New Opportunities for Metals Extraction and Waste Treatment by Electrochemical Processing in Molten Salts - Sadoway, Donald R.
Molten salt electrolysis is a proven technology for the extraction of metals -- all the world's primary aluminum is produced in this manner. The unique properties of molten salts also make them
excellent media in which to treat a variety of forms of waste. Of special note in this regard is
electrolysis in molten oxides, a concept put forward by the author, initially as a "clean technology" for producing primary metal. However, in the context of waste treatment, electrolysis in molten oxides is a process offering the prospect of changing the valence of dissolved heavy metals while making pure oxygen gas as...

The Program on Science, Technology and Environmental Policy: A Research Agenda for the Next Generation of Environmental Regulation - Foster, James Lloyd; Larson, Harold; McCulloch, Lewis
In the view of many industry representatives there already exist technologies with improved
environmental attributes for which it has not been possible to get regulatory approval or even
concerted regulatory review. Is technology now ?getting well ahead? of regulation? Can the
regulatory approval process for new technologies keep up with the opportunities for
innovation? There is a clear need for an objective, credible institutional base for evaluating
technologies that are needed to address contemporary and long-term environmental
problems. The Program in Science Technology and Environmental Policy (PSTEP) being
launched at MIT seeks to be an important part of that institutional base. If the
manufacturer?s claims can be verified,...

Briefing Paper on Industrial Ecology and EPA - Allen, Derry
Industrial Ecology (IE) is a systems approach to efficient resource use and protection of the
environment. Instead of just devising improved methods of waste treatment and disposal, we look for the best
opportunities to reduce waste throughout the total material cycle from virgin materials to finished products to
end of product life. Instead of controlling industrial pollutants from different sources one by one at different
times and with different technologies, we try to look across whole facilities, regions and even whole industries
and make changes wherever in the system it is most effective to do so.
Many thoughtful observers in the research and private and public...
