Chemical wood pulp, dissolving grades

CPC v2.1 Code: 32111

About chemical wood pulp, dissolving grades

cpc code 32111 covers the production of chemical wood pulp, specifically for dissolving grades. This industry is a crucial component of the broader pulp and paper sector, providing essential raw materials for a wide range of downstream industries, including textiles, pharmaceuticals, and various manufacturing processes. The dissolving wood pulp produced under this code is a highly refined and purified form of cellulose, making it a versatile and valuable input for numerous applications.

Production process

The production of chemical wood pulp, dissolving grades, typically involves a multi-step process. The raw material, which is usually wood chips or other cellulosic feedstock, undergoes a chemical pulping process, often using sulfite or sulfate (kraft) methods, to separate the cellulose fibers from the lignin and other non-cellulosic components. The resulting pulp is then further refined and purified to meet the stringent quality requirements for dissolving grades, which are characterized by their high alpha-cellulose content and low levels of impurities.

Production inputs

The main inputs required for the production of chemical wood pulp, dissolving grades, include wood chips or other cellulosic raw materials, chemicals for the pulping process (such as sulfur compounds or caustic soda), and specialized machinery for pulping, refining, and purification. Additionally, energy sources, water, and skilled labor are essential inputs for this industry.

Production outputs

The primary output of cpc code 32111 is chemical wood pulp, dissolving grades, which is a highly refined and purified form of cellulose. This output is primarily consumed by 13111 Textile fibres and 21001 Pharmaceutical products, as well as other industries that require a high-quality, pure cellulose source for their manufacturing processes.
