Problem

Denali Materials, located in Anchorage, Alaska, sells virgin asphalt mixes and various polymer-modified grades of asphalt. The area surrounding Denali's facility was victim to the odorous emissions common to the manufacture and transfer of asphalt products, but Denali was determined to suppress odor emissions.

Solution

Denali Materials uses Ecosorb 206A additive during various stages of production and delivery. During a recent visit from an OMI sales engineer, Denali owner Jack Hayden noted two men standing downwind of a tanker truck into which a 40-ton load of polymer-modified asphalt was being transferred. After several minutes, the two men entered the facility and introduced themselves as city health and environmental inspectors, curious to know what was being used to combat the usual odor. The sales engineer was able to describe the science behind the natural Ecosorb solution.

Results

By accounts from both city inspectors, the asphalt odor was eliminated from the airstream within seconds of Ecosorb 206A being added to the transfer. Ecosorb proved to be 100 percent effective at eliminating - not masking - asphalt odor gases at the Denali Materials transfer station.
