Bleaching is an optional step in the paper manufacturing process that is used to improve the brightness and whiteness of the paper. Bleaching removes residual lignin and other impurities from the fibers, which can cause the paper to turn yellow over time. There are several methods of bleaching used in the paper industry:

The paper industry also generated sludge composed of biomass fly ash and calcareous sludge that is commonly disposed of in landfills. Calcareous sludge can be used in the manufacturing of green geopolymeric mortars for the application in construction. These components are released during the Kraft process of lignin.
