Bleaching of wood pulp is the chemical processing carried out on various types of wood pulp to decrease the color of the pulp, so that it becomes whiter. The main use of wood pulp is to make paper where whiteness (similar to but not exactly the same as "brightness") is an important characteristic. The processes and chemistry described in this article are also applicable to the bleaching of non-wood pulps, such as those made from bamboo or kenaf.

“Worn down by the hoofs of millions of half-wild Texas cattle driven along it to the railheads in Kansas, the trail was a bare, brown, dusty strip hundreds of miles long, lined with the bleaching bones of longhorns and cow ponies. Here and there a broken-down chuck wagon or a small mound marking the grave of some cowhand buried by his partners on the lone prairie gave evidence to the hardships of the journey.”
