Dust is a significant problem for persons who travel on unpaved roadways, various industries and for the nearby environment into which tons of potentially hazardous particulate matter are sent each year. While traditional dust suppressants are widely used, application of such products can pose its own set of potential human and environmental health effects. Dust Stop, a newly developed polysaccaride-based dust suppressant offers the potential to quell transportation and industrial powder related particulate matter in a safer way.
The Polysaccaride Solution
According to Cypher spokesperson Todd Burns, the need for a new type of dust suppressant was obvious from the logistical and environmental problems rife among traditional suppressants. Then, he says, Cypher discovered*polysaccaride derivatives as a tackifier for hydroseeding applications--mixing mulch, seed, fertilizer, and water into a slurry that is sprayed on the ground or used in a dry powder form. "The basic ideas are the same: spraying a substance over the top of a surface and having it stay there for a designated period of time," says Burns. "So we figured if the polysaccaride could bond to the soil surface, it should be able to do so on a road or industrial surface as well."
Burns says Dust Stop can be used on gravel, limestone, dirt, sand, or any other unpaved roadbed or particulate matter application. According to Burns, the liquified*product forms a chemical bond with the particles on the surface of the subject problem, and the larger the particle size, the more efficiently the product will function. "Smaller particles will allow Dust Stop to leach a little farther from the surface," he says, "while material with larger particle sizes will help contain Dust Stop closer to the surface and help it form a thicker layer of binding protection on the top."
Dust Stop promotional materials say the product has been designed for high-, moderate-, and low-temperature applications. Dust Stop is made entirely with natural*polysaccarides that are completely biodegradable. While the exact composition of Dust Stop (as well as its cost information) is proprietary, the company's material safety data sheet identifies it as a "modified polysaccharide". The firm PSC Analytical Services performed the rainbow trout 96-hour pass/fail toxicity test (a test that measures the effect of exposure to a test sample on the survival of young rainbow trout over a 96-hour period) on Dust Stop, and test results showed 0% mortality after 96 hours.
Dust Stop has been tested on unpaved roadways in many countries throughout the world, and is currently being tested on many more from Mongolia to South America. Dust Stop is indeed a viable alternative to traditional dust suppressants and preliminary results suggest that the polysaccaride solution may bring about a healthy resolution to the problem of dusty unpaved roads and industrial projects.
