Abstract

In recent years, the used paper utilization rate has been around 64％, and while the SDGs are being called for, the goal of achieving a used paper utilization rate of 65％ by 2025 has been set. We believe that the use of used paper will continue to increase. However, while the amount of used paper generated is decreasing due to the COVID-19 pandemic and the quality of used paper is also decreasing, the number of sticky foreign substances such as pitches increases and adheres to fabrics, causing poor water extraction, paper break and reduces productivity. Is increasing. At the same time, improvement of product quality is also required, and the situation where difficult problems must be tackled is increasing. In order to improve productivity and quality even under such circumstances, we will introduce measures to remove foreign substances in the papermaking process while using low-grade recycled paper.
