焼却処分するしかなかった。[0003] However, polypropylene and the like which are heat-welded by lamination as described above are not easily separated from the base paper in the process of recycling as waste paper.
It cannot be made into a single fiber by the disintegration device. As a result, it was impossible to use it as a raw material for recycled pulp, and it had to be disposed of by incineration.

I couldn't do it even if I wanted to.
