ° C, 0.8 to 2.5% consistency and a stirrer speed of 1200 to 1600 rpm is continued in a commercial flotation system for about 10 minutes and d) the reaction with reduced supply and reduced stirrer speed 60 continues up to 90 minutes. |
