Abstract
[Object] It is to provide a process of manufacturing recycled paper pulp with high efficiency from newspaper (waste paper) or waste printed paper as a raw material, which is disposed and recovered from homes and offices, through a deinking process using a specific surfactant and electrolyzed water. [Solving Means] A process of obtaining recycled paper pulp from waste printed paper such as waste newspaper as a raw material, including the steps of: cutting waste newspaper or waste printed paper into small pieces; adding alkaline electrolyzed water to the small pieces of waste paper such as waste newspaper, wherein the alkaline electrolyzed water is obtained by electrolysis of water containing a small amount of refined salt; stirring them at a high speed to break down the waste newspaper into fibers; adding the waste newspaper fibers to a stirring vessel; adding an appropriate amount of a liquid surfactant thereto; and then removing ink released to the surface of the solution under gentle stirring, wherein the liquid surfactant is sodium linear alkylbenzene sulfonate.
