Paper Title:
Washing Deinking of Mixed Office Wastepaper As a New Resource for Electrical Purposed Paper
  Abstract

In present time, recycled paper from xerographic and laser-printed wastepaper plays an important role as alternatives to paper from virgin pulp because of there good pulp quality and high amount of wastepaper each year. This type of paper is classified as Mixed Office Wastepaper (MOW). The xerographic and laser-printed inks are usually called “toner” that mainly consists of styrene-acrylate copolymer. This work investigated paper recycling by washing deinking processes. Experimental parameters were pulp consistencies, amounts and types of surfactant. The resultant pulp of 1.5%consistency and 0.9 wt% of nonionic surfactant, Triton X-100, is the optimum washing deinking process. The resultant pulps have optical and physical properties closed to non-printed paper. Surfactant concentrations were kept below CMC to provide low ink specks, high brigthness and strength on handsheets. The recycled pulp will be use as a raw material for electrical purpose paper.
