Sulfite pulping is a chemical process used to produce wood pulp from lignocellulosic materials, primarily wood. In this method, sulfite chemicals are used to break down the lignin that binds cellulose fibers together, allowing for the separation of these fibers. This process is particularly effective for producing high-quality pulp suitable for making paper and other products. The sulfite pulping process typically involves cooking the wood chips in a solution of sulfite salts and water, often under heat and pressure. The resulting pulp can be bleached to achieve a desired brightness and is valued for its strength and durability. This method is one of several used in the pulp and paper industry.
