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.

Usage

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

Recommendations

Pre-wet the road before spray the water.One dirt road dust control study was done by California and focused on eliminating the fine dust that remains suspended in the air and is inhaled.   They discovered that polyvinyl acrylic polymers reduced these fine dust particles by 90%.  Lignosulfonates reduced dust by 20% and calcium chloride 10%.

When it comes down to it, there is no perfect dust control agent for haul roads.  Mine managers have to consider several factors, including soil composition, local environmental regulations, and traffic.
