The Emerging Technology Program (ETP) supports the development of technologies successfully tested at the bench- and pilot-scale level. The ETP is part of the Superfund Innovative Technology Evaluation (SITE) Program which was established in 1986 under the Superfund Amendments and Reauthorization Act (SARA). The goal of the SITE Program is to promote, accelerate, and make commercially available the development and use of alternative/innovative treatment technologies at hazardous waste sites. Technologies are eligible for the ETP Program when sufficient research data exists validating the technologies' basic concepts. The EPA contributes funds to support developers for one or two years. Developers are responsible for conducting research and providing additional financial support in this cooperative research effort. Technologies are categorized into six areas: thermal, chemical, biological, materials handling, physical, and solidification/stabilization. The technologies' performance, development and data collection are documented and evaluated upon completion of the project. The goal is to accelerate the development of new technologies capable of field demonstration and evaluation. Current information on the ETP program, including a brief introduction and description of the program, is presented in the paper. In addition, summaries of the research on the selected 1991 technologies currently being conducted are provided. (Copyright (c) 1991 Air & Waste Management Association.)
