PAPER RECYCLING IN JAPAN

The basic treatment processes in recycling recovered paper into recovered pulp are: defibering, dust removal, dispersing, bleaching, deinking, washing and drainage. Because paperboard mills do not have to make pulp white, they usually do not have the ability to conduct the dispersing, bleaching, and deinking processes.
