Waste Paper Recycling

Hard-to-Recycle Recovered Paper Usage

The recyclable fiber uses the difficult stage law of nature waste paper which I was not able to recycle as a waste paper and performs paper and recycling to energy in what only the waste which is not available uses as fuel of the destruction by fire boiler until now.

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.

Utilization of aquatic resources

It is each factory and reuses it about essential aquatic resources in producing paper.The main Mishima Mill is warm by “the Seto Inland Sea climate”, and it is characterized by the one which local, but on the other hand there is relatively little rain, and is poor to aquatic resources which it is easy to spend. I return it to the industrial reservoir and reuse the discharge water to the sea at the time of the shortage of water and usually save water and take measures.
