Wool Blankets for Erosion Control: Research Highlighted in International Publication

Environmental Connection, the magazine of the International Erosion Control Association, published a feature article about Rob Ament’s wool research in its July 2017 issue.  “Bullish for Wool: Using Wool in Erosion Control Blankets Shows Promising Results in Montana Study” summarizes the results of  a WTI project funded by the Montana Department of Transportation (MDT) and the Center for Environmentally Sustainable Transportation in Cold Climates (CESTTiCC). The goal of the field study was to conduct a side-by-side comparison of the performance of wool products with the performance of more commonly used roadside reclamation products (straw/coir ECBs and wood fiber compost). The woolen reclamation products developed for this project demonstrated notable results: all six types of wool erosion control blankets outperformed the control products. Since the project targeted the use of waste wool or other harvested fiber that is substandard or currently unmarketable, the use of this wool for erosion control offers both environmental and economic benefits.  View the article IECA Magazine Bullish On Wool.
