The Department of Energy (DOE) established the Office of Technology Development in 1989 to develop faster and less expensive technical solutions to the Department's widespread environmental problems, primarily the legacy of decades of nuclear weapons production. Without new environmental technologies, DOE contends, some types of contamination may prove impossible to clean up. The Office of Technology Development, which is part of DOE's Environmental Management Program (EM), manages all stages of the development of new environmental restoration and waste management technologies, from basic research and development through final testing, demonstration and evaluation.
