Documented uses on record

Worldwide, the single largest use of lignosulfonates is as water reducers for concrete. ... Additional large-volume uses of lignosulfonates include animal feed pellet binders, dispersants for gypsum board manufacture, thinners/fluid loss control agents for drilling muds, dispersants/grinding aids for cement manufacture, binders for granulated fertilizers and in dust control applications, particularly road dust abatement, and other specialty dust control applications. /Lignosulfonates/Ligninsulfonic acids are made from native lignin. Two different starting materials are available: (1) lignin made from sulfite pulping and (2) lignin made from alkaline (kraft) pulping of wood. In the first case, the sulfite waste liquor is purified and marketed as a liquid or a solid. Lignin from kraft pulping is first purified and then sulfonated.
