- 1 - A Citizen’s Guide to Innovative Treatment Technologies For Contaminated Soils, Sludges, Sediments, and Debris United States Solid Waste and EPA 542-F-96-001 Environmental Protection Emergency Response April 1996 Agency (5102G) Why Use Innovative Treatment Technologies? • They offer cost-effective, long-term solutions to hazardous waste clean-up problems. • They provide alternatives to land disposal or incineration. • They are often more acceptable to surrounding communities than some established treatment technologies. Technology Innovation Office Technology Fact Sheet Printed on Recycled Paper What are innovative treatment technologies? Treatment technologies are chemical, biological, or physical processes applied to hazardous waste or contami- nated materials to permanently change their condition. This Citizen’s Guide focuses on treatment technologies for soil, sludge, sediment, and debris. Treatment technologies destroy contaminants or change them so that they are no longer hazardous or, at least, are less hazardous. They may reduce the amount of contami- nated material at a site, remove the component of the waste that makes it hazardous, or immobilize the contami- nant within the waste. Innovative treatment technologies are newly invented processes that have been tested and used as treatments for hazardous waste or other contaminated materials, but still lack enough information about their cost and how well they work to predict their performance under a variety of operating conditions. Why use an innovative technology? Treatment of contaminated sludges and soils is a field of technology that has developed and grown since Congress passed the “Superfund” law for contaminated waste site cleanup in 1980. An initial approach to eliminate a hazardous waste from a particular location was to move it somewhere else, or cover it with a cap. These methods use land disposal as the solution to the problem. With an increasing number of cleanups underway, and the passage of amendments to the Superfund law in 1986 that stated a preference for treatment , demand developed for alterna- tives to land disposal that provided more permanent and less costly solutions for dealing with contaminated materials. Development and use of more suitable treat- ment technologies has progressed. As knowledge about the cleanup of contaminated sites increases, new methods for more effective, permanent cleanups will become available. Innovative treatment technologies, which lack a long history of full-scale use, do not have the extensive documentation necessary to make them a standard choice in the engineering/scientific community. However, many innovative technologies have been used successfully at contaminated sites in the United States, Canada, and Europe despite incomplete verifica- tion of their utility. Some of the technologies were developed in response to hazardous waste problems and some have been adapted from other industrial uses. Developing and perfecting treatment technologies is an
