点があった。Particularly in the paper manufacturing industry, the recycling rate of waste paper is increasing. However, it cannot be said that the reuse of waste paper is currently performed on all papers and processed papers. It may be difficult to process some processed papers other than incineration. Conventionally, paperboard impregnated and coated with paraffin has been used, but it has a drawback that it cannot be used as recycled paper.
