Dyed particulate or granular materials from recycled paper and process for making the materials

摘要

In a process for making a particulate or granular material from a reject stream from a coated grade waste paper pulp stock recycling process, fibers for use in making paper are removed, the remaining solid material in the reject stream is dyed and then separated. Water is removed from the reject stream to increase its consistency and form dyed particles or granules. The process and characteristics of particulate and granular material formed by the process are described.
