The changes in Chinaʼs Waste Paper procurement policy and the trade friction between the US and China significantly change the amount and quality of used waste paper and affect the procurement of Waste Paper in Japan. In 2018, the Waste Paper procurement situation in Japan is new to memory that the surplus and shortage occurred in a short period due to the influence of external factors.
Furthermore, China has announced that it will target zero solid waste imports at the end of 2020, and it is thought that the import of unsorted Waste Paper will be restricted. In the future, there will be a shortage of high quality Waste Paper and an excess of unsorted waste paper, and the frequency of using low grade waste paper will be increased. For that purpose, it is necessary to strengthen the raw material conditioning equipment to be compatible with low grade Waste Paper. In addition, there is also the possibility that raw material costs can be reduced by using inexpensive low-grade Waste Paper.
In this paper, we will close up on paperboard and introduce the latest Waste Paper processing technology that is effective as a countermeasure along with domestic and overseas achievements for each process.
