A method for producing antimicrobial paper pulp is provided. The method includes steps of obtaining paper pulp, reducing water content and temperature of the paper pulp, and refining the paper pulp having reduced water content and temperature to improve properties of the paper pulp. The refining may be performed using a refiner with rotating and stationary cutters. The nanocomposite suspension may be added to the refined paper pulp to produce antimicrobial paper pulp. The antimicrobial paper pulp may be drained and pressed to produce paper by applying oil to reduce moisture content of the paper. The paper may be dried without using vapor.
