=== Origin and composition === | |||
Pulping is performed on feedstock with a high fibre content. Before the pulping process, any material that is low in fibrous material should be removed. For example, wood undergoes debarking before the pulping process. Next, the biomass should be [[Sizing|sized]], for example by [[Sizing#Chipping|chipping]].<ref name=":0" /> The most common feedstock for pulping is woody biomass. Examples of non-woody biomass are sisal, rice straw, cotton linen, sugarcane bagasse, pineapple, and straw.<ref name=":1" /> | Pulping is performed on feedstock with a high fibre content.

The resulting product of the pulping process, called pulp, can be further processed into many paper and board products. Depending on the qualities of the pulp, different products are made. Mechanical pulps, which are low quality pulps, are suitable for low-quality paper, such as newspaper, catalogues, paper towels, tissues, and sanitary papers. High quality pulps from chemical pulping are used for printing and writing paper. Finally, the hybrid pulping processes give pulps with stiff fibres and are commonly used in corrugated board, roll cores, and containers.<ref name=":0" /> | The resulting product of the pulping process, called pulp, can be further processed into many paper and board products.
