Technical Tasks & Solutions for Improvement of Recycled Pulp Rate

Abstract

The increasing target of domestic wastepaper recycling rate to 60% by the end of 2005 had been achieved 2 years ahead by a result of great effort of various quarters. And today, “increasing the paper recycling rate to 62% by the end of 2010” had been set as a new goal again. About 630,000 t per year wastepaper usage increase is a condition for this new target realization.
Because of the wastepaper recycling rate for board-paper is already more than 90%, increasing of fine wastepaper recycling rate is needed for the 62% target realization. But, the reality is that there is almost no high quality fine wastepaper remain. In addition, in the booming China the low exactly sorted US wastepaper is avoided, the Japanese wastepaper exporting became regular and domestic wastepaper itself is exhausting rapidly.
Innovation and reform in various fields is necessary to achieve recycling rate 62% under such strict situation. In this seminar, I will show the technical tasks and the solutions of efficient use of low quality wastepaper in the stock preparation process that is Aikawa’s field.
