Abstract
In the past decade, geotextile tubes have emerged as a new technology for dewatering high-water-content dredged sediments from water bodies, by-products, and wastes. These slurry materials are often contaminated and threaten environmental resources if improperly managed. Geotextile tubes present a means to manage these materials in an environmentally responsible and sustainable manner for industrialized and developing countries alike. Keeping sustainability in mind, biodegradable materials and the viability of natural geotextiles for the dewatering and containment system need to be explored. At Syracuse University, the research team has been assessing the viability of using biodegradable geotextiles, natural flocculants, and cellulosic materials for the geotextile tube application. The results, based on both small-scale and large-scale tests, are very promising. This paper provides an overview summary of our studies.
