A naturally occurring component of plant life that helps provide strength in plants, lignin is often removed from paper during paper manufacturing to improve the quality and life of the paper.

Its presence in paper may contribute to chemical degradation. Newsprint and various inexpensive or low quality papers that don't have the lignin removed will turn yellow over time. Documents that need a great deal of longevity are printed on archival paper that has had all the lignin removed.
