- Pulping is the process where fibers are separated and treated to produce pulp. The wet pulp is then converted into paper at an integrated pulp and paper mill or is dried and transported from the pulp mill to a paper mill. Different pulping processes are used depending on the fiber material and the desired end product.

Sep 23, 2024 · Pulping is the process of using chemical or mechanical methods, or a combination of both, to dissociate plant fiber raw materials into natural pulp (unbleached pulp) or bleached pulp. The main function of pulping is to provide high-quality pulp for papermaking and other fiber processing industries.
Nov 20, 2023 · With ongoing advancements in pulping technology, pulping methods have evolved beyond purely chemical or mechanical methods. The emergence of biomechanical pulp has revitalized the use of waste crop straw as an essential pulping raw material.
Feb 6, 2023 · The most important mechanical pulping processes are stone groundwood pulping, pressure groundwood pulping, thermomechanical pulping or chemithermomechanical pulping. Wood is ground into pulp during the groundwood pulping process.
