Technology Turns Contaminated Sediment into Useful Product; Environmental Headache Can Become Valuable Product
Release Date: 03/24/2006
(NEW YORK, NY) The soil we use to landscape our lawns will some day come from contaminated river and harbor sediments, as U.S. EPA Regional Administrator, Alan J. Steinberg demonstrated today in Woodbridge, New Jersey at the first full-scale facility designed to turn this problem into an asset. Joining EPA to tour the facility was U.S. Army Corps of Engineers New York District Engineer Colonel Richard J. Polo, Jr. The technology being showcased uses water under high pressure and biodegradable detergents to strip away contaminants and leave behind soil that can be blended with compost or yard waste to produce high quality top soil. It is patented by BioGenesis Enterprises, Inc. and is being used in the Woodbridge facility to treat more than 4500 cubic yards of contaminated sediment from the lower Passaic River.
The new technology is part of a demonstration program to decontaminate dredged materials from the Port of New York and New Jersey. The program is being funded and implemented by EPA and the New Jersey Department of Transportation (NJDOT). In addition to sediment washing technology, EPA and NJDOT are evaluating a technology that heats the sediment to 2600 degrees Fahrenheit and blends it with cement. This technology, patented by Endesco Clean Harbors, will be used at the International Matex Tank Terminal in Bayonne, New Jersey to treat sediment currently stored in the Valgocen, a large cargo vessel docked on the Raritan River at Bayshore Recycling. Sediment washing and thermal destruction may be among the technologies available for treated dredged sediments from the New York/New Jersey Harbor and large aquatic Superfund sites such as the lower Passaic River, with an ultimate goal of creating a self-sustaining industry that uses treated dredged sediments as building material.
