Kraft Lignin (under development)
At our research laboratory, to create new possibilities for the renewable resource “Wood”, we are developing a method for using it as a chemical, focusing on Lignin produced in the pulp manufacturing process.
About Lignin
Lignin, one of the main components of wood, is a phenolic polymer that is responsible for bonding fibers in wood together. Lignin turns brown when exposed to sunlight (ultraviolet rays), so we remove Lignin from wood chips depending on the quality of the paper required. Until now, Lignin extracted in the production process of kraft pulp (hereinafter referred to as "Kraft Lignin") was burned in the paper mill's boiler and used as a heat source. However, going forward, we are advancing research and development with a view to refining Kraft Lignin and effectively utilizing it as a chemical.
Differences from existing Lignin products (Lignin sulfonates)
Kraft Lignin has differences such as being less soluble in water and having a lower molecular weight than the Lignin products (Lignin sulfonates) manufactured by our company.
Expected Applications
Utilizing the reactivity of phenols, applications such as adhesives, resins, activated carbon, wood plastic composites, agricultural mulch films (sheets), and ultraviolet absorbers (sunscreens) are envisaged.
