Lignosulfonates are natural polymers derived from the lignin component of wood during the sulfite pulping process. They are water-soluble and have a variety of applications due to their adhesive and dispersing properties. Commonly used in agriculture as soil conditioners and in the production of animal feed, they help improve nutrient absorption. In addition to agricultural uses, lignosulfonates are employed in the construction industry as plasticizers in concrete, enhancing workability and reducing water content. They also find applications in the manufacturing of dyes, inks, and as binders in various industrial processes, showcasing their versatility across multiple sectors.
