Lignins have a long history of use on roads as a method for dust control and surface stabilization. Lignin road products are derived from the lignin that naturally binds cellulose fibers together to give trees and plants firmness. These products are a safe and economical alternative to petroleum and salt-based products that are also sometimes applied to road surfaces.
The original method of applying Lignins to road surfaces for dust control was very simple: dilute raw Lignin solutions were sprayed in light applications onto dirt roads. Over time, road surfaces began to show an improved stabilization, increasing the appeal of using Lignins. Lignin is well suited for a variety of uses such as parking lots, driveways, and road shoulders, where the pavement is too costly and dust conditions become intolerable. Lignosulfonates are used on unpaved roads to reduce environmental concerns from airborne dust particles and to stabilize the road surface.
Lignin Sulfonate does not have any negative impacts on our environment and/or human health. It contains no constituents that are considered hazardous by any Government agency. Further, it’s health rating is 0, which simply means exposure offers little or no risk to either plants or humans. Lignin simply contains no oil based contaminants. Like magnesium chloride, it is soluble in water. Further, lignin is biodegradable.
