Manufacturing
Newsprint is generally made by a mechanical milling process, without the chemical processes that are often used to remove lignin from the pulp. The lignin causes the paper to rapidly become brittle and yellow when exposed to air and/or sunlight. Traditionally, newsprint was made from fibers extracted from various softwood species of trees (most commonly, spruce, fir, balsam fir or pine). However, an increasing percentage of the world’s newsprint is made with recycled fibers.
