Zusammenfassung:	The invention discloses a method that uses esterase obtained by 100 percent deinking and desizing of wasted newspaper controls sticky which mainly aims at producing the low fixed amount newspaper by using the 100 percent deinking and desizing of the wasted newspaper, adopts Optimyze 525 esterase control sticky and produces the newspaper with 45g/mm fixed amount. The invention has the advantages of reducing the dosage of the sticky in the paper pulp, leading the sticky removing rate to be about 20 percent to 40 percent, reinforcing the operating performance of a paper machine, and helping to improve the speed and the output of the paper machine; by adopting deinking and desizing of 100 percent wasted newspaper to make 45g/m lowing amount offset newsprint, the obtained products have good quality, chemical pulp and groundwood pulp which are high in pollution and high consumption are eliminated, the manufactory cost of the pulp material and the processing cost of the water are reduced, and the discharged waste wa
