Hazardous waste may be stored, treated and disposed in a variety of ways. Treatment technology exists today for detoxification or destruction of wastes in an environmentally acceptable manner through physical, chemical and biological means. This volume covers several common alternative technologies for treatment of hazardous wastes as well as several emerging alternative technologies that show promise for future application. Thermal destruction of wastes through incineration, reaction with molten glass, etc., is not included as part of this effort. Alternative technologies are taken to be those that provide treatment techniques for waste other than landfilling, landfarming, or lagooning. These alternatives are further subdivided into existing and emerging technologies depending on whether or not they have been proven in full scale tests and adopted for commercial use.
