A study on recovered secondary fiber for reuse

Cellulose is the main structural elements of paper. However, cellulose from waste paper products can be recover and reuse for papermaking. Moreover, paper manufacturing from recovered cellulose fibers have some differences compare to conventional paper production from pulp. Because cellulose has alreday dry and rewetted in that seconder pulp compared to wood pulp, so the paper strength and physical properties have decreased considerably compared to wood pulp. For improving this situation, it is important to know cellulose properties during recyling. Hence further treatments should be done to improve these quality decreases some level.
