Efforts to Increase Utilization Rate of Recovered Paper
Daio Paper’s utilization rate of recovered paper exceeds industry average as it expanded its usage to include hard-to-recycle recovered paper, which could not have been used in papermaking.

Increasing the Utilization Rate of Recovered Paper in Containerboard Manufacture—Using Hard-To-Recycle Recovered Paper
We use hard-to-recycle recovered paper, which was previously disposed of as waste, as material for containerboard to contribute to a shift to a recycling oriented society. Remodeling our pulping machines (pulper) and improving and reinforcing dust removal equipment (screens) have enabled us to use various types of recovered paper.
Recycling of Old Magazine Paper
We are working to increase the use of old magazine paper in printing and publication paper to increase the use of unused recovered paper.
In conjunction with the launch of the operation of the N10 machine at Mishima Mill, we installed an additional deinked pulp production facility. While pulp recycled from old magazine paper was previously used only in the manufacture of paperboard, with the capacity expansion of deinked pulp production, Daio Paper established a technology to recycle old magazine paper into pulp to use in the manufacture of paper, thereby increasing the total usage amount of recovered paper. As a result, we have expanded the range of recovered paper that can be used to produce paper and improved the utilization rate of recovered paper.
Building that houses paper machine and deinked pulp production facility
By establishing a technology to automatically remove foreign matter such as CDs and DVDs, plastic films, and spine glue, which have posed as a barrier to the use of old magazine paper in papermaking, we expanded the range of the use of recycled magazine paper in papermaking.
