This review article is motivated by a deceptively simple question: “Can paper products be successfully manufactured with substantially less freshly-obtained cellulosic fibers?” To the extent that this question can be answered in the affirmative, there is potential either to save costs or to decrease future pressure on the world’s forests and other fibrous plants while meeting the requirements of papermakers and their customers.

Such trends will place intense demands upon chemical-based strategies to enhance the bonding within paper and paperboard. Basis weights of various paper-based products can be expected to decrease over the coming decades, and more of the fiber content will be replaced with fillers such as calcium carbonate. In particular, the industry can be expected to view recycling as a central part of its activities. To deal with likely future pressure on forest resources, as well as to hold down costs of materials, publications examined in the preparation of this review suggest that the paper industry will need to implement several concurrent strategies. Paper production requires large amounts of cellulosic fiber, whereas the world’s forested lands and croplands have a finite capacity to supply such resources.
