Lignosulfonate could work as naturally binder as its original form of lignin to bind the cellulose and fiber,so it can be used binding agent in pellets or compressed materials,also could used as dust control agent,which will be much more environment friendly and lower cost compared with Chloride.

How lignosulfonate control the dust

Lignosulfonate binds the road dust surface particle,when evaporate it will become the high-viscosity, naturally sticky material traps dust particles,then after sun heat will make a water resistant durable dust control surface.

Features & Benefits

Environment friendly produce ,non-chemical like chloride.

Reduce dust to PM10 Standards

Can be used on many soil types

Can be used in any places (near water, trees, orchards),will not cause pollution.


Application rates for a topical application are 0.3-0.5 gallons per square yard.


Pre-wet the road before spray the water.

some ways that lignosulfonate can be used as a dust suppressant:

  • Road dust control: It can be applied to unpaved roads, mining sites, construction areas to bind fine particles when they are graded or trafficked. This prevents dust plumes.
  • Stockpile covers: Lignosulfonate sprayed onto coal, ore, soil stockpiles forms a crust that withstands weathering and seals in particles.
  • Ash handling: It controls dust from fly ash and bottom ash during loading, transport or disposal of waste from combustion processes.
  • Agricultural dust: Applied to fields, feedlots and dryyards as a soil binder/stabilizer to minimize airborne particles from tilling, harvesting etc.
  • Landfill dust: Used in daily, intermediate or final cover systems for municipal/construction waste to immobilize exposed waste surfaces.
  • Mining operations: Controls dust from extraction, crushing, conveying material as well as wind erosion of dragline piles and overburden dumps.
  • Synthetic routes: Its polysaccharide structure anchors dust at cement, ceramics, chemical manufacturing sites during material transfers handling.

Key advantages are low usage rates (0.5-3% of dry weight), bonding action even at high temperatures and resilience to weathering with rain. It biodegrades over time with no residue.
