Finding an economically viable utilization of gin waste (cotton gin byproducts) has been topic of research for decades. Over the past few years, developing processes to add-value to gin waste in order to produce marketable products for use as a livestock feed, fuel, erosion control mulches, and/or building materials has been a primary focus of the USDA-ARS gin lab in Lubbock, TX. This paper reports on issues encountered in developing a cotton gin byproduct based hydromulch as well as reports on several erosion studies comparing the cotton-based hydromulch versus conventional hydromulches (wood and paper). Three erosion studies, conducted in 2006, are detailed in the paper. The last study reports on the development of a super hydromulch known as a BioFiber Mat (BFM).
