Abstract

Paper industry uses various wet-end chemicals mainly for process control and the production of paper products. Although this industry currently uses various oil-derived chemicals, such as cationic polyacrylamide and poly (aminoamide)-epichlorohydrin, the use of bio-based chemicals derived from lignocelluosic resources has attracted attention since they are renewable and environmentally-friendly. In this review paper, the current status of chemicals used as refining, strength, retention, drainage, formation and sizing additives as well as filler materials in papermaking is discussed. Also, the current application and progress in producing lignocelluloses-derived wet-end chemicals for papermaking is demonstrated. Generally, the main challenge in producing bio-based wet-end chemicals is that naturally occurring lignocelluloses have insufficient properties to be used as wet-end chemicals. Therefore, they should be chemically and/or enzymatically modified so that they could have desired performance.
